[PATCH 1/1] x86/platform/UV: Fix critical UV MMR address error

From: mike.travis
Date: Wed Mar 28 2018 - 13:46:07 EST


A critical error was found testing the fixed UV4 HUB in that an MMR
address was found to be incorrect. This causes the virtual address
space for accessing the MMIOH1 region to be allocated with the
incorrect size.
