+Subject: netfilter: conntrack: cache route for forwarded connections
+
+... to avoid per-packet FIB lookup if possible.
+
+The cached dst is re-used provided the input interface
+is the same as that of the previous packet in the same direction.
+
+If not, the cached dst is invalidated.
+
+For ipv6 we also need to store sernum, else dst_check doesn't work,
+pointed out by Eric Dumazet.
+
+This should speed up forwarding when conntrack is already in use
+anyway, especially when using reverse path filtering -- active RPF
+enforces two FIB lookups for each packet.
+
+Before the routing cache removal this didn't matter since RPF was performed
+only when route cache didn't yield a result; but without route cache it
+comes at higher price.
+
+Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
+avoid holding on to dsts of 'frozen' conntracks.

+Subject: [PATCH] bridge: allow setting hash_max + multicast_router if
+ interface is down
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Network managers like netifd (used in OpenWRT for instance) try to
+configure interface options after creation but before setting the
+interface up.
+
+Unfortunately the sysfs / bridge currently only allows to configure the
+hash_max and multicast_router options when the bridge interface is up.
+But since br_multicast_init() doesn't start any timers and only sets
+default values and initializes timers it should be save to reconfigure
+the default values after that, before things actually get active after
+the bridge is set up.

+
+On ARM SoCs with bgmac Ethernet hardware we don't have any normal PHY.

+like in case of MIPS devices.
+We need a fixed PHY to be able to send/receive packets from the switch.

+checksum offload support.
+This significantly improves local TCP tx performance.

+Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
+ to do
+
+Always poll rx and tx during NAPI poll instead of relying on the status
+of the first interrupt. This prevents bgmac_poll from leaving unfinished
+work around until the next IRQ.
+In my tests this makes bridging/routing throughput under heavy load more
+stable and ensures that no new IRQs arrive as long as bgmac_poll uses up
+the entire budget.

+Subject: [PATCH] bgmac: fix DMA rx corruption
+
+The driver needs to inform the hardware about the first invalid (not yet
+filled) rx slot, by writing its DMA descriptor pointer offset to the
+BGMAC_DMA_RX_INDEX register.
+
+This register was set to a value exceeding the rx ring size, effectively
+allowing the hardware constant access to the full ring, regardless of
+which slots are initialized.
+
+To fix this issue, always mark the last filled rx slot as invalid.

+Subject: [PATCH] fib_trie: Fix /proc/net/fib_trie when
+ CONFIG_IP_MULTIPLE_TABLES is not defined
+
+In recent testing I had disabled CONFIG_IP_MULTIPLE_TABLES and as a result
+when I ran "cat /proc/net/fib_trie" the main trie was displayed multiple
+times. I found that the problem line of code was in the function
+fib_trie_seq_next. Specifically the line below caused the indexes to go in
+the opposite direction of our traversal:
+
+ h = tb->tb_id & (FIB_TABLE_HASHSZ - 1);
+
+This issue was that the RT tables are defined such that RT_TABLE_LOCAL is ID
+255, while it is located at TABLE_LOCAL_INDEX of 0, and RT_TABLE_MAIN is 254
+with a TABLE_MAIN_INDEX of 1. This means that the above line will return 1
+for the local table and 0 for main. The result is that fib_trie_seq_next
+will return NULL at the end of the local table, fib_trie_seq_start will
+return the start of the main table, and then fib_trie_seq_next will loop on
+main forever as h will always return 0.
+
+The fix for this is to reverse the ordering of the two tables. It has the
+advantage of making it so that the tables now print in the same order
+regardless of if multiple tables are enabled or not. In order to make the
+definition consistent with the multiple tables case I simply masked the to
+RT_TABLE_XXX values by (FIB_TABLE_HASHSZ - 1). This way the two table
+layouts should always stay consistent.

