[PATCH v3 0/2] powerpc/mce: Fix mce handler and add selftest

This patch series fixes mce handling for pseries, Adds LKDTM test
for SLB multihit recovery and enables selftest for the same,
basically to test MCE handling on pseries/powernv machines running
in hash mmu mode.

v3:
* Merging selftest changes with patch 2/2, Instead of having separate
  patch.
* Minor improvements like adding enough comments, Makefile changes,
  including header file and adding some prints.

v2:
* Remove in_nmi check before calling nmi_enter/exit,
  as nesting is supported.
* Fix build errors and remove unused variables.
* Integrate error injection code into LKDTM.
* Add support to inject multihit in paca.
