This commit increases the size of struct kvm_mmu_page by 64 bytes on
x86_64 (184 bytes -> 248 bytes). The size of this struct can be reduced
in future commits by moving TDP MMU root fields into a separate struct
and by dynamically allocating fields only used by the Shadow MMU.

I think it's already possible to use a union like

	union {
		struct kvm_mmu_page_arch arch;
		struct {
			struct work_struct work;
			void *data;
		};
	};
