[PATCH 1/2] Fix merge problem between sparc32 IPI patches and schedule_ipi() callback

From: Daniel Hellstrom
Date: Fri May 20 2011 - 10:02:50 EST


Fixes a merge conflict in arch/sparc/kernel/smp_32.c between commit
d6d048192b1d ("sparc32: implement SMP IPIs using the generic functions")
from the sparc tree and commit 184748cc50b2 ("sched: Provide
scheduler_ipi() callback in response to smp_send_reschedule()").

The patch adds a call to scheduler_ipi() from the resched IPI handler in
sparc32.
