We can ensure that the # timer always runs on one of the policy-cpus. If the timer gets # migrated to a cpu outside the policy then re-queue it back on the # policy->cpus. This way we can get rid of the smp-call which was being # used to set the pstate on the policy->cpus. # # Fixes: 7bc54b652f13 ("timers, cpufreq/powernv: Initialize the gpstate timer as pinned") # Cc: stable@vger.kernel.org # v4.8+ # Reported-by: Nicholas Piggin <npiggin@gmail.com> # Reported-by: Pridhiviraj Paidipeddi <ppaidipe@linux.vnet.ibm.com> # Signed-off-by: Shilpasri G Bhat <shilpa.bhat@linux.vnet.ibm.com> # Acked-by: Nicholas Piggin <npiggin@gmail.com> # Acked-by: Viresh Kumar <viresh.kumar@linaro.org> # Acked-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 daebe06ec4af252eba275f602a08086bc2bca5dc # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x747C6FD8 WARNING: unmet direct dependencies detected for LEDS_TRIGGER_DISK Depends on [n]: NEW_LEDS [=y] && (IDE_GD_ATA [=n] \|\| ATA [=n]) && LEDS_TRIGGERS [=y] Selected by [y]: - ADB_PMU_LED_DISK [=y] && MACINTOSH_DRIVERS [=y] && ADB_PMU_LED [=y] && LEDS_CLASS [=y] # 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-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/scripts/link-vmlinux.sh: line 85: 37467 Segmentation fault (core dumped) ${LD} ${LDFLAGS} ${LDFLAGS_vmlinux} -o ${2} -T ${lds} ${objects} /kisskb/src/Makefile:1041: recipe for target 'vmlinux' failed make[1]: * [vmlinux] Error 139 Makefile:146: recipe for target 'sub-make' failed make: * [sub-make] Error 2 Command 'make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-5.3 # Build took: 0:01:39.238175
