From 55a6ca25472ee01574bfc24d23b7f5fa09cc38cf Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 23 Nov 2009 15:12:07 -0800 Subject: x86, mm: Call is_untracked_pat_range() rather than is_ISA_range() Checkin fd12a0d69aee6d90fa9b9890db24368a897f8423 made the PAT untracked range a platform configurable, but missed on occurrence of is_ISA_range() which still refers to PAT-untracked memory, and therefore should be using the configurable.