+Subject: [PATCH] fib_trie: Fix trie balancing issue if new node pushes down
+ existing node
+
+This patch addresses an issue with the level compression of the fib_trie.
+Specifically in the case of adding a new leaf that triggers a new node to
+be added that takes the place of the old node. The result is a trie where
+the 1 child tnode is on one side and one leaf is on the other which gives
+you a very deep trie. Below is the script I used to generate a trie on
+dummy0 with a 10.X.X.X family of addresses.
+
+ ip link add type dummy
+ ipval=184549374
+ bit=2
+ for i in `seq 1 23`
+ do
+ ifconfig dummy0:$bit $ipval/8
+ ipval=`expr $ipval - $bit`
+ bit=`expr $bit \* 2`
+ done
+ cat /proc/net/fib_triestat
+
+Running the script before the patch:
+
+ Local:
+ Aver depth: 10.82
+ Max depth: 23
+ Leaves: 29
+ Prefixes: 30
+ Internal nodes: 27
+ 1: 26 2: 1
+ Pointers: 56
+ Null ptrs: 1
+ Total size: 5 kB
+
+After applying the patch and repeating:
+
+ Local:
+ Aver depth: 4.72
+ Max depth: 9
+ Leaves: 29
+ Prefixes: 30
+ Internal nodes: 12
+ 1: 3 2: 2 3: 7
+ Pointers: 70
+ Null ptrs: 30
+ Total size: 4 kB
+
+What this fix does is start the rebalance at the newly created tnode
+instead of at the parent tnode. This way if there is a gap between the
+parent and the new node it doesn't prevent the new tnode from being
+coalesced with any pre-existing nodes that may have been pushed into one
+of the new nodes child branches.

+Subject: [PATCH] fib_trie: Update usage stats to be percpu instead of
+ global variables
+
+The trie usage stats were currently being shared by all threads that were
+calling fib_table_lookup. As a result when multiple threads were
+performing lookups simultaneously the trie would begin to cache bounce
+between those threads.
+
+In order to prevent this I have updated the usage stats to use a set of
+percpu variables. By doing this we should be able to avoid the cache
+bouncing and still make use of these stats.

+Subject: [PATCH] fib_trie: Make leaf and tnode more uniform
+
+This change makes some fundamental changes to the way leaves and tnodes are
+constructed. The big differences are:
+1. Leaves now populate pos and bits indicating their full key size.
+2. Trie nodes now mask out their lower bits to be consistent with the leaf
+3. Both structures have been reordered so that rt_trie_node now consisists
+ of a much larger region including the pos, bits, and rcu portions of
+ the tnode structure.
+
+On 32b systems this will result in the leaf being 4B larger as the pos and
+bits values were added to a hole created by the key as it was only 4B in
+length.

+Subject: [PATCH] fib_trie: Merge tnode_free and leaf_free into node_free
+
+Both the leaf and the tnode had an rcu_head in them, but they had them in
+slightly different places. Since we now have them in the same spot and
+know that any node with bits == 0 is a leaf and the rest are either vmalloc
+or kmalloc tnodes depending on the value of bits it makes it easy to combine
+the functions and reduce overhead.
+
+In addition I have taken advantage of the rcu_head pointer to go ahead and
+put together a simple linked list instead of using the tnode pointer as
+this way we can merge either type of structure for freeing.

+Subject: [PATCH] fib_trie: Merge leaf into tnode
+
+This change makes it so that leaf and tnode are the same struct. As a
+result there is no need for rt_trie_node anymore since everyting can be
+merged into tnode.
+
+On 32b systems this results in the leaf being 4 bytes larger, however I
+don't know if that is really an issue as this and an eariler patch that
+added bits & pos have increased the size from 20 to 28. If I am not
+mistaken slub/slab allocate on power of 2 sizes so 20 was likely being
+rounded up to 32 anyway.

