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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-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_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc5200_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S: Assembler messages: /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S:184: Warning: invalid register expression INFO: Uncompressed kernel (size 0x825900) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x825900) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x825900) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x815248) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Image Name: Linux-5.10.0-rc2-g8077155dce6c Created: Sat Nov 21 01:57:57 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3766611 Bytes = 3678.33 KiB = 3.59 MiB Load Address: 00900000 Entry Point: 00900284 Image Name: Linux-5.10.0-rc2-g8077155dce6c Created: Sat Nov 21 01:57:57 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3737438 Bytes = 3649.84 KiB = 3.56 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.10.0-rc2-g8077155dce6c Created: Sat Nov 21 01:57:57 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3766416 Bytes = 3678.14 KiB = 3.59 MiB Load Address: 00900000 Entry Point: 00900284 Image Name: Linux-5.10.0-rc2-g8077155dce6c Created: Sat Nov 21 01:57:57 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3766579 Bytes = 3678.30 KiB = 3.59 MiB Load Address: 00900000 Entry Point: 00900284 Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc5200_defconfig_powerpc-gcc5 # Build took: 0:00:46.610644
