KVM: MMU: fully check zero bits for sptes The #PF with PFEC.RSV = 1 is designed to speed MMIO emulation, however, it is possible that the RSV #PF is caused by real BUG by mis-configure shadow page table entries This patch enables full check for the zero bits on shadow page table entries (which includes not only bits reserved by the hardware, but also bits that will never be set in the SPTE), then dump the shadow page table hierarchy.
