[PATCH 0/2] KVM: x86: minimal debugging support during emulation

The switch to emulate_invalid_guest_state brought one slightly unwelcome
change; the debugging interface does not work in the initial boot phase
because KVM_SET_GUEST_DEBUG is basically ignored.

These two patches bring some initial support for debugging, namely for
hardware breakpoints and single-stepping. Software breakpoints and
hardware watchpoints are still ignored.

v1->v2: rename EMULATE_DO_MMIO to EMULATE_USER_EXIT;
return EMULATE_* value via pointer-to-int argument.
