Subject: lib/cpumask.c: remove __any_online_cpu()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=38b93780a5381961ad92d24ab9a12a964189a3a4;p=openwrt%2Fstaging%2Fblogic.git

lib/cpumask.c: remove __any_online_cpu()

__any_online_cpu() is not optimal and also unnecessary.  So, replace its
use by faster cpumask_* operations.
