tree:
- td_standin is (k + a) as it is only touched by either curthread or when
a thread is being created.
- td_upcall is (k + j)
- td_sticks is (k) rather than the earlier (j) note.
- td_uuticks and td_usticks are both (k).
- td_intrval is (j)
- Neither kg_nextupcall or kg_upquantum seem to be locked and that seems
to be on purpose, so mark those as (n).

It can be used to delay mounting root partition to give a chance to GEOM
providers to show up.
Now, when there is no needed provider, vfs_rootmount() function will look
for it every second and if it can't be find in defined time, it'll ask
for root device name (before this change it was done immediately).
This will allow to boot from gmirror device in degraded mode.
Users should move to the new geom_vinum implementation instead.
The refcount logic which is being added to devices to enable safe module
unloading and the buf/vm work also in progress would require a major rework
of the (old)-vinum code to comply with the new semantics.
The actual source files will not be removed until I have coordinated with
the geomvinum people if they need any bits repo-copied etc.
of the number of threads which are inside whatever is behind the
cdevsw for this particular cdev.
Make the device mutex visible through dev_lock() and dev_unlock().
We may want finer granularity later.
Replace spechash_mtx use with dev_lock()/dev_unlock().
and disklabel.5. Refrencing bsdlabel.5 is somewhat bogus as it is not
connected to the build and is mostly unwritten at this point.

in atomic(9), but is API (and ABI) compatible and simply makes sense.
This feature will primarily be used for atomic PTE updates in PMAP/ng.
specified mutex is invalid. In spec parlance 'MAY FAIL' means it's
up to the implementor. So, remove the check for NULL pointers for two
reasons:
1. A mutex may be invalid without necessarily being NULL.
2. If the pointer to the mutex is NULL core-dumping in the
vicinity of the problem is much much much better than failing
in some other part of the code (especially when the application
doesn't check the return value of the function that you oh so
helpfully set to EINVAL).
