Sean Christopherson 7b367bc9a6 KVM: x86/mmu: Return -EIO if page fault returns RET_PF_INVALID ... Exit to userspace with an error if the MMU is buggy and returns RET_PF_INVALID when servicing a page fault. This will allow a future patch to invert the emulation path, i.e. emulate only on RET_PF_EMULATE instead of emulating on anything but RET_PF_RETRY. This technically means that KVM will exit to userspace instead of emulating on RET_PF_INVALID, but practically speaking it's a nop as the MMU never returns RET_PF_INVALID.
