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.
