It seems the same is true on arc, arm64, powerpc, s390, sparc, tile and x86,
and we'd ideally move all others the same way.
Almost all uses of the bootmem interfaces are in architectures specific code
these days, the only exceptions I could find at all are alloc_bootmem_pages
in drivers/xen/swiotlb-xen.c, and alloc_bootmem in drivers/macintosh/smu.c
and init/main.c.
I don't know how the effort to remove bootmem is progressing, but I guess
we could avoid adding new users if we move the existing implementation into
the architectures that still use it, remove the interfaces not used by
those architectures and rename the other ones to have a prefix identifying
the architecture.
