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

    Paolo Bonzini (3):
    KVM: x86: rename EMULATE_DO_MMIO
    KVM: x86: handle hardware breakpoints during emulation
    KVM: x86: handle singlestep during emulation
