Merge branch 'for-5.2' of git://git./linux/kernel/git/dennis/percpu

Pull percpu updates from Dennis Zhou:

 - scan hint update which helps address performance issues with heavily
   fragmented blocks

 - lockdep fix when freeing an allocation causes balance work to be
   scheduled

* 'for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu:
  percpu: remove spurious lock dependency between percpu and sched
  percpu: use chunk scan_hint to skip some scanning
  percpu: convert chunk hints to be based on pcpu_block_md
  percpu: make pcpu_block_md generic
  percpu: use block scan_hint to only scan forward
  percpu: remember largest area skipped during allocation
  percpu: add block level scan_hint
  percpu: set PCPU_BITMAP_BLOCK_SIZE to PAGE_SIZE
  percpu: relegate chunks unusable when failing small allocations
  percpu: manage chunks based on contig_bits instead of free_bytes
  percpu: introduce helper to determine if two regions overlap
  percpu: do not search past bitmap when allocating an area
  percpu: update free path with correct new free region
