hash tables used in the sleep queue and turnstile code. Each option adds
a sysctl tree under debug containing the maximum depth of any bucket in
the hash table as well as a separate node for each bucket (or chain)
containing the current depth and maximum depth for that bucket.
vm objects shadowing source in vm_object_shadow(). This closes a race where
vm_object_collapse() could be called with a partially uninitialized object
argument causing symptoms that looked like hardware problems, e.g. signal 6,
10, 11 or a /bin/sh busy-waiting for a nonexistant child process.
the queue has been removed from the global taskqueue_queues list. This
removes the need for the draining queue hack.
- Allow taskqueue_run() to be called with the taskqueue mutex held. It
can still be called without the lock for API compatiblity. In that case
it will acquire the lock internally.
- Don't lock the individual queue mutex in taskqueue_find() until after the
strcmp as the global queues mutex is sufficient for the strcmp.
- Simplify taskqueue_thread_loop() now that it can hold the lock across
taskqueue_run().

and bump all of the taskqueue swi's to 6. This gives callouts higher
priority than taskqueue tasks and gives all taskqueue tasks the same
priority.

Add Intel Pro100Lan56 card.
Also integrate changes from Carlos Velasco. Only attch if we're a
network device (to filter out the serial devices). Also, increment
vpmatch if we match to conform to the pccard match function api.
Use bus space rather than direct inb/outb. Minor style changes while
I'm here. Extremely preliminary support for siliconix ethernet cards
(but more work is required).
The hack for setting the bus has been moved down into the cbb driver.
I've been running without this hack in my tree for so long I had
forgotten that I'd removed it :-). Please let me know if this causes
difficulty for your laptop.
starting value. This is more pedantically correct (since the handle
isn't always identical to the start of the resource) and also doesn't
access the innards of struct resource direct (which I forbid in my
tree). We need to do this for all resource types, not just ioport.
