Subject: softirq/ia64: Switch to generic local_softirq_pending() implementation
X-Git-Tag: v4.19~915^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a58bdf25b98bf765b4b732f2c56097ddcb9f2d5a;p=platform%2Fkernel%2Flinux-rpi.git

softirq/ia64: Switch to generic local_softirq_pending() implementation

Benefit from the generic softirq mask implementation that rely on per-CPU
mutators instead of working with raw operators on top of this_cpu_ptr().
