Subject: clocksource: em_sti: Set cpu_possible_mask to fix SMP broadcast
From: Magnus Damm <damm@xxxxxxxxxxxxx>
commit 2199a5574b6d94b9ca26c6345356f45ec60fef8b upstream.
Update the STI driver by setting cpu_possible_mask to make EMEV2
SMP work as expected together with the ARM broadcast timer.
This breakage was introduced by:
f7db706 ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real hardware clock-event
Without this fix SMP operation is broken on EMEV2 since no
broadcast timer interrupts trigger on the secondary CPU cores.
