Paolo,
Here is my current queue of patches for the v4.6 merge window. They
have all been in linux-next for at least a couple of days, and in most
cases weeks.
The highlights are:
* Enable VFIO device on PowerPC, from David Gibson
* Optimizations to speed up IPIs between vcpus in HV KVM,
from Suresh Warrier (who is also Suresh E. Warrier)
* In-kernel handling of IOMMU hypercalls, and support for dynamic DMA
windows (DDW), from Alexey Kardashevskiy.
There is one merge conflict with some commits from the kvm-arm tree,
as noted by Stephen Rothwell:
"Today's linux-next merge of the kvm-ppc-paulus tree got a conflict in:
include/uapi/linux/kvm.h
between commits:
808e738142e7 ("arm64: KVM: Add a new feature bit for PMUv3")
f577f6c2a6a5 ("arm64: KVM: Introduce per-vcpu kvm device controls")
from the kvm-arm tree and commit:
01d01d69192e ("KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_64 capability number")
from the kvm-ppc-paulus tree."
Stephen fixed it up like this:
diff --cc include/uapi/linux/kvm.h
