7f5a9c7a36 Retire PMAP_DIAGNOSTIC. Any useful diagnostics that were conditionally
compiled under PMAP_DIAGNOSTIC are now KASSERT()s.  (Note: The kernel
option DIAGNOSTIC still disables inlining of certain pmap functions.)

Eliminate dead code from pmap_enter().  This code implemented an assertion.
On i386, an equivalent check is already implemented.  However, on amd64,
a small change is required to implement an equivalent check.

Eliminate \n from a nearby panic string.

Use KASSERT() to reimplement pmap_copy()'s two assertions.

b9ae01c4c7 Add a macro STRICT_ASSIGN() to help avoid the compiler bug that
assignments and casts don't clip extra precision, if any.  The
implementation is to assign to a temporary volatile variable and read
the result back to assign to the original lvalue.

lib/msun currently 2 different hard-coded hacks to avoid the problem
in just a few places and needs it in a few more places.  One variant
uses volatile for the original lvalue.  This works but is slower than
necessary.  Another temporarily casts the lvalue to volatile.  This
broke with gcc-4.2.1 or earlier (gcc now stores to the lvalue but
doesn't load from it).

c553ad248f Add an alternative view of the bits in an 80-bit long double (64+16
instead of 32+32+15+1) on all arches that have such long doubles (amd64,
ia64 and i386).  Large objects should be be accessed in large units,
and the 32+32+15+1[+padding] decomposition asks for almost the opposite
of that, sometimes resulting in very slow accesses depending on how
well the compiler ignores what we ask for and converts to the best
units for the given machine.  E.g., on Athlons, there is a 10-20 cycle
penalty for accessing the middle 32-bit word immediately after an
80-bit store.

Whether actually using the alternative view is better is very machine-
dependent.  A 32+32+16 view is probably best with old 32-bit systems
and gcc through 4.2.1.  The compiler should mostly avoid the view and
generate best accesses, but gcc-4.2.1 is far from doing that.  I think
64+16 is best for now.  Similarly for doubles -- they should be using
64+0 especially on 64-bit machines, but fdlibm uses 32+32 extensively
for them.  Fortunately, in 64-bit mode for doubles, gcc already ignores
the 32+32-bit view and generates best accesses in many cases.

691f99e98f Translate from the i386. All FP constants and operations are evaluated
in the range and precision of their type(s) on amd64, but FLT_EVAL_METHOD
said that they were evalated in the "interesting" (buggy) i387 methods.
float_t was broken compatibly with FLT_EVAL_METHOD.

These definitions seem to be broken on powerpc and possibly on arm.
float_t is float on powerpc with gcc [-notraditional] according to
glibc, and FLT_EVAL_METHOD is marked with XXX on arm.

0957a8f3c9 Add optional support to mxge for MSI-X interrupts and multiple receive
queues (which we call slices).  The NIC will steer traffic into up to
hw.mxge.max_slices different receive rings based on a configurable
hash type (hw.mxge.rss_hash_type).

Currently the driver defaults to using a single slice, so the default
behavior is unchanged.  Also, transmit from non-zero slices is
disabled currently.

291172a6df Update to firmware version 1.4.29 from 1.4.25. Relevant changes include:
- Fix a bug introduced in 1.4.20 where speculative read by the processor in the
   write-only doorbell region would cause a target-abort (as opposed to simply
   returning random data). This could manifest itself as NMI or machine freeze
   depending on how the BIOS/OS/chipset configuration handles target-abort.

- Add support for new revisions of -R cards (with AEL1002/AEL1010 xaui->xfi)

- Increase an internal timing (dispatch engine): fix possible spurious reset
  (seen on very few cards).

7a1cea460a - When executing the 'tryself' branch in sched_pickcpu() look at the
lowest priority on the queue for the current cpu vs curthread's
   priority.  In the case that curthread is waking up many threads of a
   lower priority as would happen with a turnstile_broadcast() or wakeup()
   of many threads this prevents them from all ending up on the current cpu.
 - In sched_add() make the relationship between a scheduled ithread and
   the current cpu advisory rather than strict.  Only give the ithread
   affinity for the current cpu if it's actually being scheduled from
   a hardware interrupt.  This prevents it from migrating when it simply
   blocks on a lock.

