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.

Sashiko has provided some comments (https://sashiko.dev/#/patchset/cover.1778057685.git.sayalip%40linux.ibm.com), so I am planning to split this into two patch series. I will send v2 part 1 today with the proposed change for "powerpc/time: Remove preempt_disable/enable from arch_irq_work_raise()", and v2 part 2 with the remaining two patches later.
Thanks for the review, Ritesh and Shrikanth. Regards, Sayali
