e545808e89 ar71xx: Fix potentially missed IRQ handling during dispatch
If both interrupts are set in the current implementation
only the 1st will be handled and the 2nd will be skipped
due to the "if else" condition.

Fix this by using the same approach as done for QCA955x
just below it.

5dbac47426 kernel: re-add bridge allow reception on disabled port
The "bridge allow reception on disabled port" implementation
was broken after these commits:

b765f4be40 ("kernel: bump 4.14 to 4.14.114")
456f486b53 ("kernel: bump 4.9 to 4.9.171")

This leads to issues when for example WDS is used, tied to a bridge:

[ 96.503771] wlan1: send auth to d4:5f:25:eb:09:82 (try 1/3)
[ 96.517956] wlan1: authenticated
[ 96.526209] wlan1: associate with d4:5f:25:eb:09:82 (try 1/3)

[ 97.200919] wlan1: RX AssocResp from d4:5f:25:eb:09:82 (capab=0x11 status=0 aid=1)

[ 101.312913] wlan1: deauthenticated from d4:5f:25:eb:09:82 (Reason: 2=PREV_AUTH_NOT_VALID)

It seems upstream introduced a new patch, [1]
so we have to reimplement these patches properly:

target/linux/generic/pending-4.9/150-bridge_allow_receiption_on_disabled_port.patch
target/linux/generic/pending-4.14/150-bridge_allow_receiption_on_disabled_port.patch

afcdf099b7 kernel: fix f2fs on big endian machines
The WD MyBook Live SquashFS images didn't work anymore due to
a upstream regression in f2fs commit: 0cfe75c5b01199
("f2fs: enhance sanity_check_raw_super() to avoid potential overflows")
that got backported to 4.14.86 and 4.9.144.

by Martin Blumenstingl:
|Treat "block_count" from struct f2fs_super_block as 64-bit little endian
|value in sanity_check_raw_super() because struct f2fs_super_block
|declares "block_count" as "__le64".
|
|This fixes a bug where the superblock validation fails on big endian
|devices with the following error:
|  F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0)
|  F2FS-fs (sda1): Can't find valid F2FS filesystem in 1th superblock
|  F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0)
|  F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock
|As result of this the partition cannot be mounted.
|
|With this patch applied the superblock validation works fine and the
|partition can be mounted again:
|  F2FS-fs (sda1): Mounted with checkpoint version = 7c84
|
|My little endian x86-64 hardware was able to mount the partition without
|this fix.
|To confirm that mounting f2fs filesystems works on big endian machines
|again I tested this on a 32-bit MIPS big endian (lantiq) device.

Hopefully, this will do until Martin's patch moved through upstream
to -stable.

031d5cf248 kernel: don't auto attach ubi on read error
With a10a204aab ("kernel: make ubi auto-attach check for a tar file
magic") the check for the magic was added without considering a failing
mtd_read(). If the read fails, no check is done and the mount code is
called straight away.

Failing with an error message for such cases seems to me the cleaner way,
as it would allow to spot hidden/workaround issues.

edc2af2be9 kernel: improve ubi auto attach code readability
Move the put_mtd_device() called on multiple error conditions to a goto
label to use it later for more error conditions.

The early return on failed open of the mtd device and mismatching mtd
type allows to get rid of one level of indentation. By jumping to the
cleanup code, a refcount bug is fixed for the wrong flash type condition.

While at it, make clear that we only check for the UBI magic if the read
from flash was successful.

This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).

It's required to successfully backport support for new devices using
that new syntax in their DT files.

Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

f7668334a8 Re-enable arbitrary IPv6 addresses as outer ip4-in-ip6 tunnel source address
The 666-Add-support-for-MAP-E-FMRs-mesh-mode.patch kernel patches
break the possibility for using an ip4ip6 tunnel interface as a fall
back interface accepting ip4-in-ip6 tunneled packets from any remote
address. This works out of the box with any normal (non-666-patched)
kernel and can be configured by setting up an 'ip -6 tunnel' with type
'any' or 'ip4ip6' and a remote address of '::'.

The misbehavior comes with line 290 the patch which discards all packets
that do not show the expected saddr, even if no single fmr rule was
defined and despite the validity of the saddr was already approved earlier.

d700eb187b kernel: remove duplicate #define's in at803x Ethernet PHY driver
AT803X_REG_CHIP_CONFIG and AT803X_BT_BX_REG_SEL have been defined
upstream by commit f62265b53ef3 ("at803x: double check SGMII side autoneg")
An existing local patch then added those exact same defines again which
isn't necessary, so remove them.

20c64dabb6 kernel: re-add patch for AT8032 Ethernet PHY
The patch was wrongly removed by a kernel version bump to 4.9.106 in
the believe that it was merged upstream thow it wasn't. This lead to
unrecoverable link losses on devices which use those PHYs such as
many ubnt single-port CPEs.

3e81365141 kernel: gen_stats: Fix netlink stats dumping in the presence of padding
Backport hot off the press upstream netlink patch.  Fixes stats display
from CAKE qdisc on MIPS allowing us to bump CAKE to latest version.

The gen_stats facility will add a header for the toplevel nlattr of type
TCA_STATS2 that contains all stats added by qdisc callbacks. A reference
to this header is stored in the gnet_dump struct, and when all the
per-qdisc callbacks have finished adding their stats, the length of the
containing header will be adjusted to the right value.

However, on architectures that need padding (i.e., that don't set
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added
before the stats, which means that the stored pointer will point to the
padding, and so when the header is fixed up, the result is just a very
big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS
struct, this problem has been mostly invisible, but we exposed it with
the netlink attribute-based statistics in CAKE.

Fix the issue by fixing up the stored pointer if it points to a padding
nlattr.
