Yes. PPC and PPC64 have the same issues: currently this is done by
(1) putting nothing in the .init sections (on PPC64), and (2) with
stubs when jumping outside the module code.

This gives the same effect as the previous userspace loader: for PPC64
noone cares about discarding init stuff, so it's firmly on the TODO
list. ARM's priorities are obviously different.

x86_64 has this, as does sparc64: they do their own allocation. Does
ARM require something special in this regard? I'd love to see what
you've got...