58dd567f36 Overhaul re(4).
o Increased number of Rx/Tx descriptors to 256 for 8169 GigEs
  because it's hard to push the hardware to the limit with default
  64 descriptors.
  TSO requires large number of Tx descriptors to pass a full sized
  TCP segment(65535 bytes IP packet) to hardware. Previously it
  consumed 32 Tx descriptors, assuming MCLBYTES DMA segment size,
  to send the TCP segment which means re(4) couldn't queue more
  than two full sized IP packets.
  For 8139C+ it still uses 64 Rx/Tx descriptors due to its hardware
  limitations. With this changes there are (very) small waste of
  memory for 8139C+ users but I don't think it would affect 8139C+
  users for most cases.
o Various bus_dma(9) fixes.
   - The hardware supports DAC so allow 64bit DMA operations.
   - Removed BUS_DMA_ALLOC_NOW flag.
   - Increased DMA segment size to 4096 from MCLBYTES because TSO
     consumes too many descriptors with MCLBYTES DMA segment size.
   - Tx/Rx side bus_dmamap_load_mbuf_sg(9) support. With these
     changes the code is more readable than previous one and got a
     (slightly) better performance as it doesn't need to pass/
     decode arguments to/from callback function.
   - Removed unnecessary callback function re_dmamap_desc() and
     nuked rl_dmaload_arg structure which was used in the callback.
   - Additional protection for DMA map load failure. In case of
     failure reuse current map instead of returning a bogus DMA
     map.
  -  Deferred DMA map unloading/sync operation for maximum
     performance until we really need to load new DMA map. If we
     happen to reuse current map(e.g. input error) there is no need
     to sync/unload/load again.
  -  The number of allowable Tx DMA segments for a mbuf chains are
     now 32 instead of magic nseg value. If the number of available
     Tx descriptors are short enough to send highly fragmented mbuf
     chains an optimized re_defrag() is called to collapse mbuf
     chains which is supposed to be much faster than m_defrag(9).
     re_defrag() was borrowed from ath(4).
   - Separated Rx/Tx DMA tag from a common DMA tag such that Rx DMA
     tag correctly uses DMA maps that were created with DMA alignment
     restriction(8bytes alignments). Tx DMA tag does not have such
     alignment limitation.
   - Added additional sanity checks for DMA ring map load failure.
   - Added additional spare Rx DMA map for graceful handling of Rx
     DMA map load failure.
   - Fixed misused bus_dmamap_sync(9) and added missing
     bus_dmamap_sync(9) in re_encap()/re_txeof()/re_rxeof().
o Enabled TSO again as re(4) have reasonable number of Tx
  descriptors.
o Don't touch DMA address of a Tx descriptor in re_txeof(). It's
  not needed.
o Fix incorrect update of if_ierrors counter. For Rx buffer
  shortage it should update if_qdrops as the buffer is reused.
o Added checks for unsupported H/W revisions and return ENXIO for
  these hardwares. This is required to remove resource allocation
  code in re_probe as other drivers do in device probe routine.
o Modified descriptor index manipulation macros as it's now possible
  to have different number of descriptors for Rx/Tx.
o In re_start, to save a lock operation, use IFQ_DRV_IS_EMPTY before
  trying to invoke IFQ_DRV_DEQUEUE. Also don't blindly call re_encap
  since we already know the number of available Tx descriptors in
  advance.
o Removed RL_TX_DESC_THLD which was used to reserve RL_TX_DESC_THLD
  descriptors in Tx path. There is no such a limitation mentioned in
  8139C+/8169/8110/8168/8101/8111 datasheet and it seems to work ok
  without reserving RL_TX_DESC_THLD descriptors.
o Fix a comment for RL_GTXSTART. The register is 8bits register.
o Added comments for 8169/8139C+ hardware restrictions on descriptors.
o Removed forward declaration for "struct rl_softc", it's not needed.
o Added a new structure rl_txdesc for Tx descriptor managements and
  a structure rl_rxdesc for Rx descriptor managements.
o Removed unused member variable rl_intlock in driver softc. There are
  still several unused member variables which are supposed to be used
  to access hardware statistics counters. But it seems that accessing
  hardware counters were not implemented yet.
