+Subject: x86/microcode/AMD: Add support for fam17h microcode loading
+
+From: Tom Lendacky <thomas.lendacky@amd.com>
+
+commit f4e9b7af0cd58dd039a0fb2cd67d57cea4889abf upstream.
+
+The size for the Microcode Patch Block (MPB) for an AMD family 17h
+processor is 3200 bytes.  Add a #define for fam17h so that it does
+not default to 2048 bytes and fail a microcode load/update.
