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 # <
