This is because emergency_ctx is still # addressed with its virtual address allthough data MMU is not active # anymore at that time. # # Fix it by using a physical address instead. # # Fixes: c118c7303ad5 ("powerpc/32: Fix vmap stack - Do not activate MMU before reading task struct") # Cc: stable@vger.kernel.org # v5.10+ # Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/ce30364fb7ccda489272af4a1612b6aa147e1d23.1637227521.git.christophe.leroy@csgroup.eu # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 5bb60ea611db1e04814426ed4bd1c95d1487678e # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] <stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version ...
