This causes kexec_add_buffer() to try to load the # kernel at the same address where initramfs will be loaded, which is # naturally rejected: # # # kexec -s -l --initrd initramfs vmlinuz # kexec_file_load failed: Invalid argument # # Setting the mem field before every call to kexec_add_buffer() fixes # this regression. # # Fixes: b6664ba42f14 ("s390, kexec_file: drop arch_kexec_mem_walk()") # Cc: stable@vger.kernel.org # v5.0+ # Signed-off-by: Thiago Jung Bauermann # Reviewed-by: Dave Young # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-gcc --version # < /opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-ld --version # < git log --format=%s --max-count=1 8b909e3548706cbebc0a676067b81aadda57f47e # < make -s -j 10 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- mmu_defconfig # make -s -j 10 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- Kernel: arch/microblaze/boot/linux.bin is ready (#1) Completed OK # rm -rf /kisskb/build/powerpc-fixes_mmu_defconfig_microblaze # Build took: 0:00:58.046471
