This patch can't be applied
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:

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

Enable KVM FPU fully eager restore, if there is other FPU state which isn't
tracked by CR0.TS bit.
v4 changes from v3:
- Wrap up some confused code with a clear functio lazy_fpu_allowed()
- Update fpu while update cr4 too.
v3 changes from v2:
- Make fpu active explicitly while guest xsave is enab
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

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