[PATCH v2 0/3] KVM: arm64: single step emulation instructions

[Alex Bennée]

Hi,

This is rev 2 of the series. The main change is I've moved the helper
into it's own patch and changed it's return to a bool rather than try
and straddle the different return semantics of kvm_handle_mmio_return
and handle_exit.

The result is we no longer have code motion in patch 2 (now 3) to
introduce the helper making it embarrassingly short - but hopefully a
lot clearer.

As usual revision details bellow the --- in each patch.

Alex Bennée (3):
  kvm: arm debug: introduce helper for single-step
  kvm: arm64: handle single-stepping trapped instructions
  kvm: arm64: handle single-step of userspace mmio instructions
