      Pull i2c updates from Wolfram Sang:

 - bus recovery can now be given a pinctrl handle and the I2C core will
   do all the steps to switch to/from GPIO which can save quite some
   boilerplate code from drivers

 - "fallthrough" conversion

 - driver updates, mostly ID additions

      Linus Torvalds authored 
      Pull more s390 updates from Heiko Carstens:

 - Allow s390 debug feature to handle finally more than 256 CPU numbers,
   instead of truncating the most significant bits.

 - Improve THP splitting required by qemu processes by making use of
   walk_page_vma() instead of calling follow_page() for every single
   page within each vma.

 - Add missing ZCRYPT dependency to VFIO_AP to fix potential compile
   problems.

 - Remove not required select CLOCKSOURCE_VALIDATE_LAST_CYCLE again.

 - Set node distance to LOCAL_DISTANCE instead of 0, since e.g. libnuma
   translates a node distance of 0 to "no NUMA support available".

 - Couple of other minor fixes and improvements.

* tag 's390-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/numa: move code to arch/s390/kernel

      mm: memcontrol: fix warning when allocating the root cgroup · 9f457179
      Johannes Weiner authored 
      Commit 3e38e0aa ("mm: memcg: charge memcg percpu memory to the
parent cgroup") adds memory tracking to the memcg kernel structures
themselves to make cgroups liable for the memory they are consuming
through the allocation of child groups (which can be significant).

This code is a bit awkward as it's spread out through several functions:
The outermost function does memalloc_use_memcg(parent) to set up
current->active_memcg, which designates which cgroup to charge, and the
inner functions pass GFP_ACCOUNT to request charging for specific
allocations.  To make sure this dependency is satisfied at all times -
to make sure we don't randomly charge whoever is calling the functions -
the inner functions warn on !current->active_memcg.

However, this triggers a false warning when the root memcg itself is
allocated.  No parent exists in this case, and so current->active_memcg
is rightfully NULL.  It's a false positive, not indicative of a bug.

Delete the warnings for now, we can revisit this later.

Fixes: 3e38e0aa ("mm: memcg: charge memcg percpu memory to the parent cgroup")
