So xxx_p is for pause (or something like that).
This also matches that m68k do some tricks with delay() in the _p variants.
Thanks for the explanation.

m68k's isa_delay() uses the same approach as x86's slow_down_io(),
but only for Q40/Q60, which has a "real" ISA bus that accepts legacy
ISA expansion cards (http://www.q40.de/).

Based on the nice description from James I have on my todo list
to cook up a patch to io.h to document this.
Had just not got around to do it yet.
