371400cf2e Use a timeout of one second while we wait for the vnode washer,
this prevents a potential race and makes the system a little bit
less jerky under extreme loads.

34dda7fac8 Save 16 bytes per mutex if MUTEX_PROFILING is not defined.
MUTEX_PROFILING is in opt_global.h, so this does not introduce a risk of
variant structure sizes unless foreign kernel modules are used.

This saved 16 bytes per vnode and 16 bytes per vm object for a total of
4MB on a 2GB machine.

851a87ea1a Vnodes pull in 800-900 bytes these days, all things counted, so we need
to treat desiredvnodes much more like a limit than as a vague concept.

On a 2GB RAM machine where desired vnodes is 130k, we run out of
kmem_map space when we hit about 190k vnodes.

If we wake up the vnode washer in getnewvnode(), sleep until it is done,
so that it has a chance to offer us a washed vnode.  If we don't sleep
here we'll just race ahead and allocate yet a vnode which will never
get freed.

In the vnodewasher, instead of doing 10 vnodes per mountpoint per
rotation, do 10% of the vnodes distributed evenly across the
mountpoints.

402746a2d7 There is some sort of race/deadlock which I have not identified
here.  It manifests itself by sendmail hanging in "fifoow" during
boot on a diskless machine with sendmail disabled.

Giving the sleep a 1sec timout breaks the deadlock, but does not solve
the underlying problem.

XXX comment applied.

07a312f6b6 Use memset instead of __builtin_memset. Apparently there's an inline
memset in libkern which causes problems; why that's there is beyond me.

af13cb9f11 - Moved storing %g1-%g5 in the trapframe until after interrupts are enabled.
- Restore %g6 and %g7 for kernel traps if we are returning to prom code.
  This allows complex traps (ones that call into C code) to be handled from
  the prom.

a420c8119a Add 'swapctl' - as a hardlink to swapon/swapoff, and augment swapon with
swapctl functionality.  The idea is to create a swapctl command that is
fairly close to the OpenBSD and NetBSD version.  FreeBSD does not implement
swap priority (and it would be a mistake if we did) so we didn't bother with
that part of it.

5c648baca8 It is bad style to define the same structure in multiple header
files which might be included together.

Things like debuggers and lint-like programs get their knickers in
a twist (rightly so one might add) when they find different locations
for the same named struct depending on which .h file were included
first.

This is a stellar example of Very Bad Thinking on the part of the
standards dudes who wrote that both sys/uio.h and sys/socket.h
should define struct iovec the same way.

Fix this by putting struct iovec into its own miniature sys/_iovec.h
file and #include that from sys/socket.h and sys/uio.h.

Sensible people could just put iovec into sys/_types.h but there
is probably some standard or other which will be violated if we
did something that horrible.

43b7990e30 Allow the VM object flushing code to cluster. When the filesystem syncer
comes along and flushes a file which has been mmap()'d SHARED/RW, with
dirty pages, it was flushing the underlying VM object asynchronously,
resulting in thousands of 8K writes.  With this change the VM Object flushing
code will cluster dirty pages in 64K blocks.

Note that until the low memory deadlock issue is reviewed, it is not safe
to allow the pageout daemon to use this feature.  Forced pageouts still
use fs block size'd ops for the moment.

2a4689e84a Change ACPI make_dev() calls to use UID_ and GID_ constants rather
than hard-coded uids and gids.

Switch the device to a group of wheel instead of operator.

Narrow down the permissions on the device to require root privilege
to manipulate the system power state.  It may be that we can broaden
access to the device after review of the access control in ACPI.
