From 46cf98cdaef5471926010b5bddf84c44ec177fdd Mon Sep 17 00:00:00 2001 From: Venkatesh Pallipadi Date: Fri, 10 Jul 2009 09:57:37 -0700 Subject: x86, pat: Generalize the use of page flag PG_uncached Only IA64 was using PG_uncached as of now. We now intend to use this bit in x86 as well, to keep track of memory type of those addresses that have page struct for them. So, generalize the use of that bit across ia64 and x86.
