This is new version of ondemand nested state allocation.=0D
=0D
In this version I dropped the changes to set_efer and instead=0D
added a new request KVM_REQ_OUT_OF_MEMORY which makes the kvm=0D
exit to userspace with KVM_EXIT_INTERNAL_ERROR=0D
=0D
This request is used in (unlikely) case of memory allocation=0D
failure.=0D
=0D
