With that patch in place for initramfs no additional options are
reported for "/" partition. What's really important is missing
info about sizes. Which in its turn makes opkg think that there's
no space on "/" partition to install software.
I understand that's a sort of corner-case, people rarely install
packages on ramfs but anyways why not?
Just in case that's what I see with the patch:
---------------------->8--------------------
root@lede:/# cat /proc/mounts
rootfs / rootfs rw 0 0
proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
debugfs /sys/kernel/debug debugfs rw,noatime 0 0
---------------------->8--------------------
And without:
---------------------->8--------------------
root@lede:/# cat /proc/mounts
rootfs / rootfs rw,size=256168k,nr_inodes=32021 0 0
proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
debugfs /sys/kernel/debug debugfs rw,noatime 0 0
---------------------->8--------------------
Note how different is entry for rootfs.
And given there's no known rationale for that patch we're
getting rid of it.

This patch is a backport for current LEDE 4.4 Kernels.
It is already upstream, for linux-next and stable.
The initial commit message is below:
The bridge is falsly dropping ipv6 mulitcast packets if there is:
1. No ipv6 address assigned on the brigde.
2. No external mld querier present.
3. The internal querier enabled.
When the bridge fails to build mld queries, because it has no
ipv6 address, it slilently returns, but keeps the local querier enabled.
This specific case causes confusing packet loss.
Ipv6 multicast snooping can only work if:
a) An external querier is present
OR
b) The bridge has an ipv6 address an is capable of sending own queries
Otherwise it has to forward/flood the ipv6 multicast traffic,
because snooping cannot work.
This patch fixes the issue by adding a flag to the bridge struct that
indicates that there is currently no ipv6 address assinged to the bridge
and returns a false state for the local querier in
__br_multicast_querier_exists().
Special thanks to Linus Lüssing.

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.

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:

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

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

This is often because memblock_insert_region.isra.1 lacks a __meminit
