Here's various patches for radix, a few small bugfixes, tracepoint
enablement or partition scope tlbie, and some page fault optimisation.
This was tested with the patch to qemu that enables THP for partition
scope page tables and things seem to work as expected.
Changes since v2:
- Rebased on to powerpc topic/ppc-kvm branch which contains "[PATCH v2
5/9] powerpc/mm/radix: implement LPID based TLB flushes to be used
by KVM" from this series, and also a change to the kvm pmd allocator
- Updated some changelogs and comments a little bit.
- Re-tested with QEMU that does proper 2MB alignment, verified we're
still seeing events for partition scope TLB and PWC flushing.
