v1 -> v2:
	In patch# 1, the parameter to nested_vmcb_check_controls() has been
	changed to 'struct kvm_vcpu' from 'struct vcpu_svm'. This necessiated
	relevant changes to its callers.
	Also, the new checks in nested_vmcb_check_controls() now use
	page_address_valid() instead of duplicating code.

	It has also been rebased to v5.11-rc3.
