On second thought, I also think we should avoid solutions where the
BE/LE test has to be done for each and every I/O accessor call again
and again.  We should rather do this just once, and for example set
function pointers as needed (hoping that this driver will only be
needed after relocation, so we have writable data segment).

Best regards,

Wolfgang Denk

Mike's Law: For a lumber company employing two men and a cut-off saw,
the marginal product of labor for any number  of  additional  workers
equals  zero  until the acquisition of another cut-off saw. Let's not
even consider a chainsaw.
