94a1fedd63 libbpf: Add btf__parse_raw() and generic btf__parse() APIs
Add public APIs to parse BTF from raw data file (e.g.,
/sys/kernel/btf/vmlinux), as well as generic btf__parse(), which will try to
determine correct format, currently either raw or ELF.

f8c11eb7da ALSA: usb-audio: Add support for Lenovo ThinkStation P620
Lenovo ThinkStation P620 is like other TRX40 boards, is equipped with
two USB audio cards.

USB device (17aa:104d) provides functionality for Internal Speaker and
Front Headset. It's UAC v2, so it supports insertion control (jack
detection). However, when trying to get the connector status of the
speaker, an error occurs:
[    5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0

Since the insertion control works perfectly for the headset, the error
for speaker is probably casued by connecting internally. So let's relax
the error for a bit if it's a speaker, and always reports it's connected.

USB device (17aa:1046) is for rear Line-in, Line-out and Microphone.
The insertion control works for all three jacks. However, there's an
Function Unit that doesn't work:
[    5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4
[    5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19)

So turn off the FU to avoid the error.

Also, add specific card name for both devices, so userspace can easily
indentify both cards.

caecb05c80 PCI: Remove dev_err() when handing an error from platform_get_irq()
There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq() or
platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.

This change is as per suggestions from Coccinelle, e.g.,

  drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is
  redundant because platform_get_irq() already prints an error

a278f3d819 tools, build: Propagate build failures from tools/build/Makefile.build
The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with
non-zero effect: the command failure is masked (despite `set -e`) and all but
the first command of $(dep-cmd) is executed (successfully, as they are mostly
printfs), thus overall returning 0 in the end.

This means in practice that despite compilation errors, tools's build Makefile
will return success. We see this very reliably with libbpf's Makefile, which
doesn't get compilation error propagated properly. This in turns causes issues
with selftests build, as well as bpftool and other projects that rely on
building libbpf.

The fix is simple: don't use &&. Given `set -e`, we don't need to chain
commands with &&. The shell will exit on first failure, giving desired
behavior and propagating error properly.

0dcd3c94e0 erofs: fix extended inode could cross boundary
Each ondisk inode should be aligned with inode slot boundary
(32-byte alignment) because of nid calculation formula, so all
compact inodes (32 byte) cannot across page boundary. However,
extended inode is now 64-byte form, which can across page boundary
in principle if the location is specified on purpose, although
it's hard to be generated by mkfs due to the allocation policy
and rarely used by Android use case now mainly for > 4GiB files.

For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't
be read from disk properly and cause out-of-bound memory read
with random value.

Let's fix now.

  - Add a helper for getting the RTD from a substream.
  - Many, many fixes and cleanups to the x86 code.

54212f5a1b leds: add RGB color option, as that is different from multicolor.
Multicolor is a bit too abstract. Yes, we can have
Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
RGB, and not even RGB-White or RGB-Yellow variants emerged.

Multicolor is not a good fit for RGB LED. It does not really know
about LED color.  In particular, there's no way to make LED "white".

Userspace is interested in knowing "this LED can produce arbitrary
color", which not all multicolor LEDs can.

0b91111fb1 mac80211: Do not report beacon loss if beacon filtering enabled
mac80211.h says: Beacon filter support is advertised with the
IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to
enable beacon filter support whenever power save is enabled, that is
IEEE80211_CONF_PS is set. When power save is enabled, the stack will
not check for beacon loss and the driver needs to notify about loss
of beacons with ieee80211_beacon_loss().

Some controllers may want to dynamically enable the beacon filter
capabilities on power save entry (CONF_PS) and disable it on exit.
This is the case for the wcn36xx driver which only supports beacon
filtering in PS mode (no CONNECTION_MONITOR support).

When the mac80211 beacon monitor timer expires, the beacon filter
flag must be checked again in case it as been changed in between
(e.g. vif moved to PS mode).

4203b19c27 netfilter: flowtable: Set offload timeout when adding flow
On heavily loaded systems the GC can take time to go over all existing
conns and reset their timeout. At that time other calls like from
nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as
expired. To fix this when we set the offload bit we should also reset
the timeout instead of counting on GC to finish first iteration over
all conns before the initial timeout.

4e56cde15f mac80211: Handle special status codes in SAE commit
SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK
(WFA) options. Those extensions use special status code values in the
SAE commit messages (Authentication frame with transaction sequence
number 1) to identify which extension is in use. mac80211 was
interpreting those new values as the AP denying authentication and that
resulted in failure to complete SAE authentication in some cases.

Fix this by adding exceptions for the new status code values 126 and
127.

45a4d8fd6c md/raid5: Allow degraded raid6 to do rmw
Degraded raid6 always do reconstruct-write now. With raid6 xor supported,
we can do rmw in degraded raid6. This patch can reduce many read IOs to
improve performance.

If the failed disk is P, Q or the disk we want to write to, we may need to
do reconstruct-write in max degraded raid6. In this situation we can not
read enough data from handle_stripe_dirtying() so we have to set force_rcw
in handle_stripe_fill() to read all data.

a1c6ae3d9f md/raid5: Fix Force reconstruct-write io stuck in degraded raid5
In degraded raid5, we need to read parity to do reconstruct-write when
data disks fail. However, we can not read parity from
handle_stripe_dirtying() in force reconstruct-write mode.

Reproducible Steps:

1. Create degraded raid5
mdadm -C /dev/md2 --assume-clean -l5 -n3 /dev/sda2 /dev/sdb2 missing
2. Set rmw_level to 0
echo 0 > /sys/block/md2/md/rmw_level
3. IO to raid5

Now some io may be stuck in raid5. We can use handle_stripe_fill() to read
the parity in this situation.

This reverts commit dfd74a1edf.

This has been fixed by commit dca4436d1c which added the out
of bounds check to __add_memory, so that trying to add blocks past
MAX_PHYSMEM_BITS will fail.

Note the check in the Xen balloon driver was bogus anyway, as it
checked the start address of the resource, but it should instead test
the end address to assert the whole resource falls below
MAX_PHYSMEM_BITS.
