    We already have something like this on ARM - include/asm-arm/memory.h

    /*
    * Allow for constants defined here to be used from assembly code
    * by prepending the UL suffix only with actual C code compilation.
    */
    #ifndef __ASSEMBLY__
    #define UL(x) (x##UL)
    #else
    #define UL(x) (x)
    #endif
