That can cause PACA_IRQ_DEC to become set when # it is not expected, and be ignored or cleared or cause warnings. # # The net result seems to be missing an irq_work until the next timer # interrupt in the worst case which is usually not going to be noticed, # however it could be a long time if the tick is disabled, which is # against the spirit of irq_work and might cause real problems. # # The idea is still solid, but it would need more work. It's not really # clear if it would be worth added complexity, so revert this for # now (not a straight revert, but replace with a comment explaining why # we might see interrupts happening, and gives git blame something to # find). # # Fixes: ebb37cf3ffd3 ("powerpc/64: irq_work avoid interrupt when called with hardware irqs enabled") # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> #
