the sysctls. This saves a lot of space in the resulting kernel which is
important for embedded systems. This change was done in a ABI compatible
way. The pointer is still there, it just points to an empty string instead
of the description.

pmap_clear_ptes() is already convoluted. This will worsen with the
implementation of superpages. Eliminate it and add pmap_clear_write().

- Copy ethernet firmware down in small chunks so as to avoid bugs
in early versions of the bootstrap firmware.
- Attempt to "adopt" the running firmware if we cannot load a suitable
firmware image via firmware(9).
- Separate firmware validation into its own routine, and check the
major/minor driver/firmware ABI version.
instead of doing the first load with the BUS_DMA_NOWAIT flag. On 4.x with
PAE and > 4gb of RAM this proved disastrous if there weren't enough bounce
pages as amr_mapcmd() would return failure but the callback would later
fire once enough bounce pages were available and would then overwrite
another command's S/G list.

for OpenSSL to load engines run-time, e.g. for using the opensc
engine port.
The OpenSSL Configure script enables DSO support on FreeBSD by
default, we just don't use the Configure script during OpenSSL builds
in the base system.
This is committed to -CURRENT now (before OpenSSL 0.9.8b import), so
it can be tested at bit in -CURRENT before being MFC'ed to 6-STABLE.

pointer: When vm_object_deallocate() sleeps because of a non-zero
paging in progress count on either object or object's shadow,
vm_object_deallocate() must ensure that object is still the shadow's
backing object when it reawakens. In fact, object may have been
deallocated while vm_object_deallocate() slept. If so, reacquiring
the lock on object can lead to a deadlock.

to always win on my amd64. This was not my intention, so have sio be
just a tiny bit more preferred than uart.
Note: I'm not making any judgement on the merits of uart winning. I'm
just saying that if we want to change it, we do it on purpose.
pmap_remove_all() before rather than after the pmap is unlocked. At
present, the page queues lock provides sufficient sychronization. In the
future, the page queues lock may not always be held when free_pv_entry() is
called.
libmemstat(3) is used by vmstat (and friends) to produce more accurate
and more detailed statistics information in a machine-readable way,
and vmstat continues to provide the same text-based front-end.
This change should not be MFC'd.
Make three simplifications to pmap_ts_referenced():
Eliminate an initialized but otherwise unused variable.
Eliminate an unnecessary test.
Exit the loop in a shorter way.
