Subject: [PATCH 4.9 101/329] cpumask: Make for_each_cpu_wrap() available on UP as well
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Kelley <mhkelley@...look.com>
[ Upstream commit d207af2eab3f8668b95ad02b21930481c42806fd ]
for_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.
