locks to be able to setup a SYSINIT call. This helps in places where
a lock is needed to protect some data, but the data is not truly
associated with a subsystem that can properly initialize it's lock.
The macros use the mtx_sysinit() and sx_sysinit() functions,
respectively, as the handler argument to SYSINIT().

release times. Measurements are made and stored in nanoseconds but
presented in microseconds, which should be sufficient for the locks for
which we actually want this (those that are held long and / or often).
Also, rename some variables and structure members to unit-agnostic names.

Add a little infrastructure so that individual drivers can easily check
if thee was a vendor+product locator match.

The partition type check has been XXX'ed out since we cannot expect
that a BSD disklabel with a type field be available on all platforms.

Only if __HAVE_GENERIC_SOFT_INTERRUPTS is then splusb == splsoftnet
(because we register the interrupt with IPL_SOFTNET). However, if
we're using a callout, then splusb == splsoftclock (because the
callouts happen from the softclock interrupt).
Note that splsoftnet blocks softclock interrupts, but this is
meant to better describe what's going on.
constructs an ELF image, consisting of the ELF header, for
each memory region a program header, followed by the memory
contents for each region. It does blocked I/O for the headers
as they are typically smaller than DEV_BSIZE.

Change the operation of the USB event thread. Before it only
performed USB device discovery, now it can also perform (short)
tasks for device drivers that need a process context, but don't
have one. This is not pretty, but better than using busy-wait
in an interrupt context.
Rename memlock to sysctllock, and MEMLOCK()/MEMUNLOCK() to SYSCTL_LOCK()/
SYSCTL_UNLOCK() and related changes to make the lock names make more
sense.

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.
and cpu_critical_exit() and moves associated critical prototypes into their
own header file, <arch>/<arch>/critical.h, which is only included by the
three MI source files that need it.
Backout and re-apply improperly comitted syntactical cleanups made to files
that were still under active development. Backout improperly comitted program
structure changes that moved localized declarations to the top of two
procedures. Partially re-apply one of the program structure changes to
move 'mask' into an intermediate block rather then in three separate
sub-blocks to make the code more readable. Re-integrate bug fixes that Jake
made to the sparc64 code.
Note: In general, developers should not gratuitously move declarations out
of sub-blocks. They are where they are for reasons of structure, grouping,
readability, compiler-localizability, and to avoid developer-introduced bugs
similar to several found in recent years in the VFS and VM code.