+Subject: [PATCH] fib_trie: Optimize fib_table_lookup to avoid wasting
+ time on loops/variables
+
+This patch is meant to reduce the complexity of fib_table_lookup by reducing
+the number of variables to the bare minimum while still keeping the same if
+not improved functionality versus the original.
+
+Most of this change was started off by the desire to rid the function of
+chopped_off and current_prefix_length as they actually added very little to
+the function since they only applied when computing the cindex. I was able
+to replace them mostly with just a check for the prefix match. As long as
+the prefix between the key and the node being tested was the same we know
+we can search the tnode fully versus just testing cindex 0.
+
+The second portion of the change ended up being a massive reordering.
+Originally the calls to check_leaf were up near the start of the loop, and
+the backtracing and descending into lower levels of tnodes was later. This
+didn't make much sense as the structure of the tree means the leaves are
+always the last thing to be tested. As such I reordered things so that we
+instead have a loop that will delve into the tree and only exit when we
+have either found a leaf or we have exhausted the tree. The advantage of
+rearranging things like this is that we can fully inline check_leaf since
+there is now only one reference to it in the function.

+Subject: [PATCH] fib_trie: Update meaning of pos to represent unchecked
+ bits
+
+This change moves the pos value to the other side of the "bits" field. By
+doing this it actually simplifies a significant amount of code in the trie.
+
+For example when halving a tree we know that the bit lost exists at
+oldnode->pos, and if we inflate the tree the new bit being add is at
+tn->pos. Previously to find those bits you would have to subtract pos and
+bits from the keylength or start with a value of (1 << 31) and then shift
+that.
+
+There are a number of spots throughout the code that benefit from this. In
+the case of the hot-path searches the main advantage is that we can drop 2
+or more operations from the search path as we no longer need to compute the
+value for the index to be shifted by and can instead just use the raw pos
+value.
+
+In addition the tkey_extract_bits is now defunct and can be replaced by
+get_index since the two operations were doing the same thing, but now
+get_index does it much more quickly as it is only an xor and shift versus a
+pair of shifts and a subtraction.

+Subject: [PATCH] fib_trie: Use unsigned long for anything dealing with a
+ shift by bits
+
+This change makes it so that anything that can be shifted by, or compared
+to a value shifted by bits is updated to be an unsigned long. This is
+mostly a precaution against an insanely huge address space that somehow
+starts coming close to the 2^32 root node size which would require
+something like 1.5 billion addresses.
+
+I chose unsigned long instead of unsigned long long since I do not believe
+it is possible to allocate a 32 bit tnode on a 32 bit system as the memory
+consumed would be 16GB + 28B which exceeds the addressible space for any
+one process.

+Subject: [PATCH] fib_trie: Push rcu_read_lock/unlock to callers
+
+This change is to start cleaning up some of the rcu_read_lock/unlock
+handling. I realized while reviewing the code there are several spots that
+I don't believe are being handled correctly or are masking warnings by
+locally calling rcu_read_lock/unlock instead of calling them at the correct
+level.
+
+A common example is a call to fib_get_table followed by fib_table_lookup.
+The rcu_read_lock/unlock ought to wrap both but there are several spots where
+they were not wrapped.

+Subject: [PATCH] fib_trie: Add functions should_inflate and should_halve
+
+This change pulls the logic for if we should inflate/halve the nodes out
+into separate functions. It also addresses what I believe is a bug where 1
+full node is all that is needed to keep a node from ever being halved.
+
+Simple script to reproduce the issue:
+ modprobe dummy; ifconfig dummy0 up
+ for i in `seq 0 255`; do ifconfig dummy0:$i 10.0.${i}.1/24 up; done
+ ifconfig dummy0:256 10.0.255.33/16 up
+ for i in `seq 0 254`; do ifconfig dummy0:$i down; done

+Subject: [PATCH] fib_trie: Push assignment of child to parent down into
+ inflate/halve
+
+This change makes it so that the assignment of the tnode to the parent is
+handled directly within whatever function is currently handling the node be
+it inflate, halve, or resize. By doing this we can avoid some of the need
+to set NULL pointers in the tree while we are resizing the subnodes.

+Subject: [PATCH] fib_trie: Push tnode flushing down to inflate/halve
+
+This change pushes the tnode freeing down into the inflate and halve
+functions. It makes more sense here as we have a better grasp of what is
+going on and when a given cluster of nodes is ready to be freed.
+
+I believe this may address a bug in the freeing logic as well. For some
+reason if the freelist got to a certain size we would call
+synchronize_rcu(). I'm assuming that what they meant to do is call
+synchronize_rcu() after they had handed off that much memory via
+call_rcu(). As such that is what I have updated the behavior to be.

