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-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 abc3fce76adbdfa8f87272c784b388cd20b46049 # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- FIT description: Linux 5.6.0-rc2-gabc3fce76adb Created: Sat Apr 4 01:15:42 2020 Image 0 (kernel@0) Description: Linux 5.6.0-rc2-gabc3fce76adb Created: Sat Apr 4 01:15:42 2020 Type: Kernel Image Compression: gzip compressed Data Size: 4906316 Bytes = 4791.32 KiB = 4.68 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x808ffe90 Hash algo: sha1 Hash value: 821c352d33b70b1f0a78067f4bb8b2e2d26bdab3 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Sat Apr 4 01:15:42 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Sat Apr 4 01:15:42 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Sat Apr 4 01:15:42 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 4639 Bytes = 4.53 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 018897896b42c41c943aca35a20e4300dba250c8 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Sat Apr 4 01:15:42 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 5198 Bytes = 5.08 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 36c7bd0bd79cfc2f7dd6acda6c7996294f4967e6 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Sat Apr 4 01:15:42 2020 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 # Build took: 0:01:52.495819
