While in principle a good idea, it # meant that the function now uses the stack. The stack is not accessible # from real mode though. # # So to keep calling the function, let's turn on MSR_DR while we call it. # That way, all pointer references to the stack are handled virtually. # # In addition, make sure to save/restore r12 on the stack, as it may get # clobbered by the C function. # # Fixes: 863771a28e27 ("powerpc/32s: Convert switch_mmu_context() to C") # Cc: stable@vger.kernel.org # v5.14+ # Reported-by: Matt Evans <matt@ozlabs.org> # Signed-off-by: Alexander Graf <graf@amazon.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20220510123717.24508-1-graf@amazon.com # < /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 ee8348496c77e3737d0a6cda307a521f2cff954f # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig # Added to kconfig CONFIG_KEXEC=y # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:3055:warning: override: reassigning to symbol KEXEC # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 # Build took: 0:00:54.533057
