"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
such as the LM78 and VT82C686A (and eventually ACPI). Multiple
sensor devices can be hooked registered with `sysmon', and eventually
sysmon will also handle hardware (and software) watchdog timers.
Convert the `lm' and `viaenv' drivers to the new interface.
have _detach() functions:
Ensure that softc keeps state about whether the attach succeeded,
and make the detach function return immediately if the attach did
not complete.
This work is based on code written by Scott D. Telford, the IBM
Token Ring card attachment was written by Gregory McGarry.

is not a reasonable place to allocate 12-bit pcmcia iospace.
It seems to cause conflicts on a large number of modern laptops,
necesitating hand-patching of the kernel (mostly due to
video devices in the upper range of that space).
This will presumably cause problems on the NEC Versa 6030X,
however that appears to be a vastly less common case than
the laptops that are inconvenienced by the current state.
12-bit iospace now uses 0x400-0xfff.
but the registers actually begin at 0x3f2, and this is what PNPBIOS reports
for the floppy controller resources. Adjust the register offsets and the
mapping of them for the ISA front-end to compensate, so that the PNPBIOS
attachment of the floppy controller actually works.
where the floppy driver would wedge because a motor-on timeout would
be cancelled by another I/O operation cancelling a motor-off timeout.

timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
a call to hook up a bell-ringer (since the keyboard itself has no bell).
This eliminates the need for #ifdefs for the bell-ringer in the pckbd
driver.
- Add cnbell() support to pckbd.
