b38758d4d4 kernel: backport fix undefined abort
While building mpi.ko module with stable Linux v4.14.14 an error occured:
>ERROR: "abort" [lib/mpi/mpi.ko] undefined!
In upstream Linux 4.15 this issue is fixed:
Commit 7c2c11b208be ("arch: define weak abort()")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7c2c11b208be09c156573fc0076b7b3646e05219

Commit dc8635b78cd8 ("kernel/exit.c: export abort() to modules")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc8635b78cd8669c37e230058d18c33af7451ab1

So lets add backport patches until these fixes
are not applied in stable version.

02050f7e7d kernel/4.{4, 9}: add manufacturer ID for Winbond NANDs
Some MikroTik devices are using a Winbond NAND flash. Linux treats
it as an unknown NAND before version 4.11:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Unknown NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

Backport a patch from 4.11 to show the manufacturer correctly:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Winbond NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

c13b4ef2c8 kernel: fix compiler warning in mtdsplit_minor.c under 4.4
When mtdsplit_minor.c is compiled under Linux 4.4, the compiler
drops the following warning:

  drivers/mtd/mtdsplit/mtdsplit_minor.c:106:14: note: (near initialization for 'mtdsplit_minor_parser.parse_fn')

The second parameter of the parser function must not have a 'const'
qualifier in 4.4. The 001-mtdsplit_backport.patch removes the qualifier
from other partition parsers. Update it to handle mtdsplit_minor.c as
well.

00a8f349f7 kernel: backport a patch that allows drivers to tweak the TSQ logic
Currently local TCP performance on wifi devices can be limited because
the TSQ (TCP Small Queues) code is tuned for wired ethernet latencies.

With this patch drivers can increase the amount of local buffering to
allow TCP to trigger larger aggregation sizes

This commit is modified from the upstream version to allow #ifdef based
backport feature detection

74f891752b generic: make mtdsplit-tplink.c honor rootfs offset
The splitter ignored the rootfs offset from the header, probably
because until c1e6e61 it was invalid.

This patch fixes the splitter to use the now correct header data.

Regarding target/linux/ar71xx/files/drivers/mtd/tplinkpart.c,
this particular splitter "falls back" to the correct rootfs offset
reading and as such it doesn't need to be updated, although it will
report a kernel partition length that can be larger than the actual
length as it assumes that partition fills the entire segment up to
the rootfs partition.

c08293893a kernel: add support for limiting 4K erase sector support based on flash chip 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.
