Currently it's not possible to use perf on ath79 due to genirq flags
mismatch happening on static virtual IRQ 13 which is used for
performance counters hardware IRQ 5.

$ perf top
genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1)
This problem is happening, because currently statically assigned virtual
IRQ 13 for performance counters is not claimed during the initialization
of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
this interrupt isn't available for further use.
So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

Many MIPS CPUs have optional CPU features which are not activates for
all CPU cores. Print the CPU options which are implemented in the core
in /proc/cpuinfo. This makes it possible to see what features are
supported and which are not supported. This should cover all standard
MIPS extensions, before it only printed information about the main MIPS
ASEs.

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 landed in 4.18.
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.

This patch, in a variety of forms, has been around since beginning 2016
as e756c2bb07, ending up in present form 0aa6c7df60 (kernel 4.4.13 bump)
and carried forward ever since.
There have been a number of MIPS kernel memory handling changes since,
including VDSO fixes that meant openwrt patches have been dropped with
no apparent fallout.
Simple tests (ntfs-3g) on a HIGHMEM 512MB mt7621 device have not turned
up data corruption issues which would otherwise be expected. Similarly
running on other MIPS based devices for the past 2 months hasn't turned
up anything obvious to retain this out of tree patch.
With thanks to Rosen Penev for testing on the known 'highmem' device and
Felix Fietkau for testing advice. Not putting acked-by as it's my fault
if it breaks :-)

I've sent this one upstream. This patch is critical if you want to run
with "prove lock correctness" (lockdep) and you happen to have certain
mtd devices. The misuse of the uninitialized object is undefined
behaviour, but being zeroed it does not appear to have actually broken
anything other than the lockdep engine.

The ledtrig-netdev was added to upstream Linux kernel 4.16, replace our
own version with the patch based on the upstream version.
This will remove the ledtrig-netdev support from kernel 3.18, because I
not want to spend time on backporting it to 3.18. This will make it
easier to use the upstream version with kernel 4.19, by just not
applying this patch.

This reverts commit 7e88753ace.
Using subpartitions (hierarchical layout) resulted in calling MTD ops of
parent partition instead of master device ops. That was expected and
should work but testing revealed some bugs.
Apparently the way MTD_ERASE_PARTIAL is implemented in the OpenWrt
breaks something and using parent partition ops triggers using that
code.
On SmartRG SR400ac it was resulting in:
[ 225.487519] jffs2: Erase at 0x01ac0000 failed immediately: errno -22
on the second boot (for some reason erasing was starting over) and it
was breaking flash access in a long term.

This helper uses hierarchical partitions layout following the way
upstream parsers work. It's closer to what we should use when mainlining
our solutions. It also doesn't require hacky casting of struct
mtd_partition to the const.
THIS WILL AFFECT KERNEL PRINTING PARTITIONS IN THE LOG
Something like:
[ 3.930158] 0x0000004e0000-0x000001fb0000 : "rootfs_data"
will get replaced by:
[ 3.907338] Creating 1 MTD partitions on "rootfs":
[ 3.912142] 0x00000031d400-0x000001ded400 : "rootfs_data"
It's important to understand that "rootfs_data" in above example is a
*subpartition* of the "rootfs" now. To get absolute addresses (e.g. for
some debugging purposes) one has to add them to the "rootfs", e.g.
[ 3.912548] 0x0000001c2c00-0x000001fb0000 : "rootfs"
(0x1c2c00 + 0x31d400 = 0x4e0000)

If "compatible" is being used that should trigger a proper parser
directly. It's more reliable thanks to not trying parsers one by one. In
such case partition shouldn't be split automatically to avoid parsing it
twice.

It makes more sense to add run_parsers_by_type() in a patch that
introduces parser types. That makes the other one just add a code using
it.

It has been rejected upstream and instead a nice/more generic solution
has been implemented. It's possible now to describe partitions format
using "compatible" DT string.
No OpenWrt target uses "linux,part-probe" anymore, leave it only in case
some forks need it. It will be dropped with support for new kernels.

Newer batches of several Mikrotik boards contain this yet-unsupported
flash chip, for instance:

Commit b7265c59ab ("kernel: backport a series of netfilter cleanup
patches to 4.14") added patch 302-netfilter-nf_tables_inet-don-t-use-
multihook-infrast.patch. That patch switches the netfilter core in the
kernel to use the new native NFPROTO_INET support. Unfortunately, the
new native NFPROTO_INET support does not exist in 4.14 and was not
backported along with this patchset. As such, nftables inet tables never
see any traffic.
As an example the following nft counter rule should increment for every
packet coming into the box, but never will:
nft add table inet foo
nft add chain inet foo bar { type filter hook input priority 0\; }
nft add rule inet foo bar counter
This commit pulls in the required backport patches to add the new
native NFPROTO_INET support, and thus restore nftables inet table
functionality.

Some systems require multiple flash chips to be concatenated and read as
a single mtd device. The ar71xx target provides custom code to create
such mtdconcat devices. When porting devices to ath79, however, there is
no way to create such devices from within the device tree.
This commit adds a driver for creating virtual mtd-concat devices to the
ath79 target. Nodes must have a compatible = "virtual,mtd-concat" line,
and define a list of devices to concat in the 'devices' property,
for example:
flash {
compatible = "virtual,mtd-concat";
devices = <&flash0 &flash1>;
};
The driver is added to the very end of the mtd Makefile to increase the
likelyhood of all child devices already being loaded at the time of
probing, preventing unnecessary deferred probes which might in turn
cause other problems (like failure to load MAC addresses from art because
the partitions are not loaded yet).
