From: Tom Lendacky <thomas.lendacky@xxxxxxx> This series updates the INVD intercept support for both SVM and VMX to skip the instruction rather than emulating it, since emulation of this instruction is just a NOP. For SVM, it requires creating a dedicated INVD intercept routine that invokes kvm_skip_emulated_instruction(). The current support uses the common emulate_on_interception() routine, which does not work for SEV guests, and so a Fixes: tag is added. For VMX, which already has a dedicated INVD intercept routine, it changes kvm_emulate_instruction() into a call to kvm_skip_emulated_instruction().
