This whole chain gets inlined, # so when we free the init section (hence kvm_guest_init()), this code # goes away and hence should no longer be patched. # # We seen this as userspace memory corruption when using a memory # checker while doing partition migration testing on powervm (this # starts the code patching post migration via # /sys/kernel/mobility/migration). In theory, it could also happen when # using /sys/kernel/debug/powerpc/barrier_nospec. # # Cc: stable@vger.kernel.org # 4.13+ # Signed-off-by: Michael Neuling <mikey@neuling.org> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 51c3c62b58b357e8d35e4cc32f7b4ec907426fe3 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-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:223:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
