Merge tag 'cpumask-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux
Pull final removal of deprecated cpus_* cpumask functions from Rusty Russell: "This is the final removal (after several years!) of the obsolete cpus_* functions, prompted by their mis-use in staging. With these function removed, all cpu functions should only iterate to nr_cpu_ids, so we finally only allocate that many bits when cpumasks are allocated offstack" * tag 'cpumask-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (25 commits) cpumask: remove __first_cpu / __next_cpu cpumask: resurrect CPU_MASK_CPU0 linux/cpumask.h: add typechecking to cpumask_test_cpu cpumask: only allocate nr_cpumask_bits. Fix weird uses of num_online_cpus(). cpumask: remove deprecated functions. mips: fix obsolete cpumask_of_cpu usage. x86: fix more deprecated cpu function usage. ia64: remove deprecated cpus_ usage. powerpc: fix deprecated CPU_MASK_CPU0 usage. CPU_MASK_ALL/CPU_MASK_NONE: remove from deprecated region. staging/lustre/o2iblnd: Don't use cpus_weight staging/lustre/libcfs: replace deprecated cpus_ calls with cpumask_ staging/lustre/ptlrpc: Do not use deprecated cpus_* functions blackfin: fix up obsolete cpu function usage. parisc: fix up obsolete cpu function usage. tile: fix up obsolete cpu function usage. arm64: fix up obsolete cpu function usage. mips: fix up obsolete cpu function usage. x86: fix up obsolete cpu function usage. ...
