The warning could be # removed, but it's potentially useful. # # All other NMIs and soft-NMIs return using EXCEPTION_RESTORE_REGS, so # this makes perf interrupts consistent with that and seems like the best # fix. # # Signed-off-by: Nicholas Piggin # [mpe: Squash in fixups from Nick] # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20221006140413.126443-3-npiggin@gmail.com # <
