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> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200402120401.1115883-1-npiggin@gmail.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 abc3fce76adbdfa8f87272c784b388cd20b46049 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_ppc64_defconfig_powerpc-gcc9 # Build took: 0:03:45.543552
