[PATCH 1/4 V7] Add flag to indicate that a vm was stopped by the host

From: Eric B Munson
Date: Thu Dec 15 2011 - 14:43:17 EST


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.
