arch/x86/kvm/mmu.c: work around gcc-4.4.4 bug
arch/x86/kvm/mmu.c: In function 'kvm_mmu_pte_write':
arch/x86/kvm/mmu.c:4256: error: unknown field 'cr0_wp' specified in initializer
arch/x86/kvm/mmu.c:4257: error: unknown field 'cr4_pae' specified in initializer
arch/x86/kvm/mmu.c:4257: warning: excess elements in union initializer
...
gcc-4.4.4 (at least) has issues when using anonymous unions in
initializers.
