Re: [PATCH v8 0/6] Support for H_RPT_INVALIDATE in PowerPC KVM

This patchset adds support for the new hcall H_RPT_INVALIDATE
and replaces the nested tlb flush calls with this new hcall
if support for the same exists.

Changes in v8:
-------------
- Used tlb_single_page_flush_ceiling in the process-scoped range
  flush routine to switch to full PID invalation if
  the number of pages is above the threshold
- Moved iterating over page sizes into the actual routine that
  handles the eventual flushing thereby limiting the page size
  iteration only to range based flushing
- Converted #if 0 section into a comment section to avoid
  checkpatch from complaining.
- Used a threshold in the partition-scoped range flushing
  to switch to full LPID invalidation

[...]
