[PATCH 00/10] assorted radix fixes and improvemets for page fault and invalidation

[Nicholas Piggin <npiggin@gmail.com>]

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.

Thanks,
Nick

  KVM: PPC: Book3S HV: recursively unmap all page table entries when
    unmapping
  KVM: PPC: Book3S HV: move table entry clear unmap into helpers
  powerpc/mm/radix: implement LPID based TLB flushes to be used by KVM
  KVM: PPC: Book3S HV: radix use the Linux translation flush functions
    for partition scope
  KVM: PPC: Book3S HV: radix handle process scoped LPID flush in C, with
    relocation on
  KVM: PPC: Book3S HV: radix refine IO region partition scope attributes
  KVM: PPC: Book3S HV: radix do not clear partition pte when RC or write
