[PATCH v2 00/11] powerpc/book3s64: Hash / SLB fixes & improvements

["Ritesh Harjani (IBM)" <ritesh.list@gmail.com>]

Hello All,

While working on slb multi-hit issue we identified few more fixes and
improvements required for Hash / SLB code. This patch series is a result of
that.

RFC -> v2:
==========
1. Addressed review comments from Christophe.
2. Added PATCH [5-8] as improvements patches.
3. Dropped the last patch which adds slb faults to vmstat counter.
   I'd like to do some more testing of this internally first, and if it proves to
   be really useful, I will send that patch separately later.

[RFC]: https://lore.kernel.org/linuxppc-dev/cover.1756522067.git.ritesh.list@gmail.com/
