I have to correct myself. Even for disk io you will see allocations smaller
than 1k/4k. I've noticed that while debugging the dvma code for my Sun 3/80.
I guess the only assumption, which is still true for kernel only use is the
aligned. But I can think of a bad program, which uses scsi generic devices
and doesn't align scsi commands and data.
This device has completely bogus header. Compaq scores again :-|
It's a host bridge, but it should be called ghost bridge instead ;^)
