Merge branch 'for-5.2' of git://git.kernel.org/pub/scm/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
