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. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: H.
