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 v5:
-------------
- Included the h_rpt_invalidate page size information within
mmu_pszie_defs[] as per David Gibson's suggestion.
- Redid nested exit changes as per Paul Mackerras' suggestion.
- Folded the patch that added tlbie primitives into the
hcall implementation patch.
v4: https://lore.kernel.org/linuxppc-dev/20210215063542.3642366-1-bharata@linux.ibm.com/T/#t
