12 * Stolen from linux/const.h, which can't be directly included since
13 * this is used in userspace code, which has no access to the kernel
14 * headers. Changed to be suitable for adding casts to the start,
15 * rather than "UL" to the end.
18 /* Some constant macros are used in both assembler and
19 * C code. Therefore we cannot annotate them always with
20 * 'UL' and other type specifiers unilaterally. We
21 * use the following macros to deal with this.
