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

Both changes look good to me.
You should send them to Kees, who maintains lkdtm. I've added him to Cc, but that may not be sufficient to get his attention.
