961135ead8 - Remove <machine/mutex.h>. Most of the headers were empty, and the
contents of the ones that were not empty were stale and unused.
- Now that <machine/mutex.h> no longer exists, there is no need to allow it
  to override various helper macros in <sys/mutex.h>.
- Rename various helper macros for low-level operations on mutexes to live
  in the _mtx_* or __mtx_* namespaces.  While here, change the names to more
  closely match the real API functions they are backing.
- Drop support for including <sys/mutex.h> in assembly source files.

of dereferencing NULL pointers. This eases implementation of platforms

483cc44070 Follow the lead of vendor's interrupt moderation mechanism.
It seems RTL8169/RTL8168/RTL810xE has a kind of interrupt
moderation mechanism but it is not documented at all. The magic
value dramatically reduced number of interrupts without noticeable
performance drops so apply it to all RTL8169/RTL8169 controllers.
Vendor's FreeBSD driver also applies it to RTL810xE controllers but
their Linux driver explicitly cleared the register, so do not
enable interrupt moderation for RTL810xE controllers.

While I'm here sort 8169 specific registers.

0867cb9511 o) Recognize the Lanner MR-730.
o) Fix enumeration of PHY addresses on the MR-955.
o) Parse link state for the MR-730 using the Broadcom PHY support in the SDK.
   It's not clear that this is entirely-correct, but it seems to work.  Since
   this board uses a BCM5482S, this may mean that we work correctly for copper
   but not SFI, which is untested.

c5b0b5fc6b Sync the APIC startup sequence with amd64:
- Register APIC enumerators at SI_SUB_TUNABLES - 1 instead of SI_SUB_CPU - 1.
- Probe CPUs at SI_SUB_TUNABLES - 1.  This allows i386 to set a truly
  accurate mp_maxid value rather than always setting it to MAXCPU - 1.

2bc085c69c Reduce spin wait time consumed in GMII register access routine.
There were a couple of attempts in the past to reduce it since it
took more than 1ms. Because mii_tick() periodically polls link
status, waiting more than 1ms for each GMII register access was
overkill. Unfortunately all previous attempts were failed with
various ways on different controllers.
This time, add additional 20us dealy at the end of GMII register
access which seems to requirement of all RealTek controllers to
issue next GMII register access request. This is the same way what
Linux does.

Andrew Thompson
cefd33c787 Hook up the five gpio pins on the Avila board to the gpio framework. There are
actually 16 I/O lines but the other ones are used for system devices and
interrupts.

The IXP4XX platform can set interrupts on these pins for
high/low/rising/falling/transitional but this is not implemented yet.

The Cambria has the same interface but as all the pins are assigned to system
functions the gpio header is toggled via a PLD on the i2c bus and is not
supported by this commit.
