/* Some constant macros are used in both assembler and
* C code. Therefore we cannot annotate them always with
* 'UL' and other type specifiers unilaterally. We
* use the following macros to deal with this.
*
* Similarly, _AT() will cast an expression with a type in C, but
* leave it unchanged in asm.
