Subject: [IA64] another place to use for_each_cpu_mask() in arch/ia64
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ddf6d0a00cbb4ad6d4fb4200cc911bb9389174c1;p=openwrt%2Fstaging%2Fblogic.git

[IA64] another place to use for_each_cpu_mask() in arch/ia64

In arch/ia64 change the explicit use of a for-loop using NR_CPUS into the
general for_each_online_cpu() construct.  This widens the scope of potential
future optimizations of the general constructs, as well as takes advantage
of the existing optimizations of first_cpu() and next_cpu(), which is
advantageous when the true CPU count is much smaller than NR_CPUS.
