#     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.
#

This is often because start_here_multiplatform lacks a __init
