Some targets deactivated CONFIG_SYN_COOKIES, for unknown reasons, use
the default setting from the generic configuration which activates
CONFIG_SYN_COOKIES.
This should prevent SYN flooding.

CONFIG_COMPAT_BRK disables the heap randomization which is only needed
for very old and ancient user space applications, I am not aware that we
run any of these, just deactivate this option for these targets to allow
heap randomization.

This patch is to upgrade kernel to 4.14 for layerscape.
patches-4.14 for layerscape included two categories.
- NXP Layerscape SDK kernel-4.14 patches
All patches on tag LSDK-18.09-V4.14 were ported to OpenWrt
kernel. Since there were hundreds patches, we had to make
an all-in-one patch for each IP/feature.
See below links for LSDK kernel.
https://lsdk.github.io/components.html
https://source.codeaurora.org/external/qoriq/qoriq-components/linux
- Non-LSDK kernel patches
Other patches which were not in LSDK were just put in patches-4.14.
Kept below patches from patches-4.9.
303-dts-layerscape-add-traverse-ls1043.patch
821-add-esdhc-vsel-to-ls1043.patch
822-rgmii-fixed-link.patch
Renamed and rebase them as below in patches-4.14,
303-add-DTS-for-Traverse-LS1043-Boards.patch
712-sdk-dpaa-rgmii-fixed-link.patch
824-mmc-sdhci-of-esdhc-add-voltage-switch-support-for-ls.patch

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash

Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
for virtual targets such as malta or potent ones like x86.
This saves up to 4KB of uncompressed kernel size and significantly
decreases CPU load under certain workloads.

Default profile had to enable many packages for all devices
support. This made these packages still enabled when built
for single device. This patch is to remove default profile.
For multiple devices build, it's proper to build with multiple
devices profile.

size
Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.
Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.
