powerpc/kexec: Fix loading of kernel + initramfs with kexec_file_load()
Commit b6664ba42f14 ("s390, kexec_file: drop arch_kexec_mem_walk()") changed kexec_add_buffer() to skip searching for a memory location if kexec_buf.mem is already set, and use the address that is there. In powerpc code we reuse a kexec_buf variable for loading both the kernel and the initramfs by resetting some of the fields between those uses, but not mem. 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.
