available.
Only directory vnodes holding no child directory vnodes held in
v_cache_src are recycled, so that directory vnodes near the root of
the filesystem hierarchy remain in namecache and directory vnodes are
not reclaimed in cascade.
The period of vnode reclaiming attempt and the number of vnodes
attempted to reclaim can be tuned via sysctl(2).

Add TI4451 as well.
These are untested since I don't have the hardware to test against.
Also, some O2Micro devices are #define w/o numbers as place holders so that
I can encourage people to submit them when they appear in the channels.
- Remove some horrible code that faked a "struct addrinfo" to be
later passed to freeaddrinfo(). Instead, add a new group type
"GT_DEFAULT" used to denote that the filesystem is exported to the
world, and treat this case separately.
- Don't clear the AI_CANONNAME flag in a struct addrinfo returned
by getaddrinfo. There's still a bit more struct addrinfo abuse
left in here.
- Simplify do_mount() slightly by using an addrinfo pointer to keep
track of the current address.
parts. This is based on the newcard code that turns it off :-). We
can now reboot after NEWCARD or Windows and have OLDCARD work. Add
support for the RL5C466 while I'm at it.
Treat TI1031 the same as the CLPD6832. It doesn't work yet, but sucks
less than it did before.
Also add a few #defines for other changes in the pipe.
- Revert del_mlist() to its pre-tirpc prototype. Unlike NetBSD's version,
ours lets the caller generate any syslog() messages, so that it
can include the service name in the message.
- Initialise a few local variables to clarify the logic and avoid some
compiler warnings.
- Remove a few unused functions and local variables, and fix some
whitespace issues.
- Reinstate the logic for avoiding duplicate host entries that got
removed accidentally in revision 1.41 (added in r1.5). This bit
was submitted in a slightly different form by Thomas Quinot.

in the TCP_COMPAT_42 case (e.g. choosing '1' as the initial sequence
number at boot-time, instead of randomizing it). TCP_COMPAT_42 is the
repository for old security holes, too :-)
and __i386__ are defined rather than if SMP and BETTER_CLOCK are defined.
The removal of BETTER_CLOCK would have broken this except that kern_clock.c
doesn't include <machine/smptests.h>, so it doesn't see the definition of
BETTER_CLOCK, and forward_*clock aren't called, even on 4.x. This seems to
fix the problem where a n-way SMP system would see 100 * n clk interrupts
and 128 * n rtc interrupts.
and AS4100s into single user mode. This work was done jointly by jhb and
myself, and builds on dfr's earlier work.
smp_init_secondary() / smp_start_secondary()
- use the uniq val to pass the globalp (me)
- fancy footwork to take any pending machine checks (me)
- doing things the FreeBSD way and getting the per-cpu idleproc created
correctly, and synchronizing the startup of secondaries (jhb)
mp_start()
- better recognition of available cpus (jhb)
smp_rendezvous()
- if smp hasn't started, only run the rendezvous function on the current
cpu. Sleuthing and (prior) incorrect fix by me, correct fix by jhb
smp_handle_ipi()
- more verbose handling of console messages (jhb)
- grab sched lock around setting PS_ASTPENDING (jhb)
forward_*clock()
- commented out. Joint decision by dfr, jhb and myself
General synchronization improvements (more mb()s, etc) (jhb)
Printf cleanups (joint)
Whitespace cleanups (jhb)
- don't do the stack overflow sanity check on MP systems -- p->p_addr
will be malloc'ed memory (not K0SEG) and the check will fail.
- don't ignore clock interrupts on secondaries. Alphas apparently
roundrobin clock interrupts to all cpus, so we're going to take clock
interrupts on all CPUS and not forward them.
- use the unique value to save the per-cpu globalp struct like the
comment says
- don't lower the ipl to ALPHA_PSL_IPL_HIGH: we may have a pending machine
check to take and we're not prepared for that yet, as we haven't setup
our interrupt entry points. (this may only happen on sable/lynx)
- indicate the fact that the working version of smp_init_secondary() doesn't
return (this is tied up in other changes and hasn't yet been committed).
