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 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:25:0, from /kisskb/src/sound/ppc/awacs.c:29: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:220:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
