kernel: bump 5.4 to 5.4.119
Removed upstreamed: generic/backport-5.4/050-gro-fix-napi_gro_frags-Fast-GRO-breakage-due-to-IP-a.patch bcm63xx/patches-5.4/434-nand-brcmnand-fix-OOB-R-W-with-Hamming-ECC.patch* Removed/code was included upstream and therefore redundant: ramips/patches-5.4/999-fix-pci-init-mt7620.patch All other patches automatically rebased. * update_kernel.sh did not flag this yet it was included in 5.4.119[1], as a result of the rebase, I removed my testing lines since I did not go back to test built or to run test 5.4.119 with the removed patch present. 1. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.4.119&id=e5b3e69eb36ac1178a7a2392616fd29afd288c4e Signed-off-by: John Audia <graysky@archlinux.us>

-Subject: gro: fix napi_gro_frags() Fast GRO breakage due to IP
- alignment check
-
-Commit 7ad18ff6449cbd6beb26b53128ddf56d2685aa93 upstream.
-
-Commit 38ec4944b593 ("gro: ensure frag0 meets IP header alignment")
-did the right thing, but missed the fact that napi_gro_frags() logics
-calls for skb_gro_reset_offset() *before* pulling Ethernet header
-to the skb linear space.
-That said, the introduced check for frag0 address being aligned to 4
-always fails for it as Ethernet header is obviously 14 bytes long,
-and in case with NET_IP_ALIGN its start is not aligned to 4.
-
-Fix this by adding @nhoff argument to skb_gro_reset_offset() which
-tells if an IP header is placed right at the start of frag0 or not.
-This restores Fast GRO for napi_gro_frags() that became very slow
-after the mentioned commit, and preserves the introduced check to
-avoid silent unaligned accesses.
-
-From v1 [0]:
- - inline tiny skb_gro_reset_offset() to let the code be optimized
- more efficively (esp. for the !NET_IP_ALIGN case) (Eric);
- - pull in Reviewed-by from Eric.
