commit 57977c4bf379c7f0b3dcf8b9a97a76214bfdf677
Author: Will Newton <will.newton@linaro.org>

    ARM: Fix compiler warnings from atomic.h
    
    __arch_compare_and_exchange_bool_*_int return a boolean so in the
    dummy implementations for 8, 16 and 64 bits return zero rather than
    oldval. Zero is used rather than TRUE or FALSE to avoid needing to
    including any headers for these dummy functions.
