I do the sign extension with tiny stubs in arch/sparc64/kernel/sys32.S so that the arg frobbing does not consume a stack frame, which is what happens if you do this in C code.
We need to revisit this at some point and make a way for all compat platforms to do this with a portable table of some kind that expands a bunch of macros defined by the platform. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
