  "message": "x86: PAT infrastructure patch\n\nSets up pat_init() infrastructure.\n\nPAT MSR has following setting.\n\tPAT\n\t|PCD\n\t||PWT\n\t|||\n\t000 WB\t\t_PAGE_CACHE_WB\n\t001 WC\t\t_PAGE_CACHE_WC\n\t010 UC-\t\t_PAGE_CACHE_UC_MINUS\n\t011 UC\t\t_PAGE_CACHE_UC\n\nWe are effectively changing WT from boot time setting to WC.\nUC_MINUS is used to provide backward compatibility to existing /dev/mem\nusers(X).\n\nreserve_memtype and free_memtype are new interfaces for maintaining alias-free\nmapping. It is currently implemented in a simple way with a linked list and\nnot optimized. reserve and free tracks the effective memory type, as a result\nof PAT and MTRR setting rather than what is actually requested in PAT.\n\npat_init piggy backs on mtrr_init as the rules for setting both pat and mtrr\nare same.\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
