NFSv2 cannot cope with a big number of vnodes, so revert to NPROC-based
calculation until the problem is fixed, okay beck@ art@

Dynamic buffer cache. Initial diff from mickey@, okay art@ beck@ toby@
deraadt@ dlg@.

better desiredvnodes not based on maxusers; pedro@ deraadt@ ok

recycle swbuf that had been long gone (w/ old vm)
(this is in preparation for approaching GBC work)

Crank SHMMNI from 32 -> 128 and SHMSEG from 8 -> 128. OK deraadt@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

nbuf doesn't belong here. It's declared on all architectures instead.
And here it goes into the bss, while it's initialized in MD code.

Add variables for config(8) -e time tweak of systemV shared memory
parameters.

Ok millert@, miod@, maja@

Patch from Daniel Lucq <daniel@lucq.org>

The patch allows you to change the value of NMBCLUSTERS, BUFCACHEPERCENT
and NKMEMPAGES using the config command, instead of recompiling the kernel.

This is the kernel part of the patch. I have compiled it on i386, sparc64,
alpha and macppc. -moj ok art@ maja@

nswbuf hasn't been used for ages. gc.

Remove even more old timeout tentacles.

seminfo.semmap and SEMMAP are not used; kill them
Solaris doesn't have these either...

Get rid of REAL_CLISTS. It was never implemented and the tentacles are
everywhhere.

Remove old vm.

convert mbuf and cluster allocation to pool, mostly from NetBSD
okay art@ miod@

Get rid of CLSIZE and all related stuff.
CLSIZE -> 1
CLBYTES -> PAGE_SIZE
OLOFSET -> PAGE_MASK
etc.
At the same time some archs needed some cleaning in vmparam.h so that
goes in at the same time.

no vm_cache_max in uvm; ok art@

New API for timeouts. Replaces the old timeout()/untimeout() API and
makes it the callers responsibility to allocate resources for the
timeouts.

This is a KISS implementation and does _not_ solve the problems of slow
handling of a large number of pending timeouts (this will be solved in
future work) (although hardclock is now guarateed to take constant time
for handling of timeouts).

Old timeout() and untimeout() are implemented as wrappers around the new
API and kept for compatibility. They will be removed as soon as all
subsystems are converted to use the new API.

double ncallout, until art fixes this further

Update comment to reflect reality.

Undo changes which were not discussed.

defopt TIMEZONE

Increase NVNODE.

move vm_cache_max into param.c
make it maxusers adaptive
note, that NTEXT approximation is probably not the best idea
