kfraser@localhost.localdomain ed372f4e41 linux: More save/restore fixes. Fix deadlock of cpu_hotplug_lock vs 
workqueue_mutex. This is a new deadlock since the workqueue_mutex is
acquired in the workqueue_cpu_calbback() function across
CPU_UP_PREPARE->CPU_ONLINE.

The fix is for us not to rudely grab the cpu_hotplug_lock() during
save/restore -- it's really not necessary.

This patch is applicable to any of our 2.6 kernels, but is absolutely
required from 2.6.18 onwards.

George Dunlap 397a059280 [XEN][SHADOW] Use slow method for early-unshadow 
The "fast" method fails a significant portion of the time.
unshadow will still use the "fast" method, but will fall
back to a brute-force method if it fails.
