Compared to the last version, I've:
(1) dropped the vmalloc patches
(2) updated the kmem cache for the guest_fpu field in the kvm_vcpu_arch
     struct to be sized according to fpu_kernel_xstate_size
(3) Added minimum FPU checks in KVM's x86 init logic to avoid memory
     corruption issues.

Whatever happened to this series?

There was a question about the usage of kmem_cache_create_usercopy, and a v7
was never sent.

What's that go to do with anything? :-D
