This breaks for offline # CPUs because they don't get the IPI to flush their TLB. This can lead # to stale translations. # # Fix this by clearing the CPU from mm_cpumasks, then flushing all TLBs # before going offline. # # These offlined CPU bits stuck in the cpumask also prevents the cpumask # from being trimmed back to local mode, which means continual broadcast # IPIs or TLBIEs are needed for TLB flushing. This patch prevents that # situation too. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20201120025757.325930-3-npiggin@gmail.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 8077155dce6c20909682788466ddb25af743cb73 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc8560_ads_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8560ads.dtb.dts.tmp: No such file or directory compilation terminated. make[2]: * [scripts/Makefile.lib:326: arch/powerpc/boot/dts/fsl/mpc8560ads.dtb] Error 1 make[2]: * Waiting for unfinished jobs.... make[1]: * [arch/powerpc/Makefile:294: zImage] Error 2 make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 # Build took: 0:00:27.046005
