Subject: [PATCH v2 0/2] LKDTM powerpc enhancements - Part2
Date: Mon, 18 May 2026 12:26:03 +0530	[thread overview]
Message-ID: <cover.1778975974.git.sayalip@linux.ibm.com> (raw)

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
