From c217412e9d4df1a8b10e0cbdae5c8a24d83f1cdd Mon Sep 17 00:00:00 2001 From: Paul Durrant Date: Fri, 10 Aug 2018 16:43:42 +0100 Subject: [PATCH] x86/viridian: set shutdown_code in response to CrashNotify When Windows writes the CrashNotify bit in the CRASH_CTL MSR then we know it is crashing, so set the domain shutdown code appropriately.
