Paolo,
Please do a pull from my kvm-ppc-next branch to get a PPC KVM update
to go into 4.12. The highlights are:
* In-kernel acceleration for IOMMU update hypercalls, from Alexey
Kardashevskiy.
* Extend the set of load/store instructions which can be used to
access emulated MMIO locations to include floating-point and
vector-scalar instructions, from Bin Lu and myself.
* Some fixes to allow PCI pass-through to work in nested guests using
PR KVM, from Alexey Kardashevskiy.
There will be a conflict in include/uapi/linux/kvm.h when you do the
merge, which can easily be fixed by assigning the next available
number for KVM_CAP_SPAPR_TCE_VFIO.
Note that some of the commits here came from Michael Ellerman's
topic/ppc-kvm branch and will also go upstream via his tree.
Thanks,
Paul.
