635435f4f6 Add a driver back end for the Mostek MK48T02, MK48T08 and MK48T59
time-of-day clocks, ported from NetBSD. The front-ends are expected
to be at least partly machine-dependent; the sparc64 EBus and SBus
ones will be commited to MD directories for now (in a subsequent commit).

d7f7792edf Add a generic implementation of inittodr() and resettodr(), as well as
a set of helper routines to deal with real-time clocks. The generic
functions access the clock diver using a kobj interface. This is intended
to reduce code reduplication and make it easy to support more than one
clock model on a single architecture.

This code is currently only used on sparc64, but it is planned to convert
the code of the other architectures to it later.

dd267672cd First round at trying to split up NOTES into MI and MD portions.
Unfortunately, this level doesn't really provide enough granularity.  We
probably need several MI NOTES type files for things that are shared by
several architectures but not by all.  For example, the PCI options could
live in a NOTES.pci.

This also updates the Makefile for i386 to generate LINT.  The only changes
in the generated LINT are the order of various options.

Suggestions for improvement welcome.

6c35e80948 Mutex profiling code, conditional on the MUTEX_PROFILING option. Adds the
following sysctl variables:

  debug.mutex.prof.enable	    enable / disable profiling
  debug.mutex.prof.acquisitions	    number of mutex acquisitions recorded
  debug.mutex.prof.records	    number of acquisition points recorded
  debug.mutex.prof.maxrecords	    max number of acquisition points
  debug.mutex.prof.rejected	    number of rejections (due to full table)
  debug.mutex.prof.hashsize	    hash size
  debug.mutex.prof.collisions	    number of hash collisions
  debug.mutex.prof.stats	    profiling statistics

The code records four numbers for each acquisition point (identified by
source file name and line number): longest time held, total time held,
number of non-recursive acquisitions, average time held.  The measurements
are in clock cycles (as returned by get_cyclecount(9)); this may cause
measurements on some SMP systems to be unreliable.  This can probably be
worked around by replacing get_cyclecount(9) by some incarnation of
nanotime(9).

This work was derived from initial patches by eivind.

60a57b73ef ktr changes to improve performance and make writing a userland utility to
dump the trace buffer feasible.
- Remove KTR_EXTEND.  This changes the format of the trace entries when
  activated, making writing a userland tool which is not tied to a specific
  kernel configuration difficult.
- Use get_cyclecount() for timestamps.  nanotime() is much too heavy weight
  and requires recursion protection due to ktr traces occuring as a result
  of ktr traces.  KTR_VERBOSE may still require recursion protection, which
  is now conditional on it.
- Allow KTR_CPU to be overridden by MD code.  This is so that it is possible
  to trace early in startup before pcpu and/or curthread are setup.
- Add a version number for the ktr interface.  A userland tool can check this
  to detect mismatches.
- Use an array for the parameters to make decoding in userland easier.
- Add file and line recording to the non-extended traces now that the extended
  version is no more.

These changes will break gdb macros to decode the extended version of the
trace buffer which are floating around.  Users of these macros should either
use the show ktr command in ddb, or use the userland utility which can be run
on a core dump.

d93b7c5dcd Add preliminary PC98 class to GEOM.
I have not been able to find very much information about the PC98
extended partition layout so this is gleaned from the source in
our pc98 architecture.  Corrections and patched very welcome.

d74ac6819b Compromise for critical*()/cpu_critical*() recommit. Cleanup the interrupt
disablement assumptions in kern_fork.c by adding another API call,
cpu_critical_fork_exit().  Cleanup the td_savecrit field by moving it
from MI to MD.  Temporarily move cpu_critical*() from <arch>/include/cpufunc.h
to <arch>/<arch>/critical.c (stage-2 will clean this up).

Implement interrupt deferral for i386 that allows interrupts to remain
enabled inside critical sections.  This also fixes an IPI interlock bug,
and requires uses of icu_lock to be enclosed in a true interrupt disablement.

This is the stage-1 commit.  Stage-2 will occur after stage-1 has stabilized,
and will move cpu_critical*() into its own header file(s) + other things.
This commit may break non-i386 architectures in trivial ways.  This should
be temporary.

132f08d017 Teach GEOM about Sun disklabel formats.
The detection code in this method is written so that it should work on
all architectures which means that you can plug a Sun disk into a i386
now and access the partitions.

We still need an endian-agnostic ufs/ffs before this is really
interresting, but the main focus was to get sparc64 onto the GEOM
trail.

8de00f4a87 This patch adds the "LOCKSHARED" option to namei which causes it to only acquire shared locks on leafs.
The stat() and open() calls have been changed to make use of this new functionality.  Using shared locks in
these cases is sufficient and can significantly reduce their latency if IO is pending to these vnodes.  Also,
this reduces the number of exclusive locks that are floating around in the system, which helps reduce the
number of deadlocks that occur.

A new kernel option "LOOKUP_SHARED" has been added.  It defaults to off so this patch can be turned on for
testing, and should eventually go away once it is proven to be stable.  I have personally been running this
patch for over a year now, so it is believed to be fully stable.
