This patch was introduced in commit r16412 for the brcm47xx target only
and then moved to generic in commit r32395. It was initially added
because of ticket #5186 and should fix some problems with fuse file
systems and MIPS caches. The commit comment in r32395 says that this a
generic problem in MIPS CPUs, but does not name any specifics about
that. There was a fix added to kernel 2.6.21 in commit commit
7575a49f20 "[MIPS] Implement flush_anon_page()." that should fix this
problem, but that was already available before both commits were done
to OpenWrt.
I just tested fuse with ntfs.3g without this patch on a BCM4704
(BMIPS3300 V0.6) SoC and haven't seen any problems. Someone reported
that removing this patch improves some fuse operations by 5 times on
some modern MIPS cores.
My test was only a simple "dd if=/dev/zero of=/mnt/zero bs=5000" to an
USB stick.
This patch removes the patch to OpenWrt, because I assume that it is
not needed any more and Felix, the orginal author, also thinks so.

In the upstream kernel and the upstream squashfs4 tools the xz
compression header looks the following:
struct disk_comp_opts {
__le32 dictionary_size;
__le32 flags;
};
We added some other members and also moved some existing members. Place
the members which are already in upstream header at the same position
as in that kernel and add our own at the end. The kernel should not
have a problem when there are some additional members and just ignore
them.

In kernel 4.7 there is upstreamed b53 driver using (mostly?) the same
symbols as our b53 does. Change our symbols so both drivers can coexist
in kernel tree.

So far "kernel" partition didn't contain just a kernel. It also included
Seama header and meta data. This was making kernel update complex and it
wasn't trivial to read kernel size.
Fix it by making "kernel" parition contain just a kernel image.

Despite the MS_SILENT flag being set when probing for ubifs rootfs a
logline indicating an error is generated during boot:
UBIFS error (pid: 1): cannot open "ubi0:rootfs", error -19
This leads to confusion and there shouldn't be lines containing
the word 'error' twice in a bootlog if actually everything is fine
(just the rootfs happens to be something else than ubifs)
The patch added has been submitted and was accepted upstream, see:

This can be used to prevent double compression for platforms where the
boot loader already expects compressed images.

The swconfig kernel infrastructure fails to do any permissions checks when
changing settings. As such an ordinary user account on a device with a
switch can change switch settings without any special permissions.
Routers generally have few non-admin users so this isn't a big hole, but it
is a security hole. Likely the greatest danger is for multifunction devices
which have a lot of extra daemons, compromising a low-security daemon would
allow one to modify switch settings and cause the router/switch to appear to
lock-up (or cause other sorts of troublesome nyetwork behavior).
Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any
requests originating from user contexts lacking this capability.

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.
