[PATCH v2 0/2] LKDTM powerpc enhancements - Part2

[Sayali Patil <sayalip@linux.ibm.com>]

Hi all,

This series adds a new LKDTM trigger PPC_RADIX_TLBIEL, to validate
machine check handling on radix MMU systems and improves reliability of
the PPC_SLB_MULTIHIT test by adding isync instructions after slbmte
operations.

Please review the patches and provide any feedback or suggestions
for improvement.

Thanks,
Sayali
