b13e838a49 Implement RUSAGE_THREAD. Add td_rux to keep extended runtime and ticks
information for thread to allow calcru1() (re)use.

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

62ac140238 - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDES
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.

ba89ec5469 Do not encode more than CTF_MAX_VLEN(1023) enum members.
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.

0ec9744723 It makes more sense for the object-based backend allocator to use OBJT_PHYS
objects instead of OBJT_DEFAULT objects because we never reclaim or pageout
the allocated pages.  Moreover, they are mapped with pmap_qenter(), which
creates unmanaged mappings.

queue length. The default value for this parameter is 50, which is
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
sysctl with the same name, so that it's possible to retrieve the
current value.

630328c1b5 Add support for SPARC64 V (and where it already makes sense for other
HAL/Fujitsu) CPUs. For the most part this consists of fleshing out the
MMU and cache handling, it doesn't add pmap optimizations possible with
these CPU, yet, though.
With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250
and likely also other models based on SPARC64 V like 450, 650 and 850.
Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.

f35e97166b It makes no sense for vm_page_sleep_if_busy()'s helper, vm_page_sleep(),
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.

1b4eb78965 This change addresses the race condition that was introduced by the previous
revision, r207450, to this file.  Specifically, between dropping the page
queues lock in vm_contig_launder() and reacquiring it in
vm_contig_launder_page(), the page may be removed from the active or
inactive queue.  It could be wired, freed, cached, etc.  None of which
vm_contig_launder_page() is prepared for.
