It would be nice to have something specific, I see nothing explicit in the current tree: arch/sparc/kernel/entry.S: * %l5 -- scratch for ld/st address arch/sparc/kernel/entry.S: * %l7 -- scratch [floppy byte, ld/st address, aux. data] arch/sparc/kernel/wuf.S:/* Now macros for the available scratch registers in this routine. */ - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
