[PATCH 0/5] cpumask: Use cpumask_intersects* APIs where applicable

[Shrikanth Hegde]

It was observed while working on cpumask_intersects_and, check like
below could use it instead.

if (cpumask_first_and_and() < nr_cpu_ids)

While there, did check the code for any such similar patterns of
cpumask_any_and, cpumask_first_and and explicit loops where
cpu found by these APIs are not being used. All those callsites
instead can simply use cpumask_intersects.

Note that few more places can use similar change. But, I have left
them as is. 
drivers/net/ethernet/sfc/efx_channels.c+370
drivers/net/ethernet/sfc/siena/efx_channels.c+371
drivers/platform/x86/intel/uncore-frequency/uncore-frequency.c+153

Also, these patches can combined into three patches if that is
easier for review/merge. I have kept it separate since they belong
to different subsystems.
