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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e5abb2825c66bacb76417c9a28941cdf7fd22f32 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- linkstation_defconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] Completed OK # rm -rf /kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 # Build took: 0:01:05.757129
