From eae3ee7d8a7c59cf63441dedf28674889f5fc477 Mon Sep 17 00:00:00 2001 From: Eric B Munson Date: Sat, 10 Mar 2012 14:37:25 -0500 Subject: [PATCH] x86: pvclock: Add flag to indicate that a vm was stopped by the host This flag will be used to check if the vm was stopped by the host when a soft lockup was detected. The host will set the flag when it stops the guest. On resume, the guest will check this flag if a soft lockup is detected and skip issuing the warning.
