I thought about that, but the last argument to
of_kexec_alloc_and_setup_fdt() is extra_fdt_size and the allocation
done is for this:
fdt_size = fdt_totalsize(initial_boot_params) +
(cmdline ? strlen(cmdline) : 0) +
FDT_EXTRA_SPACE +
extra_fdt_size;
and kexec_fdt_totalsize_ppc64() also includes
fdt_totalsize(initial_boot_params) so I was not sure. Maybe
kexec_fdt_totalsize_ppc64() needs modification as well?
