[Qemu-devel] [PATCH v3 0/9] hmp command IO- and Local APIC dump state

["Denis V. Lunev" <den@openvz.org>]

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.

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
