Sean Christopherson 8d214c4816 KVM: x86: Reset MMU context if guest toggles CR4.SMAP or CR4.PKE
Reset the MMU context during kvm_set_cr4() if SMAP or PKE is toggled.
Recent commits to (correctly) not reload PDPTRs when SMAP/PKE are
toggled inadvertantly skipped the MMU context reset due to the mask
of bits that triggers PDPTR loads also being used to trigger MMU context
resets.
