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/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 8077155dce6c20909682788466ddb25af743cb73 # < make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- defconfig arch/ia64/configs/generic_defconfig:58:warning: override: reassigning to symbol ATA arch/ia64/configs/generic_defconfig:59:warning: override: reassigning to symbol ATA_PIIX # < make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- help # make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- olddefconfig # make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-fixes_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/ia64/include/uapi/asm/intrinsics.h:22:0, from /kisskb/src/arch/ia64/include/asm/intrinsics.h:11, from /kisskb/src/arch/ia64/include/asm/timex.h:14, from /kisskb/src/include/linux/timex.h:65, from /kisskb/src/include/linux/time32.h:13, from /kisskb/src/include/linux/time.h:73, from /kisskb/src/fs/nfs/read.c:11: /kisskb/src/fs/nfs/read.c: In function 'nfs_read_completion': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:196:5: note: in expansion of macro 'xchg' xchg(&nfs_req_openctx(req)->error, error); ^ /kisskb/src/fs/nfs/read.c: In function 'nfs_readpage': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr))) __xchg((unsigned long) (x), (ptr), sizeof((ptr)))) ^ /kisskb/src/fs/nfs/read.c:355:2: note: in expansion of macro 'xchg' xchg(&ctx->error, 0); ^ No errors detected in 22326 functions.
