It used # to work (by chance ?) because CPU wake-up interrupt never comes from # user, so r2 is expected to point to 'current' on return. # # Commit e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access # Protection") broke it even more by clobbering r0 which is not # restored by fast_exception_return either. # # Use r6 instead of r0. This is possible because r3-r6 are restored by # fast_exception_return and only r3-r5 are used for exception arguments. # # For r2 it could be converted back to virtual address, but stay on the # safe side and restore it from the stack instead. It should be live # in the cache at that moment, so loading from the stack should make # no difference compared to converting it from phys to virt. # # Fixes: f7354ccac844 ("powerpc/32: Remove CURRENT_THREAD_INFO and rename TI_CPU") # Fixes: e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access Protection") # Cc: stable@vger.kernel.org # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/6d02c3ae6ad77af34392e98117e44c2bf6d13ba1.1580121710.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9933819099c4600b41a042f27a074470a43cf6b9 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:208:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
