Rename ruxagg()->ruxagg_locked(), ruxagg_tlock()->ruxagg() [1].
The ruxagg_locked() function no longer clears thread ticks nor
td_incruntime.

X-MFC-Note: td_rux shall be moved to the end of struct thread
on Cassini using the external PCS SERDES otherwise unaligned access
traps and other strange effects happen with some machines. Don't touch
the MIF which is unused in that case either. These changes require the
PHY type to use to be determined via the OFW device tree or from the
VPD in machines without the former.
- Disable the SERDES pins of Saturn when not used in order to save power
and ensure they are enabled otherwise.
- In cas_attach() use the correct register offset for CAS_PCS_CONF_EN.
- Add some bus space barriers missing in the PCS code path.
These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as
the on-board interfaces found in Sun Fire B100s Blade Server work.

CTF can not represent enums with more than CTF_MAX_VLEN members, but
ctfconvert will happily ignore that limitation and create CTF section no
other tool can interpret.
This change is different from similar change from upstream, which just
returns an error if big enum is encountered. Doing that means that
every FreeBSD kernel with compiled in hwpmc will have no useable CTF
information due to pmc_event enum having 1236+ members.

the allocated pages. Moreover, they are mapped with pmap_qenter(), which
creates unmanaged mappings.

quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only

to unconditionally set PG_REFERENCED on a page before sleeping. In many
cases, it's perfectly ok for the page to disappear, i.e., be reclaimed by
the page daemon, before the caller to vm_page_sleep() is reawakened.
Instead, we now explicitly set PG_REFERENCED in those cases where having
the page persist until the caller is awakened is clearly desirable. Note,
however, that setting PG_REFERENCED on the page is still only a hint,
and not a guarantee that the page should persist.
