Series | arm/arm64: Allow the rescheduling IPI to bypass irq_enter/exit | expand |
Hi Marc, I plan to add NMI patches which enables IPI_CPU_CRASH_STOP IPI as pseudo-NMI[1]. But I know need to resolve the instrumentation issues before that. I think need to moving arm64 entry code over to the generic entry code(kernel/entry/common.c) for that, is this right? Can you tell me current status? Let me know if there's anything I can do to help. [1]https://lore.kernel.org/lkml/20201104080539.3205889-1-ito-yuichi@fujitsu.com/ Thanks, Yuichi Ito

Mark is working on this, I believe. I'll let him comment on the current state of things. Thanks, M.
