+Subject: cpumask: Make for_each_cpu_wrap() available on UP as well
+
+From: Michael Kelley <mhkelley@outlook.com>
+
+commit d207af2eab3f8668b95ad02b21930481c42806fd upstream.
+
+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.
