[PATCH v2 0/2] INVD intercept change to skip instruction

[Tom Lendacky]

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().

Tom Lendacky (2):
  KVM: SVM: Add a dedicated INVD intercept routine
  KVM: VMX: Do not perform emulation for INVD intercept