+Subject: [PATCH] fib_trie: inflate/halve nodes in a more RCU friendly
+ way
+
+This change pulls the node_set_parent functionality out of put_child_reorg
+and instead leaves that to the function to take care of as well. By doing
+this we can fully construct the new cluster of tnodes and all of the
+pointers out of it before we start routing pointers into it.
+
+I am suspecting this will likely fix some concurency issues though I don't
+have a good test to show as such.

+Subject: [PATCH] fib_trie: Remove checks for index >= tnode_child_length
+ from tnode_get_child
+
+For some reason the compiler doesn't seem to understand that when we are in
+a loop that runs from tnode_child_length - 1 to 0 we don't expect the value
+of tn->bits to change. As such every call to tnode_get_child was rerunning
+tnode_chile_length which ended up consuming quite a bit of space in the
+resultant assembly code.
+
+I have gone though and verified that in all cases where tnode_get_child
+is used we are either winding though a fixed loop from tnode_child_length -
+1 to 0, or are in a fastpath case where we are verifying the value by
+either checking for any remaining bits after shifting index by bits and
+testing for leaf, or by using tnode_child_length.

+Subject: [PATCH] fib_trie: Add tracking value for suffix length
+
+This change adds a tracking value for the maximum suffix length of all
+prefixes stored in any given tnode. With this value we can determine if we
+need to backtrace or not based on if the suffix is greater than the pos
+value.
+
+By doing this we can reduce the CPU overhead for lookups in the local table
+as many of the prefixes there are 32b long and have a suffix length of 0
+meaning we can immediately backtrace to the root node without needing to
+test any of the nodes between it and where we ended up.

+Subject: [PATCH] fib_trie: Fix RCU bug and merge similar bits of inflate/halve
+
+This patch addresses two issues.
+
+The first issue is the fact that I believe I had the RCU freeing sequence
+slightly out of order. As a result we could get into an issue if a caller
+went into a child of a child of the new node, then backtraced into the to be
+freed parent, and then attempted to access a child of a child that may have
+been consumed in a resize of one of the new nodes children. To resolve this I
+have moved the resize after we have freed the oldtnode. The only side effect
+of this is that we will now be calling resize on more nodes in the case of
+inflate due to the fact that we don't have a good way to test to see if a
+full_tnode on the new node was there before or after the allocation. This
+should have minimal impact however since the node should already be
+correctly size so it is just the cost of calling should_inflate that we
+will be taking on the node which is only a couple of cycles.
+
+The second issue is the fact that inflate and halve were essentially doing
+the same thing after the new node was added to the trie replacing the old
+one. As such it wasn't really necessary to keep the code in both functions
+so I have split it out into two other functions, called replace and
+update_children.

+Subject: [PATCH] fib_trie: Fall back to slen update on inflate/halve failure
+
+This change corrects an issue where if inflate or halve fails we were
+exiting the resize function without at least updating the slen for the
+node. To correct this I have moved the update of max_size into the while
+loop so that it is only decremented on a successful call to either inflate
+or halve.

+Subject: [PATCH] fib_trie: Add collapse() and should_collapse() to resize
+
+This patch really does two things.
+
+First it pulls the logic for determining if we should collapse one node out
+of the tree and the actual code doing the collapse into a separate pair of
+functions. This helps to make the changes to these areas more readable.
+
+Second it encodes the upper 32b of the empty_children value onto the
+full_children value in the case of bits == KEYLENGTH. By doing this we are
+able to handle the case of a 32b node where empty_children would appear to
+be 0 when it was actually 1ul << 32.

+Subject: [PATCH] fib_trie: Various clean-ups for handling slen
+
+While doing further work on the fib_trie I noted a few items.
+
+First I was using calls that were far more complicated than they needed to
+be for determining when to push/pull the suffix length. I have updated the
+code to reflect the simplier logic.
+
+The second issue is that I realised we weren't necessarily handling the
+case of a leaf_info struct surviving a flush. I have updated the logic so
+that now we will call pull_suffix in the event of having a leaf info value
+left in the leaf after flushing it.

