From fe5042138b6fc60edde3b60025078884c2eb71ac Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sat, 12 Mar 2011 12:50:46 +0100 Subject: [PATCH] x86: Use this_cpu_has for thermal_interrupt current cpu It is more effective to use a segment prefix instead of calculating the address of the current cpu area amd then testing flags.
