Hi Marc, Sumit
I would appreciate if you have any advice on this patch.
I haven't had a chance to look into it, as I'm not even sure I'll
take the core series in the first place (there are outstanding
regressions I can't reproduce, let alone fix them).

Subject: [PATCH 0/2] Enable support IPI_CPU_CRASH_STOP to be
pseudo-NMI
Enable support IPI_CPU_CRASH_STOP to be pseudo-NMI
This patchset enables IPI_CPU_CRASH_STOP IPI to be pseudo-NMI.
This allows kdump to collect system information even when the CPU is
in a
HARDLOCKUP state.
Only IPI_CPU_CRASH_STOP uses NMI and the other IPIs remain normal
IRQs.
The patch has been tested on ThunderX.
Which ThunderX? TX2 (at least the incarnation I used in the past) wasn't
able to correctly deal with priorities.
