[PATCH 0/6] QEMU ARM64 Migration Fixes

In conjunction with the kernel patch series I've just sent:

http://thread.gmane.org/gmane.comp.emulators.kvm.arm.devel/101/focus=100

These patches have been fairly heavily tested on the xgene systems
I've got access to and I'm pretty confident we've caught all the
corner cases.

From QEMU's point of view the fixes are fairly simple. We need to take
a little care when restoring the GIC that config that affects the
later restoration is restored first. The rest was simply missing
serialisation code for SPSR and FP registers.

The pl011 patch was mainly to reduce noise on re-asserting level
triggered interrupt lines. And the cpu.h documentation was for my own
sanity.

Cheers,

Alex.

target-arm: kvm: save/restore mp state
arm_gic_kvm.c: restore config before pending IRQs
hw/char/pl011: don't keep setting the IRQ if nothing changed
target-arm/kvm64.c: sync FP register state
target-arm/cpu.h: document why env->spsr exists
