Thread-topic: [PATCH][HVM] fix HVM hypercall preemption causing guest crash
Folks,

HVM guest crashes when its hypercall is preempted on x86 (pae and 32e) 
platform. For example, this happens when we install balloon driver and change 
guest memory size by 'xm mem-set'. The attached patch fixes this problem.

Regards,
Yu
