sparc/mm: remove register_page_bootmem_info()
Patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)".
We want to remove CONFIG_HAVE_BOOTMEM_INFO_NODE. As a first step, let's
limit the remaining harm to x86 and core code, removing sparc, ppc and
s390 leftovers, starting the stepwise removal by removing and simplifying
some code.
Once a related x86 vmemmap fix [1] is in, we can merge part 2 that will
remove CONFIG_HAVE_BOOTMEM_INFO_NODE entirely.
Tested on x86-64 with hugetlb vmemmap optimization in combination with
KMEMLEAK, making sure that the problem reported in dd0ff4d12dd2 ("bootmem:
remove the vmemmap pages from kmemleak in put_page_bootmem") does not
reappear -- hoping I managed to trigger the original problem.
This patch (of 8):
sparc does not select CONFIG_HAVE_BOOTMEM_INFO_NODE, therefore,
register_page_bootmem_info_node() is a nop.
Let's just get rid of register_page_bootmem_info().
