MIPS: select ARCH_KEEP_MEMBLOCK unconditionally
While removing allnoconfig_y from Kconfig, ARCH=mips allnoconfig builds
started failing with the error:
WARNING: modpost: vmlinux.o(.text+0x9c70): Section mismatch in reference
from the function reserve_exception_space() to the function
.meminit.text:memblock_reserve()
The function reserve_exception_space() references the function __meminit
memblock_reserve().
This is often because reserve_exception_space lacks a __meminit
annotation or the annotation of memblock_reserve is wrong.
ERROR: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
allnoconfig disables DEBUG_KERNEL and thus ARCH_KEEP_MEMBLOCK, which
changes __init_memblock to be equivalent to __meminit triggering the
above error.
