They don't have alot of reason to be in sbin and contribute to library

locks held by each thread.
- Fix a bug in the original BSD/OS code where a contested lock was not
properly handed off from the old thread to the new thread when a
contested lock with more than one blocked thread was transferred from
one thread to another.
- Don't use an atomic operation to write the MTX_CONTESTED value to
mtx_lock in the aforementioned special case. The memory barriers and
exclusion provided by sched_lock are sufficient.

disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
see if the device is disabled in the identify routine instead of in the
probe routine. This way if the device is disabled it is never created.
Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled". If this is a big problem, resource_disabled() can always be
changed to honor both names.
careful to call all map_load calls with BUS_DMA_NOWAIT because we
really don't want some PDUs to wait while others go out - ATM guarantees
the ordering of cells and also of PDUs (within one VC, that is). With
BUS_DMA_NOWAIT bus_dmamap_load should never return EINPROGRESS.
Make the tag used for transmission buffers one larger than the maximum
AAL5 PDU (65535). This is needed, because all PDU sizes need to be round
up to multiple of four for the card and PDUs that are just below the
maximum size will be rounded up to 65536
All .s files that need cpp(1) processing (see gcc(1) manpage's
DESCRIPTION section) have been repo-copied to .S files. This
is mostly to bring bsd.lib.mk in agreement with sys.mk.

real SATA disks now that I can test it.
Add support for the SiI 3112 SATA chip using memory mapped I/O.
Update the support for the SiI 0680 to use the memio interface as well.

null-terminating (which is doesn't actually happen due to stack alignment
padding).

Create a private, single underscore, version of pthread_mutex_unlock for libc.
pthread_mutex_lock already has one. These versions are different from the
ones that applications will link against because they block all signals
from the time a call to lock the mutex is made until it is successfully
unlocked.

it was a matter of coincidence.

o use a mutex to protect the bounce pages structure.
o use a SYSINIT function to initialize the bounce pages structures
and thus avoid a race condition in alloc_bounce_pages().
o add support for the BUS_DMA_NOWAIT flag in bus_dmamap_load().
o remove obsolete splhigh()/splx() calls.
o remove printf() about incorrect locking in busdma_swi() and sync
busdma_swi() with the one of the alpha backend.
o use __FBSDID.
system by specifying the file system ID instead of a path. Use this
by default in umount(8). This avoids the need to perform any vnode
operations to look up the mount point, so it makes it possible to
unmount a file system whose root vnode cannot be looked up (e.g.
due to a dead NFS server, or a file system that has become detached
from the hierarchy because an underlying file system was unmounted).
It also provides an unambiguous way to specify which file system is
to be unmunted.
Since the ability to unmount using a path name is retained only for
compatibility, that case now just uses a simple string comparison
of the supplied path against f_mntonname of each mounted file system.

a thread receives a spurious wakeup from sigtimedwait(), so make sure
that the call to the queueing code is called only once before entering
the loop (not in the loop). This should fix some fatal errors people
are seeing with messages stating the thread is already on the mutex queue.
These errors may still be triggered from signal handlers; however, since
that part of the code is not locked down yet.
