Wouldn't it be better to move the check into kvm_release_pfn_clean()?

Hi all,
I want to implement live-migration of a highly available VM but I cannot
use shared storage.
The -b option to the migrate command already allows for copying the
block device (locally stored raw file) and that is exactly what I want.
This worked in my experiments but the VM is unreachabl

- Wrap up some confused code with a clear functio lazy_fpu_allowed()
- Update fpu while update cr4 too.

- Make fpu active explicitly while guest xsave is enab

I also notice that kvm_check_request costs lots of cpu time. Wh

This is an RFC since I have not done any comparison with the approach
using for_each_set_bit() which can be seen in Avi's work.

We did a simple test to see which requests we would get at the same time
in vcpu_enter_guest() and got the following numbers:
