-Subject: Store SRAT table revision
-References: bnc#503038
-
-In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides
-32bits for these. The new fields were reserved before.
-According to the ACPI spec, the OS must disregrard reserved fields.
-In order to know whether or not, we must know what version the SRAT
-table has.
-
-This patch stores the SRAT table revision for later consumption
-by arch specific __init functions.
-
-This is patch 1/3.
