From 84292b29475bc7bb6b04ae5360595bd816ca4efb Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 21 Oct 2013 13:25:36 +0200 Subject: 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.
