missing global invalidations when removing copro # # With the optimizations for TLB invalidation from commit 0cef77c7798a # ("powerpc/64s/radix: flush remote CPUs out of single-threaded # mm_cpumask"), the scope of a TLBI (global vs. local) can now be # influenced by the value of the 'copros' counter of the memory context. # # When calling mm_context_remove_copro(), the 'copros' counter is # decremented first before flushing. It may have the unintended side # effect of sending local TLBIs when we explicitly need global # invalidations in this case. Thus breaking any nMMU user in a bad and # unpredictable way. # # Fix it by flushing first, before updating the 'copros' counter, so # that invalidations will be global. # # Fixes: 0cef77c7798a ("powerpc/64s/radix: flush remote CPUs out of single-threaded mm_cpumask") # Signed-off-by: Frederic Barrat <fbarrat@linux.ibm.com> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # Tested-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 cca19f0b684f4ed6aabf6ad07ae3e15e77bfd78a # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- randconfig KCONFIG_SEED=0x507AA858 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig # yes \n \| make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- In file included from /kisskb/src/arch/powerpc/xmon/xmon.c:66:0: /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_powerpc': /kisskb/src/arch/powerpc/xmon/dis-asm.h:20:2: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat] /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_spu': /kisskb/src/arch/powerpc/xmon/dis-asm.h:26:2: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat] /kisskb/src/arch/powerpc/sysdev/xive/common.c: In function 'xive_scan_interrupts': /kisskb/src/arch/powerpc/sysdev/xive/common.c:181:2: warning: 'prio' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/kvm/powerpc.c: In function 'pseries_get_cpu_char': /kisskb/src/arch/powerpc/kvm/powerpc.c:2147:17: warning: 'c.character' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/kvm/powerpc.c:2148:17: warning: 'c.behaviour' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/kernel/kexec_elf_64.c: In function 'elf64_load': /kisskb/src/arch/powerpc/kernel/kexec_elf_64.c:658:2: warning: 'fdt' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/platforms/cell/axon_msi.c: In function 'setup_msi_msg_address': /kisskb/src/arch/powerpc/platforms/cell/axon_msi.c:230:2: warning: 'prop' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/platforms/cell/axon_msi.c: In function 'find_msi_translator': /kisskb/src/arch/powerpc/platforms/cell/axon_msi.c:173:2: warning: 'ph' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/Makefile:24: CC cannot link executables.
