Merge tag 'bitmap-for-5.19-rc1' of https://github.com/norov/linux
Pull bitmap updates from Yury Norov: - bitmap: optimize bitmap_weight() usage, from me - lib/bitmap.c make bitmap_print_bitmask_to_buf parseable, from Mauro Carvalho Chehab - include/linux/find: Fix documentation, from Anna-Maria Behnsen - bitmap: fix conversion from/to fix-sized arrays, from me - bitmap: Fix return values to be unsigned, from Kees Cook It has been in linux-next for at least a week with no problems. * tag 'bitmap-for-5.19-rc1' of https://github.com/norov/linux: (31 commits) nodemask: Fix return values to be unsigned bitmap: Fix return values to be unsigned KVM: x86: hyper-v: replace bitmap_weight() with hweight64() KVM: x86: hyper-v: fix type of valid_bank_mask ia64: cleanup remove_siblinginfo() drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate KVM: s390: replace bitmap_copy with bitmap_{from,to}_arr64 where appropriate lib/bitmap: add test for bitmap_{from,to}_arr64 lib: add bitmap_{from,to}_arr64 lib/bitmap: extend comment for bitmap_(from,to)_arr32() include/linux/find: Fix documentation lib/bitmap.c make bitmap_print_bitmask_to_buf parseable MAINTAINERS: add cpumask and nodemask files to BITMAP_API arch/x86: replace nodes_weight with nodes_empty where appropriate mm/vmstat: replace cpumask_weight with cpumask_empty where appropriate clocksource: replace cpumask_weight with cpumask_empty in clocksource.c genirq/affinity: replace cpumask_weight with cpumask_empty where appropriate irq: mips: replace cpumask_weight with cpumask_empty where appropriate drm/i915/pmu: replace cpumask_weight with cpumask_empty where appropriate arch/x86: replace cpumask_weight with cpumask_empty where appropriate ...
