====================
wireless-drivers-next patches for v5.16

Second set of patches for v5.16 and this time we have a big one. We
have the new Realtek driver rtw89 with over 90 kLOC and also over 150
patches for mt76. ath9k also got few new small features. And the usual
cleanups and fixes all over.

Major changes:

rtw89
 * new Realtek 802.11ax driver
 * supports Realtek 8852AE 802.11ax 2x2 chip

ath9k
 * add option to reset the wifi chip via debugfs
 * convert Device Tree bindings to the json-schema
 * support Device Tree ieee80211-freq-limit property to limit channels

mt76
 * mt7921 aspm support
 * mt7921 testmode support
 * mt7915 LED support
 * mt7921 6GHz band support
 * support for eeprom data in DT
 * mt7915 TWT support
 * mt7921s SDIO support

      memblock: exclude MEMBLOCK_NOMAP regions from kmemleak · 658aafc8
      Mike Rapoport authored 
      Vladimir Zapolskiy reports:

Commit a7259df7 ("memblock: make memblock_find_in_range method
private") invokes a kernel panic while running kmemleak on OF platforms
with nomaped regions:

  Unable to handle kernel paging request at virtual address fff000021e00000
  [...]
    scan_block+0x64/0x170
    scan_gray_list+0xe8/0x17c
    kmemleak_scan+0x270/0x514
    kmemleak_write+0x34c/0x4ac

The memory allocated from memblock is registered with kmemleak, but if
it is marked MEMBLOCK_NOMAP it won't have linear map entries so an
attempt to scan such areas will fault.

Ideally, memblock_mark_nomap() would inform kmemleak to ignore
MEMBLOCK_NOMAP memory, but it can be called before kmemleak interfaces
operating on physical addresses can use __va() conversion.

Make sure that functions that mark allocated memory as MEMBLOCK_NOMAP
take care of informing kmemleak to ignore such memory.

Pull ucounts fixes from Eric Biederman:
 "There has been one very hard to track down bug in the ucount code that
  we have been tracking since roughly v5.14 was released. Alex managed
  to find a reliable reproducer a few days ago and then I was able to
  instrument the code and figure out what the issue was.

  It turns out the sigqueue_alloc single atomic operation optimization
  did not play nicely with ucounts multiple level rlimits. It turned out
  that either sigqueue_alloc or sigqueue_free could be operating on
  multiple levels and trigger the conditions for the optimization on
  more than one level at the same time.

  To deal with that situation I have introduced inc_rlimit_get_ucounts
  and dec_rlimit_put_ucounts that just focuses on the optimization and
  the rlimit and ucount changes.

  While looking into the big bug I found I couple of other little issues
  so I am including those fixes here as well.

  When I have time I would very much like to dig into process ownership
  of the shared signal queue and see if we could pick a single owner for
  the entire queue so that all of the rlimits can count to that owner.
  That should entirely remove the need to call get_ucounts and
  put_ucounts in sigqueue_alloc and sigqueue_free. It is difficult
  because Linux unlike POSIX supports setuid that works on a single
  thread"

      Linus Torvalds authored 
      Pull powerpc fixes from Michael Ellerman:

 - Fix a bug exposed by a previous fix, where running guests with
   certain SMT topologies could crash the host on Power8.

 - Fix atomic sleep warnings when re-onlining CPUs, when PREEMPT is
   enabled.

Thanks to Nathan Lynch, Srikar Dronamraju, and Valentin Schneider.
