The patch titled
powerpc: allow smp_call_function_single() to current cpu
has been removed from the -mm tree. Its filename was
powerpc-allow-smp_call_function_single-to-current-cpu.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: powerpc: allow smp_call_function_single() to current cpu
From: Avi Kivity <avi@xxxxxxxxxxxx>
This removes the requirement for callers to get_cpu() to check in simple
cases. i386 and x86_64 already received a similar treatment.
