kvm updates
This batch of updates is mostly Jan's rework of qemu-kvm's TPR optimization for 32-bit Windows, making Windows XP much faster with kvm enabled on older Intel and any AMD hardware. Any similarities to the original hack are purely coincidental.

Avi Kivity (1):
pc-bios: update kvmvapic.bin
Gleb Natapov (1):
kvm: Synchronize cpu state in kvm_arch_stop_on_emulation_error()
Jan Kiszka (10):
kvm: Set cpu_single_env only once
Remove useless casts from cpu iterators
Process pending work while waiting for initial kick-off in TCG mode Allow to use pause_all_vcpus from VCPU context
target-i386: Add infrastructure for reporting TPR MMIO accesses
kvmvapic: Add option ROM
kvmvapic: Introduce TPR access optimization for Windows guests
kvmvapic: Simplify mp/up_set_tpr
optionsrom: Reserve space for checksum
kvmvapic: Use optionrom helpers

What about my kvmclock kvm_enabled() fix? Should I rather submit that as part of my qom-cpu queue? It depends on it.

I am still catching up with my queue post vacation. Somehow it seems to be getting longer instead of shorter.
