x86: rename pat_wc_enabled to pat_enabled
BTW, what does pat_wc_enabled stand for? Does it mean "write-combining"? Currently it is used to globally switch on or off PAT support. Thus I renamed it to pat_enabled. I think this increases readability (and hope that I didn't miss something). Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
