No problem (and in fact I wouldn't mind you merging all of
x86_64/asm_defns.h into the other file - that due at some point
anyway), but I'm afraid we'd want this to be yet another separate
prerequisite patch - not sure if you're up to that, or if you wouldn't
find it simpler to keep SAVE_ALL being a C macro then.
