* This is used by architectures to keep arguments on the stack
* untouched by the compiler by keeping them live until the end.
* The argument stack may be owned by the assembly-language
* caller, not the callee, and gcc doesn't always understand
* that.
*
* We have the return value, and a maximum of six arguments.
*
* This should always be followed by a "return ret" for the
* protection to work (ie no more work that the compiler might
* end up needing stack temporaries for).
