    ARM: omap: allow building omap44xx without SMP · c7a9b09b
    Arnd Bergmann authored
    The new omap4 cpuidle implementation currently requires
    ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.
    This patch makes it possible to build a non-SMP kernel
    for that platform. This is not normally desired for
    end-users but can be useful for testing.
    Without this patch, building rand-0y2jSKT results in:
    drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke':
    drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]
    It's not clear if this patch is the best solution for
    the problem at hand. I have made sure that we can now
    build the kernel in all configurations, but that does
    not mean it will actually work on an OMAP44xx.
