From 8a7b12f70fb135a1b1d865687de3edcdc780f6d1 Mon Sep 17 00:00:00 2001 From: "venkatesh.pallipadi@intel.com" Date: Thu, 18 Dec 2008 11:41:31 -0800 Subject: x86: PAT: change pgprot_noncached to uc_minus instead of strong uc - v3 Impact: mm behavior change. Make pgprot_noncached uc_minus instead of strong UC. This will make pgprot_noncached to be in line with ioremap_nocache() and all the other APIs that map page uc_minus on uc request.
