From: Ingo Molnar <mingo@xxxxxxx>

fix an GFP_KERNEL allocation in atomic section: kvm_dev_ioctl_create_vcpu() called kvm_mmu_init(), which calls alloc_pages(), while holding the vcpu.

The fix is to set up the MMU state in two phases: kvm_mmu_create() and kvm_mmu_setup().

(NOTE: free_vcpus does an kvm_mmu_destroy() call so there's no need
for any extra teardown branch on allocation/init failure here.)

Applied, thanks.
