Subject: [PATCH 0/7] RDMA: hfi1: cpumasks usage fixes

The driver uses cpumasks API in a non-optimal way; partially because of
absence of proper functions. Fix this and nearby logic.

Yury Norov [NVIDIA] (7):
  cpumask: add cpumask_clear_cpus()
  RDMA: hfi1: fix possible divide-by-zero in find_hw_thread_mask()
  RDMA: hfi1: simplify find_hw_thread_mask()
  RDMA: hfi1: simplify init_real_cpu_mask()
  RDMA: hfi1: use rounddown in find_hw_thread_mask()
  RDMA: hfi1: simplify hfi1_get_proc_affinity()
  RDMI: hfi1: drop cpumask_empty() call in hfi1/affinity.c
