The x86, arm, and arm64 asm implementations of crct10dif are very
difficult to understand partly because many of the comments, labels, and
macros are named incorrectly: the lengths mentioned are usually off by a
factor of two from the actual code. Many other things are unnecessarily
convoluted as well, e.g. there are many more fold constants than
actually needed and some aren't fully reduced.
This series therefore cleans up all these implementations to be much
more maintainable. I also made some small optimizations where I saw
opportunities, resulting in slightly better performance.
This patch cleans up the arm64 version.

This patch cleans up the x86 version.
As part of this, I removed support for len < 16 from the x86 assembly;
now the glue code falls back to the generic table-based implementation
in this case. Due to the overhead of kernel_fpu_begin(), this actually
significantly improves performance on these lengths. (And even if
kernel_fpu_begin() were free, the generic code is still faster for about
len < 11.) This removal also eliminates error-prone special cases and
makes the x86, arm32, and arm64 ports of the code match more closely.

A kexec reboot may leave the firmware in INIT or WORKING state.
Currently, we issue PLATFORM_INIT command during the probe without
checking the current state. The PLATFORM_INIT command fails if the
FW is already in INIT state. Lets check the current state, if FW
is not in UNINIT state then transition it to UNINIT before
initializing or upgrading the FW.

We were enabling autosuspend, which is using data set by the
hash module, prior to the hash module being inited, casuing
a crash on resume as part of the startup sequence if the race
was lost.
This was never a real problem because the PM infra was using low
res timers so we were always winning the race, until commit 8234f6734c5d
("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-)
Fix this by seperating the PM setup and enablement and doing the
latter only at the end of the init sequence.

The kernel verifier has three levels of logs:
0: no logs
1: logs mostly useful
> 1: verbose
Current libbpf API functions bpf_load_program_xattr() and
bpf_load_program() cannot specify log_level.
The bcc, however, provides an interface for user to
specify log_level 2 for verbose output.
This patch added log_level into structure
bpf_load_program_attr, so users, including bcc, can use
bpf_load_program_xattr() to change log_level. The
supported log_level is 0, 1, and 2.
The bpf selftest test_sock.c is modified to enable log_level = 2.
If the "verbose" in test_sock.c is changed to true,
the test will output logs like below:
$ ./test_sock
func#0 @0
0: R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1
0: (bf) r6 = r1
1: R1=ctx(id=0,off=0,imm=0) R6_w=ctx(id=0,off=0,imm=0) R10=fp0,call_-1
1: (61) r7 = *(u32 *)(r6 +28)
invalid bpf_context access off=28 size=4
Test case: bind4 load with invalid access: src_ip6 .. [PASS]
...
Test case: bind6 allow all .. [PASS]
Summary: 16 PASSED, 0 FAILED
Some test_sock tests are negative tests and verbose verifier
log will be printed out as shown in the above.

Let genphy_c45_read_link manage the devices to check, this removes
overhead from callers. Add C22EXT to the list of excluded devices
because it doesn't implement the status register. According to the
802.3 clause 45 spec registers 29.0 - 29.4 are reserved.
At the moment we have very few clause 45 PHY drivers, so we are
lacking experience whether other drivers will have to exclude further
devices, or may need to check PHY XS. If we should figure out that
list of devices to check needs to be configurable, I think best will
be to add a device list member to struct phy_driver.
v2:
- adjusted commit message
- exclude also device C22EXT from link checking

Commit ed75986f4aae ("net/smc: ipv6 support for smc_diag.c") changed the
value of the diag_family field. The idea was to indicate the family of
the IP address in the inet_diag_sockid field. But the change makes it
impossible to distinguish an inet_sock_diag response message from SMC
sock_diag response. This patch restores the original behaviour and sends
AF_SMC as value of the diag_family field.

If SMC client and server connections are both established at the same
time, smc_connect_rdma() cannot send a CLC confirm message while
smc_listen_work() is waiting for one due to lock contention. This can
result in timeouts in smc_clc_wait_msg() and failed SMC connections.
In case of SMC-R, there are two types of LGRs (client and server LGRs)
which can be protected by separate locks. So, this patch splits the LGR
pending lock into two separate locks for client and server to avoid the
locking issue for SMC-R.

On my Yeeloong 8089, I noticed the machine fails to shutdown
properly, and often, the function mach_prepare_reboot() is
unexpectedly executed, thus the machine reboots instead. A
wait loop is needed to ensure the system is in a well-defined
state before going down.
In commit 997e93d4df16 ("MIPS: Hang more efficiently on
halt/powerdown/restart"), a general superset of the wait loop for all
platforms is already provided, so we don't need to implement our own.
This commit simply removes the unreachable() compiler marco after
mach_prepare_reboot(), thus allowing the execution of machine_hang().
My test shows that the machine is now able to shutdown successfully.
Please note that there are two different bugs preventing the machine
from shutting down, another work-in-progress commit is needed to
fix a lockup in cpufreq / i8259 driver, please read Reference, this
commit does not fix that bug.

The commit a60945fd08e4 ("ALSA: usb-audio: move implicit fb quirks to
separate function") introduced an error in the handling of quirks for
implicit feedback endpoints. This commit fixes this.
If a quirk successfully sets up an implicit feedback endpoint, usb-audio
no longer tries to find the implicit fb endpoint itself.

Hangbin Liu says:
====================
fix two kernel panics when disabled IPv6 on boot up
When disabled IPv6 on boot up, since there is no ipv6 route tables, we should
not call rt6_lookup. Fix them by checking if we have inet6_dev pointer on
netdevice.
v2: Fix idev reference leak, declarations and code mixing as Stefano,
Eric pointed. Since we only want to check if idev exists and not
reference it, use __in6_dev_get() insteand of in6_dev_get().
