[Qemu-devel] [PATCH v4 0/9] hmp command IO- and Local APIC dump state |

Added the hmp command to query IO- and Local APIC registers state,
it can be very useful to identify problems related to the emulation devices.

Remote IRR (none)
Changes from v1:
- implementation of hmp commands moved to the target-i386 part
- the cpu_dump_apic_local_state interface moved to the target-i386 part
Changes from v2:
- lapic and ioapic format dump are fixed for more human readable view
Changes from v3:
- added print "(none)" for empty interrupt registers
- fixed print of destination No-Shorthand
- added print IRR and Remote IRR as a bitmap in the IO APIC dump