+Subject: [PATCH] pppoe: Use workqueue to die properly when a PADT is received
+
+When a PADT frame is received, the socket may not be in a good state to
+close down the PPP interface. The current implementation handles this by
+simply blocking all further PPP traffic, and hoping that the lack of traffic
+will trigger the user to investigate.
+
+Use schedule_work to get to a process context from which we clear down the
+PPP interface, in a fashion analogous to hangup on a TTY-based PPP
+interface. This causes pppd to disconnect immediately, and allows tools to
+take immediate corrective action.
+
+Note that pppd's rp_pppoe.so plugin has code in it to disable the session
+when it disconnects; however, as a consequence of this patch, the session is
+already disabled before rp_pppoe.so is asked to disable the session. The
+result is a harmless error message:
+
+Failed to disconnect PPPoE socket: 114 Operation already in progress
+
+This message is safe to ignore, as long as the error is 114 Operation
+already in progress; in that specific case, it means that the PPPoE session
+has already been disabled before pppd tried to disable it.

+Subject: [PATCH] ipv6: ip6_fragment: fix headroom tests and skb leak
+
+David Woodhouse reports skb_under_panic when we try to push ethernet
+header to fragmented ipv6 skbs:
+
+ skbuff: skb_under_panic: text:c1277f1e len:1294 put:14 head:dec98000
+ data:dec97ffc tail:0xdec9850a end:0xdec98f40 dev:br-lan
+[..]
+ip6_finish_output2+0x196/0x4da
+
+David further debugged this:
+ [..] offending fragments were arriving here with skb_headroom(skb)==10.
+ Which is reasonable, being the Solos ADSL card's header of 8 bytes
+ followed by 2 bytes of PPP frame type.
+
+The problem is that if netfilter ipv6 defragmentation is used, skb_cow()
+in ip6_forward will only see reassembled skb.
+
+Therefore, headroom is overestimated by 8 bytes (we pulled fragment
+header) and we don't check the skbs in the frag_list either.
+
+We can't do these checks in netfilter defrag since outdev isn't known yet.
+
+Furthermore, existing tests in ip6_fragment did not consider the fragment
+or ipv6 header size when checking headroom of the fraglist skbs.
+
+While at it, also fix a skb leak on memory allocation -- ip6_fragment
+must consume the skb.
+
+I tested this e1000 driver hacked to not allocate additional headroom
+(we end up in slowpath, since LL_RESERVED_SPACE is 16).
+
+If 2 bytes of headroom are allocated, fastpath is taken (14 byte
+ethernet header was pulled, so 16 byte headroom available in all
+fragments).

+Subject: [PATCH] solos-pci: Increase headroom on received packets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+A comment in include/linux/skbuff.h says that:
+
+ * Various parts of the networking layer expect at least 32 bytes of
+ * headroom, you should not reduce this.
+
+This was demonstrated by a panic when handling fragmented IPv6 packets:
+http://marc.info/?l=linux-netdev&m=144236093519172&w=2
+
+It's not entirely clear if that comment is still valid — and if it is,
+perhaps netif_rx() ought to be enforcing it with a warning.
+
+But either way, it is rather stupid from a performance point of view
+for us to be receiving packets into a buffer which doesn't have enough
+room to prepend an Ethernet header — it means that *every* incoming
+packet is going to be need to be reallocated. So let's fix that.

+Subject: [PATCH] regmap: make LZO cache optional
+
+Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
+for LZO compression in regcache, but there were never any users added
+afterwards. Since LZO support itself has its own size, it currently is
+rather a deoptimization.
+
+So make it optional by introducing a symbol that can be selected by
+drivers wanting to make use of it.
+
+Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).

+I tried using google to find any users (even out-of-tree ones), but at
+best I found a single driver submission that was switched to RBTREE in
+subsequent resubmissions (MFD_SMSC).
+
+One could maybe also just drop the code because of no users for 5 years,
+but that would be up to the maintainer(s) to decide.

