+From: Kurt Garloff <garloff@suse.de>
+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.
+
