From: Peter Zijlstra peterz@infradead.org
[ Upstream commit c743f0a5c50f2fcbc628526279cfa24f3dabe182 ]
More users for for_each_cpu_wrap() have appeared. Promote the construct to generic cpumask interface.
The implementation is slightly modified to reduce arguments.

cpumask: Make for_each_cpu_wrap() available on UP as wellfor_each_cpu_wrap() was originally added in the #else half of a large "#if NR_CPUS == 1" statement, but was omitted in the #if half. This patch adds the missing #if half to prevent compile errors when NR_CPUS is 1.
