From: Michael Kelley Date: Wed, 14 Feb 2018 02:54:03 +0000 (+0000) Subject: cpumask: Make for_each_cpu_wrap() available on UP as well X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d207af2eab3f8668b95ad02b21930481c42806fd;p=openwrt%2Fstaging%2Fblogic.git cpumask: Make for_each_cpu_wrap() available on UP as well 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.
