our kernel module system learned how to handle dependencies.
Providing a whole bunch of shell scripts that do nothing but load
a similarly named kernel loadable module is out of vogue.
The svr4(8) manual page has been replaced with a much better svr4(4)
page.
timeout. If DIAGNOSTIC is turned on, then display a message to the console
with a map of which CPUs failed to stop or restart. This gives an SMP box
at least a fighting chance of getting into DDB if one of the other CPUs has
interrupts disabled.
Fix amr_map_command so that 40LD-specific commands get the scatter-gather
list count in the right place. I don't understand why AMI did it like
this, but now the AMI MegaManager can talk to the newer (1600 and later)
controllers.
Remove an unused variable.
Include <machine/clock.h> when necessary.
Tweak some debugging levels to make things more intelligible.
Alter consumers of this method to conform to the new convention.
Minor cosmetic adjustments to bus.h.
This isn't of concern as this interface isn't in use yet.
io or memory space access enabled. This patch defers the setting
of these bits until after all of the mapping registers are probed.
It might be even better to defer this until a particular mapping
is activated and to disable that type of access when a new
register is activated.
2) The PCI spec is very explicit about how mapping registers and
the expansion ROM mapping register should be probed. This patch
makes cardbus_add_map() follow the spec.
3) The PCI spec allows a device to use the same address decoder for
expansion ROM access as is used for memory mapped register access.
This patch carefully enables and disables ROM access along with
resource (de)activiation.
This doesn't include the prefetching detection stuff (maybe later when code is written to actually turn on prefetching). It also does not use the PCI definitions (yet, I'll try to put this in all at once later)

- Make pccbb/cardbus kld loadable and unloadable.
- Make pccbb/cardbus use the power interface from pccard instead of inventing its own.
- some other minor fixes
The release engineer keeps using the wrong /boot/cdboot when creating the
ISO images. So we'll add the 4.0-RELEASE cdboot to the tree until someone
bothers to fix the source so a working `cdboot' is built.
1) mpsafe (protect the refcount with a mutex).
2) reduce duplicated code by removing the inlined crdup() from crcopy()
and make crcopy() call crdup().
3) use M_ZERO flag when allocating initial structs instead of calling bzero
after allocation.
4) expand the size of the refcount from a u_short to an u_int, by using
shorts we might have an overflow.

use a mutex lock when looking up/deleting entries on the hashlist
use a mutex lock on each uidinfo when updating fields
make uifree() a void function rather than 'int' since no one cares
allocate uidinfo structs with the M_ZERO flag and don't explicitly initialize
them

This makes a pretty dramatic difference to the amount of work that
the harvester needs to do - it is much friendlier on the system.
(80386 and 80486 class machines will notice little, as the new
get_cyclecounter() call is a wrapper round nanotime(9) for them).
the interface to use callout_* instead of timeout(). Also add an
IS_MPSAFE #define (currently off) which will mark the driver as mpsafe
to the upper layers.
before adding/removing packets from the queue. Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.
IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue. An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.
Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.