+
+The work directory is needed for atomic copy-up and similar. It is not actually
+necessary to mount a read-only overlay. Post 4.0 it is possible to mount the
+overlay without workdir (but even then it won't happen automatically in case the
+upper fs is full, so this should be fixed in the latest kernel too).
+
+Could you please try the following patch? If the workdir can't be created it
+will fall back to mounting the overlay read-only.
+
+Thanks,
+Miklos

+Subject: [PATCH] spi: Pump transfers inside calling context for spi_sync()
+
+If we are using the standard SPI message pump (which all drivers should be
+transitioning over to) then special case the message enqueue and instead of
+starting the worker thread to push messages to the hardware do so in the
+context of the caller if the controller is idle. This avoids a context
+switch in the common case where the controller has a single user in a
+single thread, for short PIO transfers there may be no need to context
+switch away from the calling context to complete the transfer.
+
+The code is a bit more complex than is desirable in part due to the need
+to handle drivers not using the standard queue and in part due to handling
+the various combinations of bus locking and asynchronous submission in
+interrupt context.
+
+It is still suboptimal since it will still wake the message pump for each
+transfer in order to schedule idling of the hardware and if multiple
+contexts are using the controller simultaneously a caller may end up
+pumping a message for some random other thread rather than for itself,
+and if the thread ends up deferring due to another context idling the

+Subject: [PATCH] spi: Only idle the message pump in the worker kthread
+
+In order to avoid the situation where the kthread is waiting for another
+context to make the hardware idle let the message pump know if it's being
+called from the worker thread context and if it isn't then defer to the
+worker thread instead of idling the hardware immediately. This will ensure
+that if this situation happens we block rather than busy waiting.

+
+u
+This fixes breakage to iproute2 build with recent kernel headers
+caused by:
+ commit a263653ed798216c0069922d7b5237ca49436007
+ Author: Pablo Neira Ayuso <pablo@netfilter.org>
+ Date: Wed Jun 17 10:28:27 2015 -0500
+
+ netfilter: don't pull include/linux/netfilter.h from netns headers
+
+The issue is that definitions in linux/in.h overlap with those
+in netinet/in.h. This patch solves this by introducing the same
+mechanism as was used to solve the same problem with linux/in6.h

+Subject: [PATCH] mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
+
+[ Upstream commit 19be0eaffa3ac7d8eb6784ad9bdbc7d67ed8e619 ]
+
+This is an ancient bug that was actually attempted to be fixed once
+(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
+get_user_pages() race for write access") but that was then undone due to
+problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").
+
+In the meantime, the s390 situation has long been fixed, and we can now
+fix it by checking the pte_dirty() bit properly (and do it better). The
+s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
+software dirty bits") which made it into v3.9. Earlier kernels will
+have to look at the page state itself.
+
+Also, the VM has become more scalable, and what used a purely
+theoretical race back then has become easier to trigger.
+
+To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
+we already did a COW" rather than play racy games with FOLL_WRITE that
+is very fundamental, and then use the pte dirty flag to validate that
+the FOLL_COW flag is still valid.

+Subject: [PATCH] module_arch_freeing_init(): new hook for archs before module->module_init freed.
+
+Archs have been abusing module_free() to clean up their arch-specific
+allocations. Since module_free() is also (ab)used by BPF and trace code,
+let's keep it to simple allocations, and provide a hook called before
+that.
+
+This means that avr32, ia64, parisc and s390 no longer need to implement
+their own module_free() at all. avr32 doesn't need module_finalize()
+either.

+Subject: [PATCH 11/12] USB: EHCI: add ignore_oc flag to disable overcurrent
+ checking
+
+This patch adds an ignore_oc flag which can be set by EHCI controller
+not supporting or wanting to disable overcurrent checking. The EHCI
+platform data in include/linux/usb/ehci_pdriver.h is also augmented to
+take advantage of this new flag.

