From bd47a85acd727e27b7283daff557865ad04c59f6 Mon Sep 17 00:00:00 2001 From: "mike.travis@hpe.com" Date: Wed, 28 Mar 2018 12:40:11 -0500 Subject: [PATCH] x86/platform/UV: Fix critical UV MMR address error 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.
