v2 -> v3: Patch# 2: The local variable "nested_vmcb_lma" in nested_vmcb_check_cr3_cr4() has been removed. Patch# 3: Commit message has been enhanced to explain what the test is doing and why, when testing the 1-setting of the non-MBZ-reserved bits. Also, the test for legacy-PAE mode has been added. Commit header reflects this addition.
