[RFC/PATCH 00/15] kvm on big iron
This patch series introduces a backend for kvm to run on IBM System z
machines that uses the mainframe's sie virtualization capability. This
work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with
a 64bit linux host. Userspace will follow once we're done brushing it
over.
The patch queue consists of the following patches, which can be applied
in sequence on top of kvm.git
