If you could split this out into a separate changeset, it would help.  You don't
have to, but it would help make the review process go quicker since there would
be fewer things for me to keep track of.

Done.

     "ebp_exception_handler_wrapper:\n"
     "mov %ebp, saved_ebp\n"
     "jmp ebp_exception_handler\n"
