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/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 f01ad0b9f2dcfd006e1fa77104fdf989980ff20f # < make -s -j 8 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig arch/m68k/configs/multi_defconfig:322:warning: symbol value 'm' invalid for MCTP # < make -s -j 8 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 8 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 8 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- <stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] Completed OK # rm -rf /kisskb/build/powerpc-fixes_m68k-defconfig_m68k-gcc11 # Build took: 0:04:11.456268
