It works nicely.

But IMHO this whole infrastructure should go for now, at least until gcc
is able to produce functions with this call convention on its own. Or it
needs to be restricted to only assembler functions. The other users of
this may only work because the stack protector is already disabled for
arch/x86/xen/mmu.o.
