OK, so looking at all of this, that statement's not quite

I agree with this. Most of it looks easily fixable, but how would I
enable the fix for ia64? For PA it's simple: I'll just use
CONFIG_STACK_GROWSUP, but that won't work for you.

Since the problem is an invalid assumption about how the stack grows,
why not just condition it on that. We actually have a config option for
this: CONFIG_STACK_GROWSUP. But for some reason ia64 doesn't define
