Subject: ia64: make cpu_callin_map non-volatile.
X-Git-Tag: omap-for-v4.2/wakeirq-drivers-v2^2~2^2~23^2

ia64: make cpu_callin_map non-volatile.

cpumask_test_cpu() doesn't take volatile, unlike the obsoleted
cpu_isset.  The only place ia64 really cares is the spin waiting for a
bit; udelay() is probably a barrier but insert barrier() to be sure.
