ppc/xive queue:
* Various bug fixes around lost interrupts particularly.
* Major group interrupt work, in particular around redistributing
interrupts. Upstream group support is not in a complete or usable
state as it is.
* Significant context push/pull improvements, particularly pool and
phys context handling was quite incomplete beyond trivial OPAL
case that pushes at boot.
* Improved tracing and checking for unimp and guest error situations.
* Various other missing feature support.
Is there anything in there which should be picked up for
stable qemu branches?
Thanks,
