include/linux/kernel.h: make might_fault() a nop for !MMU
The machine cannot fault if !MUU, so make might_fault() a nop for !MMU.
This fixes below build error if
!CONFIG_MMU && (CONFIG_PROVE_LOCKING=y || CONFIG_DEBUG_ATOMIC_SLEEP=y):
arch/arm/kernel/built-in.o: In function `arch_ptrace':
arch/arm/kernel/ptrace.c:852: undefined reference to `might_fault'
arch/arm/kernel/built-in.o: In function `restore_sigframe':
arch/arm/kernel/signal.c:173: undefined reference to `might_fault'
...
arch/arm/kernel/built-in.o:arch/arm/kernel/signal.c:177: more undefined references to `might_fault' follow
make: *** [vmlinux] Error 1
