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 error is reported:

arch/mips/kernel/cpu-bugs64.c: In function 'mult_sh_align_mod.constprop':
arch/mips/kernel/cpu-bugs64.c:33:2: error: asm operand 1 probably doesn't match constraints [-Werror]