+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+Subject: [PATCH] MIPS: partially inline dma ops
+
+Several DMA ops are no-op on many platforms, and the indirection through
+the mips_dma_map_ops function table is causing the compiler to emit
+unnecessary code.
+
+Inlining visibly improves network performance in my tests (on a 24Kc
+based system), and also slightly reduces code size of a few drivers.

+Subject: [PATCH] MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16
+
+Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with
+MIPS32 instructions into another function with MIPS16 code [1], causing
+the assembler to genereate incorrect binary code or fail right away
+complaining about unrecognized opcode.
+
+In the case of __arch_swab{16,32}, when inlined by the compiler with
+flags `-mips32r2 -mips16 -Os', the assembler can fail with the following
+error.
+
+ {standard input}:79: Error: unrecognized opcode `wsbh $2,$2'
+
+For performance concerns and to workaround the issue already existing in
+older compilers, just ignore these 2 functions when compiling with
+mips16 enabled.
+
+ [1] Inlining nomips16 function into mips16 function can result in
+ undefined builtins, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55777

+Subject: [PATCH 4/8] mtd: part: add generic parsing of linux,part-probe
+
+This moves the linux,part-probe device tree parsing code from
+physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
+providing a reference to their device tree node in struct
+mtd_part_parser_data.

+
+BCM5301X devices may contain some partitions in higher memory, e.g.
+Netgear R8000 has board_data at 0x2600000. To detect them we should
+use size limit on MIPS only.

+Subject: [PATCH] cdc_ncm: Add support for moving NDP to end of NCM frame
+
+NCM specs are not actually mandating a specific position in the frame for
+the NDP (Network Datagram Pointer). However, some Huawei devices will
+ignore our aggregates if it is not placed after the datagrams it points
+to. Add support for doing just this, in a per-device configurable way.
+While at it, update NCM subdrivers, disabling this functionality in all of
+them, except in huawei_cdc_ncm where it is enabled instead.
+We aren't making any distinction between different Huawei NCM devices,
+based on what the vendor driver does. Standard NCM devices are left
+unaffected: if they are compliant, they should be always usable, still
+stay on the safe side.
+
+This change has been tested and working with a Huawei E3131 device (which
+works regardless of NDP position), a Huawei E3531 (also working both
+ways) and an E3372 (which mandates NDP to be after indexed datagrams).
+
+V1->V2:
+- corrected wrong NDP acronym definition
+- fixed possible NULL pointer dereference
+- patch cleanup
+V2->V3:
+- Properly account for the NDP size when writing new packets to SKB

+Subject: [PATCH] usb: ehci-orion: fix probe for !GENERIC_PHY
+
+Commit d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
+added support for optional phys, but devm_phy_optional_get returns
+-ENOSYS if GENERIC_PHY is not enabled.
+
+This causes probe failures, even when there are no phys specified:
+
+[ 1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38
+[ 1.449403] orion-ehci: probe of f1058000.usb failed with error -38
+
+Similar to dwc3, treat -ENOSYS as no phy.
+
+Fixes: d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")

+Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo from sys/sysinfo.h.
+so for now, only include it on glibc or when including from kernel
+in order not to break their headers.

+Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
+
+Musl provides the same structs as glibc, but does not provide a define to
+allow its detection. Since the absence of __GLIBC__ also can mean that it
+is included from the kernel, change the __GLIBC__ detection to
+!__KERNEL__, which should always be true when included from userspace.

+
+Musl provides its own ethhdr struct definition. Add a guard to prevent
+its definition of the appropriate musl header has already been included.

+Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional
+Date: Mon, 7 Apr 2014 12:57:04 +0200
+Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>
+
+This small patch makes the MIPS FPU emulator optional. The kernel
+kills float-users on systems without a hardware FPU by sending a SIGILL.
+
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
+optimizing for size).
+
+Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>
+---
+v4: rediffed because of patch 1/2, should now work with micromips as well
+v3: updated patch description with size savings.
+v2: incorporated changes suggested by Jonas Gorski
+ force the fpu emulator on for micromips: relocating the parts
+ of the mmips code in the emulator to other areas would be a
+ much larger change; I went the cheap route instead with this.

