Thread-topic: [patch]Fix a bug about reboot failure after S3

Hi, Keir,

 

“warm reset vector” is used to start APs. At booting time, it is set by BP, and cleared after all APs have started. When do S3, similar work need to do. However, when enable non-boot CPUs after S3, Xen just sets this vector, but forgets to clear it after APs startup. This patch fix the issue.
