名称描述
__show_regs
read_cr3_paFriendlier CR3 helpers.
__get_current_cr3_fastThis can be used from process context to figure out what the value of* CR3 is without needing to do a (slow) __read_cr3().* It's intended to be used for code like KVM that sneakily changes CR3* and needs to restore it. It needs to be used very carefully.
