Johannes Berg says:

====================
Here are quite a large number of fixes, notably:
 * various A-MSDU building fixes (currently only affects mt76)
 * syzkaller & spectre fixes in hwsim
 * TXQ vs. teardown fix that was causing crashes
 * embed WMM info in reg rule, bad code here had been causing crashes
 * one compilation issue with fix from Arnd (rfkill-gpio includes)
 * fixes for a race and bad data during/after channel switch
 * nl80211: a validation fix, attribute type & unit fixes
along with other small fixes.

f623f75ae4 rfkill-gpio: include linux/mod_devicetable.h
One more driver is apparently broken by the recent change
to linux/platform_device.h:

net/rfkill/rfkill-gpio.c: In function 'rfkill_gpio_acpi_probe':
net/rfkill/rfkill-gpio.c:82:29: error: dereferencing pointer to incomplete type 'const struct acpi_device_id'

Include linux/mod_devicetable.h to get the definition of the

2282e125a4 leds: triggers: let struct led_trigger::activate() return an error code
Given that activating a trigger can fail, let the callback return an
indication. This prevents to have a trigger active according to the
"trigger" sysfs attribute but not functional.

All users are changed accordingly to return 0 for now. There is no intended
change in behaviour.

232aa23ec3 rfkill: Create rfkill-none LED trigger
Creates a new trigger rfkill-none, as a complement to rfkill-any, which
drives LEDs when any radio is enabled. The new trigger is meant to turn
a LED ON whenever all radios are OFF, and turn it OFF otherwise.

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

1331b62c97 rfkill: remove rfkill-regulator
There are no users of this ("vrfkill") in the tree, so it's just
dead code - remove it.

This also isn't really how rfkill is supposed to be used - it's
intended as a signalling mechanism to/from the device, which the
driver (and partially cfg80211) will handle - having a separate
rfkill instance for a regulator is confusing, the driver should
use the regulator instead to turn off the device when requested.

9b8e34e211 rfkill: Add rfkill-any LED trigger
Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any,
which may be useful on laptops with a single "radio LED" and multiple
radio transmitters.  The trigger is meant to turn a LED on whenever
there is at least one radio transmitter active and turn it off
otherwise.

7b854982b2 Revert "rfkill: Add rfkill-any LED trigger"
This reverts commit 73f4f76a19.

As Mike reported, and I should've seen in review, we can't call
the new LED functions, which acquire the mutex, from places like
rfkill_set_sw_state() that are documented to be callable from
any context the user likes to use. For Mike's case it led to a
deadlock, but other scenarios are possible.

f6b4122c93 rfkill: hide unused goto label
A cleanup introduced a harmless warning in some configurations:

net/rfkill/core.c: In function 'rfkill_init':
net/rfkill/core.c:1350:1: warning: label 'error_input' defined but not used [-Wunused-label]

This adds another #ifdef around the label to match that around the
caller.

Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any,
which may be useful on laptops with a single "radio LED" and multiple
radio transmitters.  The trigger is meant to turn a LED on whenever
there is at least one radio transmitter active and turn it off
otherwise.

This requires taking rfkill_global_mutex before calling rfkill_set_block()
in rfkill_resume(): since __rfkill_any_led_trigger_event() is called from
rfkill_set_block() unconditionally, each caller of the latter needs to
take care of locking rfkill_global_mutex.
