3.13.11-ckt32 -stable review patch.  If anyone has any objections, please let 
me know.


From: James Hogan <james.ho...@imgtec.com>

commit 585bb8f9a5e592f2ce7abbe5ed3112d5438d2754 upstream.

If either of the memory allocations in kvm_arch_vcpu_create() fail, the
vcpu which has been allocated and kvm_vcpu_init'd doesn't get uninit'd
in the error handling path. Add a call to kvm_vcpu_uninit() to fix this.
