#     Merge tag 'bitmap-6.1-rc1' of https://github.com/norov/linux
#     
#     Pull bitmap updates from Yury Norov:
#     
#      - Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES (Phil Auld)
#     
#      - cleanup nr_cpu_ids vs nr_cpumask_bits mess (me)
#     
#        This series cleans that mess and adds new config FORCE_NR_CPUS that
#        allows to optimize cpumask subsystem if the number of CPUs is known
#        at compile-time.
#     
#      - optimize find_bit() functions (me)
#     
#        Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT()
#        macros.
#     
#      - add find_nth_bit() (me)
#     
#        Adds find_nth_bit(), which is ~70 times faster than bitcounting with
#        for_each() loop:
#     
#             for_each_set_bit(bit, mask, size)
#                     if (n-- == 0)
#                             return bit;
#     
#        Also adds bitmap_weight_and() to let people replace this pattern:
#     
#             tmp = bitmap_alloc(nbits);
#             bitmap_and(tmp, map1, map2, nbits);
#             weight = bitmap_weight(tmp, nbits);
#             bitmap_free(tmp);
#     
#        with a single bitmap_weight_and() call.
#     
#      - repair cpumask_check() (me)
#     
#        After switching cpumask to use nr_cpu_ids, cpumask_check() started
#        generating many false-positive warnings. This series fixes it.
#     
#      - Add for_each_cpu_andnot() and for_each_cpu_andnot() (Valentin
#        Schneider)
#     
#        Extends the API with one more function and applies it in sched/core.
