From 499f8f84b8324ba27d756e03f373fa16eeed9ccc Mon Sep 17 00:00:00 2001 From: Andreas Herrmann Date: Tue, 10 Jun 2008 16:06:21 +0200 Subject: 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).
