Oh, I see. The <asm/atomic.h> files on tile are already reasonably well-factored. It's possible you could do better, but I think not by too much, other than possibly by using <asm-generic/atomic.h> for some of the common idioms like "subtraction is addition with a negative second argument", etc., which hasn't been done elsewhere. -- Chris Metcalf, Tilera Corp. http://www.tilera.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
