Add C99-style constructor macros for fixed types to <asm-generic/int-*.h>. Since Linux uses names like "u64" instead of "uint64_t", the constructor macros are called U64_C() instead of UINT64_C() and so forth. These macros allow specific sizes to be specified as U64_C(0x123456789abcdef), without gcc issuing warnings as it will if one writes (u64)0x123456789abcdef. When used from assembly, these macros pass their argument unchanged. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
