Subject: [PATCH 00/21] add coccinelle scripts for {bitmap,cpumask,nodes}_empty()

In this series:
 - introduce bitmap.cocci, cpumask.cocci and nodemask.cocci;
 - add checks for cases where bitmap_weight() may be replaced with one of
   "empty, full, gt, lt, ge, le or eq" versions; and
 - address issued found with those scripts.

On top of next-2022-05-06.

Yury Norov (22):
  introduce bitmap.cocci
  introduce cpumask.cocci
  introduce nodemask.cocci
  ice: use bitmap_empty() in ice_vf_has_no_qs_ena()
  iio: replace bitmap_weight with bitmap_weitght_{eq,le} where
    appropriate
  octeontx2: use bitmap_empty() instead of bitmap_weight()
  risc-v: replace bitmap_weight with bitmap_empty in riscv_fill_hwcap()
  bitops: introduce MANY_BITS() macro
  qed: replace bitmap_weight() with MANY_BITS()
  net/mlx5e: simplify mlx5e_set_fecparam()
  KVM: x86: hyper-v: replace bitmap_weight() with hweight64()
  ia64: cleanup remove_siblinginfo()
  x86: smp: move cpumask_weight() out of for-loop in remove_siblinginfo
  x86: smp: use cpumask_weight_eq() in remove_siblinginfo
  net/mlx5: use cpumask_weight_gt() in irq_pool_request_irq()
  x86/tsc: use cpumask_weight_gt() in loop_timeout()
  sched/core: fix opencoded cpumask_any_but() in
    sched_core_cpu_{starting,deactivate}
  sched/core: remove unneeded cpumask_weight in
    sched_core_cpu_{starting,deactivate}
  sched/core: replace cpumask_weight() with cpumask_weight_eq() where
    appropriate
  sched/topology: replace cpumask_weight() with cpumask_weight_eq where
    appropriate
  cpufreq: use cpumask_weight_gt() in policy_is_shared()
  clockevents: use cpumask_weight_eq() in tick_cleanup_dead_cpu()
