With commit a0cd7a7c4bc0 ("mm: simplify free_highmem_page() and
free_reserved_page()") the kernel test robot complains about a warning:
WARNING: modpost: vmlinux.o(.text.unlikely+0x23ac): Section mismatch in
reference from the function highmem_setup() to the function
.meminit.text:memblock_is_reserved()
This has been broken ever since microblaze added highmem support,
because memblock_is_reserved() was already tagged with "__init" back then -
most probably the function always got inlined, so we never stumbled over
it.
