KVM: x86: Add X86EMUL_F_INVLPG and pass it in em_invlpg()
Add an emulation flag X86EMUL_F_INVLPG, which is used to identify an
instruction that does TLB invalidation without true memory access.
Only invlpg & invlpga implemented in emulator belong to this kind.
invlpga doesn't need additional information for emulation. Just pass
the flag to em_invlpg().
Linear Address Masking (LAM) and Linear Address Space Separation (LASS)
don't apply to addresses that are inputs to TLB invalidation. The flag
will be consumed to support LAM/LASS virtualization.
