[PATCH 0/2] percpu: remove this_cpu_xor()

From: Heiko Carstens
Date: Mon Oct 21 2013 - 07:25:53 EST


While optimizing and testing s390's this_cpu ops I realized that
this_cpu_xor() generates broken code ("or" instead of "xor").

Since there is not a single user in the whole kernel tree it seems
to be a good opportunity to simply remove it instead of fixing it.

These two patches only remove the generic and x86 variant. It doesn't
touch s390 since it would only generate a merge conflict later on.
I will take care of s390 anyway if the consensus is that it should be
removed.

percpu: remove this_cpu_xor() implementation
x86: remove this_cpu_xor() implementation
