cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

463931b3ba Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

2aba26f773 - auxio cleanup and sbus support.
- make GENERIC64 include GENERIC and set the 3 optoins it needs.  suggested
  by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
  the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed

4044b5a41c Use separate callouts for motor-on and motor-off. Fixes a condition
where the floppy driver would wedge because a motor-on timeout would
be cancelled by another I/O operation cancelling a motor-off timeout.

7b918b4088 New callout mechanism with two major improvements over the old
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.

3b51289caa Revamp interrupts again:
Fix a bug causing interrmittent panics in interrupt dispatch.
	Use interrupt vectors for softints.
	Add a new send_softint interface.
	Improved D$ flushing.
	Improve traptrace and other debugging enhancements.

fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.

1884f05354 Another general cleanup:
Remove the entire idea of fasttrap interrupts since V9 traps are really cheap,
the CPUs are really fast, and the completely different trap frames would make
these handlers really difficult to implement.

pmap_changeprot() was only used by the clock and one other place; deprecate it.

probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we
can probe IO locations by physical addresses.

Some pmap cleanup.

Some more copyright cleanup.

186c3eba2b Make pbrobeget() and probeset() work for 64-bit values as well. To do this
the arguments are changed so the address is first and the ASI second so we
can have the address in %o0:%o1 and not worry about unused registers.

Also a bit of copyright cleanup.

f6f9f8a965 Change DIOCEJECT to do what's needed to eject a device before the eject
command (unlock for sd and cd) if no other partitions are open, return
EBUSY otherwise. DIOCEJECT will have the old semantic if its argument is not
0. The old ioctl has been renamed to ODIOCEJECT for binary compatibility.
