x86: PAT Update validate_pat_support for intel CPUs Pentium III and Core Solo/Duo CPUs have an erratum " Page with PAT set to WC while associated MTRR is UC may consolidate to UC " which can result in WC setting in PAT to be ineffective. We will disable PAT on such CPUs, so that we can continue to use MTRR WC setting. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
