[PATCH 0/3] MCE robustness fixes and LKDTM powerpc enhancements

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

Hi all,

This series fixes a panic observed while handling machine check exceptions
(MCEs) from real mode. It also improves the reliability of the
PPC_SLB_MULTIHIT test by adding isync instructions after slbmte operations,
and introduces a new LKDTM trigger (PPC_RADIX_TLBIEL) to validate MCE
behavior on radix MMU.

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

Thanks,
Sayali
