[Suggestion] Latest randconfig build errors for CONFIG_MMU=no

[Chen Gang]

Hello Maintainers:

  when use randconfig:
    make V=1 EXTRA_CFLAGS=-W ARCH=arm randconfig
      (and "grep CONFIG_MMU .config" outputs "# CONFIG_MMU is not set")

  the error information:
    arch/arm/kernel/suspend.c: 在函数‘cpu_suspend’中:
    arch/arm/kernel/suspend.c:56:32: 错误：提领指向不完全类型的指针
    arch/arm/kernel/suspend.c:70:3: 错误：隐式声明函数‘cpu_switch_mm’ [-Werror=implicit-function-declaration]
    arch/arm/kernel/suspend.c:71:3: 错误：隐式声明函数‘local_flush_bp_all’ [-Werror=implicit-function-declaration]
    arch/arm/kernel/suspend.c:72:3: 错误：隐式声明函数‘local_flush_tlb_all’ [-Werror=implicit-function-declaration]

  I want to be sure whether we can bear it ?

  thanks.
