Paolo, Radim,
This is the bulk of the KVM/arm changes for 4.20. This time, the
biggest change by far is the support for variable addressing range in
guests, allowing userspace to size arm64 VMs from 32 to 52bits instead
of the hard-coded 40bits we've enjoyed so far. Other than that, we
have a random selection of small fixes and cleanups.
Note that this will generate a few minor conflicts with the arm64 tree,
which should be resolved as per this branch[1].
Please pull,
M.
