Merge tag 'bitmap-for-7.3' of https://github.com/norov/linux

Pull bitmap updates from Yury Norov:
 "The usual set of fixes, cleanups and performance improvements together
  with a couple of new tests:

   - bitmap_find_next_zero_area_off() optimization (Sunyi)

   - bitmap_find_next_zero_area_off(): return size when no zero area is
     found (Yury)

   - bitmap vs IDA vs Maple Tree performance test (Yury)

   - get rid of cpumap_print_to_pagebuf() (Yury)

   - use nr_node_ids in __nodemask_pr_numnodes() (Li RongQing)

   - bitops: make the *_bit_le functions use unsigned long (Benjamin)

   - bitmap scatter & gather test fix (Christophe)

   - use __ASSEMBLER__ in bitmap header files (Thomas)"
