[PATCH 0/4] KVM: PPC: Convert P9 HV path to C

[Nicholas Piggin]

This applies on top of these series:

https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=238649
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=238941
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=238946

This was broken out from the large Cify series. Since that was last
posted, changes are:

- Rebase, reordering of patches, tweaking changelog and comments.
- Changed P9 radix exist SLB sanitising to use 4x slbmte to clear
  rather than 8x slbmfee/slbmfev, which turns out to be faster (and
  is what today's asm code does) [from review from Paul].
- Renamed book3s_hv_interrupt.c to book3s_hv_p9_entry.c, which reduces
  confusion with book3s_hv_interrupts.S.
- Fixed !HV compile [Alexey].
