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.

6c3c2b8b87 Remove stub symbols for APIC-related functions when 'device apic' is not
included in a kernel config.  These stubs had existed previously so that
acpi.ko could always include the MADT parsing code and still link with a
kernel that did not include 'device apic'.

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.

a7c6aabdc3 Instead of using the AMRR ratectl algo as default for drivers which have
the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if
a driver calls ieee80211_ratectl_init() check if the NONE algo is still
selected and try to use AMRR in that case. Drivers are still free to use
any other algo by calling ieee80211_ratectl_set() prior to the
ieee80211_ratectl_init() call.

After this change it is now safe to assume that a ratectl algo is always
available and selected, which renders the IEEE80211_C_RATECTL flag pretty
much useless. Therefore revert r211314 and 211546.

9fe3e6c023 Fix a use-after-free bug for extended IRQ resource[1]. When _PRS buffer is
copied as a template for _SRS, a string pointer for descriptor name is also
copied and it becomes stale as soon as it gets de-allocated[2].  Now _CRS is
used as a template for _SRS as ACPI specification suggests if it is usable.
The template from _PRS is still utilized but only when _CRS is not available
or broken.  To avoid use-after-free the problem in this case, however, only
mandatory fields are copied, optional data is removed, and structure length
is adjusted accordingly.

0534aae0ce Add simple MAC statistics counter reading support. Unfortunately
useful counters like rl_missed_pkts is 16 bits quantity which is
too small to hold meaningful information happened in a second. This
means driver should frequently read these counters in order not to
lose accuracy and that approach is too inefficient in driver's
view. Moreover it seems there is no way to trigger an interrupt to
detect counter near-full or wraparound event as well as lacking
clearing the MAC counters. Another limitation of reading the
counters from RealTek controllers is lack of interrupt firing at
the end of DMA cycle of MAC counter read request such that driver
have to poll the end of the DMA which is a time consuming process
as well as inefficient. The more severe issue of the MAC counter
read request is it takes too long to complete the DMA. All these
limitation made maintaining MAC counters in driver impractical. For
now, just provide simple sysctl interface to trigger reading the
MAC counters. These counters could be used to track down driver
issues. Users can read MAC counters maintained in controller with
the following command.
#sysctl dev.re.0.stats=1

While I'm here add check for validity of dma map and allocated
memory before unloading/freeing them.
