This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.

If it is enabled for mips, the following errors are reported:

arch/mips/mm/sc-mips.o: In function `mips_sc_prefetch_enable.part.2':
sc-mips.c:(.text+0x98): undefined reference to `mips_gcr_base'
sc-mips.c:(.text+0x9c): undefined reference to `mips_gcr_base'
sc-mips.c:(.text+0xbc): undefined reference to `mips_gcr_base'
sc-mips.c:(.text+0xc8): undefined reference to `mips_gcr_base'
sc-mips.c:(.text+0xdc): undefined reference to `mips_gcr_base'
arch/mips/mm/sc-mips.o:sc-mips.c:(.text.unlikely+0x44): more undefined references to `mips_gcr_base'

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Changes in v3:
  - forcibly inline __ffs() too

Changes in v2:
  - new patch
