percpu: remove this_cpu_xor() implementation
There is not a single user in the whole kernel. Besides that this_cpu_xor() is broken anyway since it gets translated to this_cpu_or() (see __pcpu_size_call() line). So instead of fixing an unused definition just remove it. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Acked-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Tejun Heo <tj@kernel.org>
