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 powerpc, the following errors are reported:

arch/powerpc/mm/tlb-radix.c: In function '__tlbie_lpid':
arch/powerpc/mm/tlb-radix.c:148:2: warning: asm operand 3 probably doesn't match constraints
  asm volatile(PPC_TLBIE_5(%0, %4, %3, %2, %1)
  ^~~
arch/powerpc/mm/tlb-radix.c:148:2: error: impossible constraint in 'asm'
arch/powerpc/mm/tlb-radix.c: In function '__tlbie_pid':
arch/powerpc/mm/tlb-radix.c:118:2: warning: asm operand 3 probably doesn't match constraints
  asm volatile(PPC_TLBIE_5(%0, %4, %3, %2, %1)

arch/powerpc/mm/tlb-radix.c: In function '__tlbiel_pid':
arch/powerpc/mm/tlb-radix.c:104:2: warning: asm operand 3 probably doesn't match constraints
