Subject: [PATCH 0/8] Cleanup and optimization patches for percpu

These were found out when reading percpu code, and queued in my local
branch for long time. Send them out for reviewing.

Baoquan He (8):
  mm/percpu: remove unused pcpu_map_extend_chunks
  mm/percpu: use list_first_entry_or_null in pcpu_reclaim_populated()
  mm/percpu: Update the code comment when creating new chunk
  mm/percpu: add comment to state the empty populated pages accounting
  mm/percpu: replace the goto with break
  mm/percpu.c: remove the lcm code since block size is fixed at page
    size
  mm/percpu: remove unused PERCPU_DYNAMIC_EARLY_SLOTS
  mm/slub, percpu: correct the calculation of early percpu allocation
    size
