OpenWRT changed the default fq_codel sch->limit from 10240 to 1024,
without also adjusting q->flows_cnt. Eric Dumazet explains below that
you must also adjust the buckets (q->flows_cnt) for this not to break.
Eric explains: Limit of 1024 packets and 1024 flows is not wise I think.
(If all buckets are in use, each bucket has a virtual queue of 1 packet,
which is almost the same than having no queue at all)
I suggest to have at least 8 packets per bucket, to let Codel have a
chance to trigger. So you could either reduce number of buckets to 128
(if memory is tight), or increase limit to 8192.
flows_cnt is now set to 1024/8=128

Building for octeon fails with
'arch/mips/vdso/vdso-n32.so.dbg' already contains a '.MIPS.abiflags'
section
if the file already exists from a prior build.
Use the same workaround as the one for vdso.so.dbg committed in
9eb155353a.
Commit 91f205acaf extended the workaround
to cover vdso-o32.so.dbg but missed the vdso-n32.so.dbg which is added
now by this change.

Add a makefile rule to force the rebuild of vdso.so.dbg if genvdso has

This enables misaligned access handling by software in Linux kernel.
With some wireless drivers (ath9k-htc and mt7601u for example) we see
misaligned accesses here and there and to cope with that without
fixing stuff in the drivers we're just gracefully handling it on ARC.

The function memblock_insert_region() is in the section
__init_memblock, also put crashlog_init_memblock there.
This fixes this section mismatch warning:
The function memblock_insert_region.isra.1() references
the function __meminit crashlog_init_memblock().
This is often because memblock_insert_region.isra.1 lacks a __meminit
annotation or the annotation of crashlog_init_memblock is wrong.

The vdso version of this function has some problems with the cache.
Very often it works on dated data which causes problem. We are
currently working on fixing this in upstream Linux kernel.

This reverts commit r48335
The workaround is incomplete and cannot cover all possible cases. The
only real solution to this problem is to disable this feature on
ARM11MPcore entirely.

Given those patches are relevant to any ARC platform and even
ISA version it makes perfect sense for patches to exist
in one place instead of being duplicated for each new ARC-based ASIC.
Note this is a prerequisite for upstreaming of ARC HS38 support in
OpenWRT.
