Makes the whole concept useless. This is for default printouts. If you
can build a debug kernel, you know what version you have. This was under
the concept of 'RAS' so that hapless users could tell you microversion
things. But I guess this isn't the right way according to our local
Jesuits. Oh, well. I'll think up something different and hopefully
less objectionable. And yes, NetBSD isn't linux. The developers seem
to be equally bad tempered, but linux is more successful.
Part B:
Field interrupts in OS layer so that (in this OS) bus_dmamap_sync(POSTREAD)
can (formally) ensure that the result queue is stable wrt to buffering
and that for sending a command a bus_dmamap_sync(PREWRITE) is done to
ensure that the device gets a good view of what the mailbox contents
should be.

This directory contains files which are used during PCI configuration
and PCI device drivers. Eventually, most of the device drivers and
some of the configuration support should become machine-independent
and be moved to a more general location.
The configuration support was implemented according to the `PCI Local
Bus Specification, Production Version, Revision 2.0' dated April 30,
1993. Section numbers referred to in the code may be specific to that
edition of the specification.
Some attempt has been made to insure that the code works on rogue
machines where the BIOS doesn't do its job, but in general I can't
guarantee that.