++
++ If you need code which can detect and parse these tables, and

++
++ You will still need the parsing functions to be called by the driver

+Subject: [PATCH 3/7] skb_reduce_truesize: helper function for shrinking skbs
+ whenever needed
+
+On embedded devices in particular, large queues of small packets from the rx
+path with a large truesize can exist. Reducing their size can reduce
+memory pressure. skb_reduce_truesize is a helper function for doing this,
+when needed.

+From 775d6fe74d1eaec2ba387535b068dde2dc89de9e Mon Sep 17 00:00:00 2001

+Date: Thu, 22 May 2014 09:49:05 +0200
+Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: [PATCH] ipv6: Fixed source specific default route handling.
+
+If there are only IPv6 source specific default routes present, the
+host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
+calls ip6_route_output first, and given source address any, it fails,
+and ip6_route_get_saddr is never called.
+
+The change is to use the ip6_route_get_saddr, even if the initial
+ip6_route_output fails, and then doing ip6_route_output _again_ after
+we have appropriate source address available.
+
+Note that this is '99% fix' to the problem; a correct fix would be to
+do route lookups only within addrconf.c when picking a source address,
+and never call ip6_route_output before source address has been
+populated.

+Subject: NET: skip GRO for foreign MAC addresses
+
+For network drivers using napi_gro_receive, packets are run through GRO,
+even when the destination MAC address does not match, and they're supposed
+to be delivered to another host behind a different bridge port.
+
+This can be very expensive, because for drivers without TSO or scatter-
+gather, this can only be undone by copying the skb and checksumming it
+again.
+
+To be able to track foreign MAC addresses in an inexpensive way, create
+a mask of changed bits in MAC addresses of upper devices. This allows
+handling VLANs and bridge devices with different addresses (as long as
+they are not too different).

+Subject: NET: add of_get_mac_address_mtd()
+
+Many embedded devices have information such as mac addresses stored inside mtd
+devices. This patch allows us to add a property inside a node describing a
+network interface. The new property points at a mtd partition with an offset
+where the mac address can be found.

+ 8139cp: Fix DMA unmapping of transmitted buffers
+
+ The low 16 bits of the 'opts1' field in the TX descriptor are supposed
+ to still contain the buffer length when the descriptor is handed back to
+ us. In practice, at least on my hardware, they don't. So stash the
+ original value of the opts1 field and get the length to unmap from
+ there.
+
+ There are other ways we could have worked out the length, but I actually
+ want a stash of the opts1 field anyway so that I can dump it alongside
+ the contents of the descriptor ring when we suffer a TX timeout.

+ 8139cp: Do not re-enable RX interrupts in cp_tx_timeout()
+
+ If an RX interrupt was already received but NAPI has not yet run when
+ the RX timeout happens, we end up in cp_tx_timeout() with RX interrupts
+ already disabled. Blindly re-enabling them will cause an IRQ storm.
+
+ (This is made particularly horrid by the fact that cp_interrupt() always
+ returns that it's handled the interrupt, even when it hasn't actually
+ done anything. If it didn't do that, the core IRQ code would have
+ detected the storm and handled it, I'd have had a clear smoking gun
+ backtrace instead of just a spontaneously resetting router, and I'd have
+ at *least* two days of my life back. Changing the return value of
+ cp_interrupt() will be argued about under separate cover.)
+
+ Unconditionally leave RX interrupts disabled after the reset, and
+ schedule NAPI to check the receive ring and re-enable them.

+Subject: [PATCH] libata: add ledtrig support
+To: linux-ide@vger.kernel.org,
+ Tejun Heo <tj@kernel.org>
+
+This adds a LED trigger for each ATA port indicating disk activity.
+
+As this is needed only on specific platforms (NAS SoCs and such),
+these platforms should define ARCH_WANTS_LIBATA_LEDS if there
+are boards with LED(s) intended to indicate ATA disk activity and
+need the OS to take care of that.
+In that way, if not selected, LED trigger support not will be
+included in libata-core and both, codepaths and structures remain
+untouched.
