From: Paolo 'Blaisorblade' Giarrusso <[email protected]>
Noticed this for a compilation-time warning, so I'm fixing it even for TT mode -
this is not put_user, but copy_to_user, so we need a pointer to sp, not sp
itself (we're trying to write the word pointed to by the "sp" var.).
Jeff, have I misunderstood anything?
