Looks like the call was added fairly recently by:

    arm64: To remove initrd reserved area entry from memblock

which claims it is to work around the initrd being displayed in
/sys/kernel/debug/memblock/reserved.

I really think we need to have common behavior there - either do this
for all architectures or none.  I've just sent a series that
consolidates all but a handful of the free_initrd_mem, so implementing
any common behavior on top of that would be good.
