[PATCH 0/4] [RFC] cpumask: Robustify the var-cpumask allocation APIs

[Ingo Molnar]

Hi Rusty,

this is the cpumask API robustification change we talked about in this
lkml thread:

  [PATCH] sched/core: Clear the root_domain cpumasks in init_rootdomain()

The idea is to first migrate all users of alloc_cpumask_var() to
zalloc_cpumask_var(), then remove the old API.

We still keep __alloc_cpumask_var_node(), for users who absolutely want
to micro-manage their cpumask allocations.

I also addressed a related naming ambiguity in alloc_bootmem_cpumask_var().

Lightly tested.

( If you like this series I can merge it via -tip, or you can pick it up,
  your call! )

Thanks,

	Ingo
