PS5, Line 21: #include "hwaccess.h"
Just noticed, there are some programmers that shouldn't need the old
include anymore. This gets visible when one looks at the dependencies
at the end of the chain. But we can also just test:

$ for c in $(git grep -l include\ "hwaccess_x86_io); do o=$(echo $c | sed 's/.c/.o/'); sed -i -e '/#include "hwaccess.h"/d' $c; make $o &>/dev/null && echo $c; git checkout $c &>/dev/null; done
  amd_imc.c
  atahpt.c
  atavia.c
  hwaccess_x86_io.c
  it85spi.c
  nic3com.c
  nicnatsemi.c
  nicrealtek.c
  rayer_spi.c

I've also noticed that many calls to rget_io_perms() looks spurious.
But that's for another day ;)
