[PATCH 00/10] PAPR virtualization on PR KVM

[Alexander Graf]

In KVM for Book3S PPC we currently have 2 implementations. There
is the PR based implementation which works on any POWER system
you pass in and the super fast HV implementation which requires
libre firmware (so almost nobody can use it).

Currently, the two target two different machine types, with PR KVM
being used for bare metal system virtualization, while the HV KVM
is used to virtualize PAPR.

In an effort to make things more cozy and transparent to the user,
this patch set implements PAPR capabilities to the PR KVM side, so
a user doesn't have to worry what the respective kernel module
supports. Any machine he's virtualizing "just works".
