V2 of "[PATCH 0/2] mm: memcontrol: cleanup and optimize for accounting params".

Patch 1/2 is a minor cleanup for kmem accouting path.

Patch 2/2 optimizes some hot paths by making cgroup_memory_noswap a
static key, benchmark shows swap paths now have a ~5% lower overhead.

Update from V1:
- Collect Acked-by for patch 2/2 from Michal Hocko, Thanks!
- Simplify patch 1/1, don't drop mem_cgroup_kmem_disabled and only
change one call site as a minor clean up, update commit message
for patch 2/2, as suggested by Michal Hocko.

Kairui Song (2):
mm: memcontrol: use memcg_kmem_enabled in count_objcg_event
mm: memcontrol: make cgroup_memory_noswap a static key
