From 105da50df4fe6073575a2eb6247d916746b6143e Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Sat, 5 Jan 2013 12:17:46 +0800 Subject: AMD: Set the mask of MTRR according to CONFIG_CPU_ADDR_BITS The high bits of mtrr mask are MBZ (Must be zero). Writing 1 to these bits will cause exception. So be carefull when spread this change. The supermicro/h8scm needs more work. Currently it is set as it was. We need to check if the F10 and F15 have different value.
