f6f1dfb66b Re-introduce a global ath_hal_debug again for now, whilst I figure out what
to do about the few cases where the HAL state isn't available (regdomain)
or isn't yet setup (probe/attach.)

The global ath_hal_debug now affects all instances of the HAL.

This also restores the ability for probe/attach debugging to work; as
the sysctl tree may not be attached at that point. Users can just set
the global "hw.ath.hal.debug" to a suitable value to enable probe/attach
related debugging.

37931a3544 Break out most of the HAL related tweaks into a per-HAL instance,
rather than global variables.

This specifically allows for debugging to be enabled per-NIC, rather
than globally.

Since the ath driver doesn't know about AH_DEBUG, and to keep the ABI
consistent regardless of whether AH_DEBUG is enabled or not, enable the
debug parameter always but only conditionally compile in the debug
methods if needed.

The ALQ support is currently still global pending some brainstorming.

a49399a903 Set negative quality to TSC timecounter when C3 state is enabled for Intel
processors unless the invariant TSC bit of CPUID is set.  Intel processors
may stop incrementing TSC when DPSLP# pin is asserted, according to Intel
processor manuals, i. e., TSC timecounter is useless if the processor can
enter deep sleep state (C3/C4).  This problem was accidentally uncovered by
r222869, which increased timecounter quality of P-state invariant TSC, e.g.,
for Core2 Duo T5870 (Family 6, Model f) and Atom N270 (Family 6, Model 1c).

38d7a61ba4 Add a helper routine to conditionally modify the start address of a
resource allocation from an x86 Host-PCI bridge driver so that it can be
reused by the ACPI Host-PCI bridge driver (and eventually the MPTable
Host-PCI bridge driver) instead of duplicating the same logic.  Note that
this means that hw.acpi.host_mem_start is now replaced with the
hw.pci.host_mem_start tunable that was already used in the non-ACPI case.
This also removes hw.acpi.host_mem_start on ia64 where it was not
applicable (the implementation was very x86-specific).

While here, adjust the logic to apply the new start address on any
"wildcard" allocation even if that allocation comes from a subset of
the allowable address range.

register both status change and link state change callbacks.
Implement checking valid link in state change callback and poll
active link state in vr_tick().  This allows immediate detection of
lost link as well as protecting driver from frequent link flips during
link renegotiation.  taskq implementation was removed because driver
now needs to poll link state in vr_tick().

0b96c05a7a After we get a good power signal, always wait about 10ms before
proceeding.

On boot, some laptops with certain cards in them sometimes fail on
boot, but if the card is inserted after boot it works.  Experiments
show that small delays here makes things more reliable.  It is
believed that some combinations need a little more time before the
power on the card is really stable enough to be reliable once the
power is stable in the bridge.

183c8af32e Don't create a device_t object or parse current resources (via _CRS) for
ACPI Device() objects that do not have any device IDs available via the
_HID or _CID methods.  Without a device ID a device driver cannot attach
to the device anyway.  Namespace objects that are devices but not of
type ACPI_TYPE_DEVICE are not affected.

A few BIOSes have also attached a _CRS method to a PCI device to
allocate resources that are not managed via a BAR.  With the previous
code those resources are allocated from acpi0 directly which can interfere
with the new PCI-PCI bridge driver (since the PCI device in question may
be behind a bridge and its resources should be allocated from that
bridge's windows instead).  The resources were also orphaned and
and would end up associated with some other random device whose device_t
reused the pointer of the original ACPI-enumerated device (after it was
free'd by the ACPI PCI bus driver) in devinfo output which was confusing.
If we want to handle _CRS on PCI devices we can adjust the ACPI PCI bus
driver to do that in the future and associate the resources with the
proper device object respecting PCI-PCI bridges, etc.

Note that with this change the ACPI PCI bus driver no longer has to
delete ACPI-enumerated device_t devices that mirror PCI devices since
they should in general not exist.  There are rare cases when a BIOS
will give a PCI device a _HID (e.g. I've seen a PCI-ISA bridge given
a _HID for a system resource device).  In that case we leave both the
ACPI and PCI-enumerated device_t objects around just as in the previous
code.

1c2ed38455 - Use a dedicated task to handle deferred transmits from the if_transmit
method instead of reusing the existing per-queue interrupt task.
  Reusing the per-queue interrupt task could result in both an interrupt
  thread and the taskqueue thread trying to handle received packets on a
  single queue resulting in out-of-order packet processing.
- Don't define igb_start() at all on 8.0 and where if_transmit is used.
  Replace last remaining call to igb_start() with a loop to kick off
  transmit on each queue instead.
- Call ether_ifdetach() earlier in igb_detach().
- Drain tasks and free taskqueues during igb_detach().

8a8a3387fd Several enhancements to the Xen block back driver.
sys/dev/xen/blkback/blkback.c:
	o Implement front-end request coalescing.  This greatly improves the
	  performance of front-end clients that are unaware of the dynamic
	  request-size/number of requests negotiation available in the
	  FreeBSD backend driver.  This required a large restructuring
	  in how this driver records in-flight transactions and how those
	  transactions are mapped into kernel KVA.  For example, the driver
	  now includes a mini "KVA manager" that allocates ranges of
	  contiguous KVA to patches of requests that are physically
	  contiguous in the backing store so that a single bio or UIO
	  segment can be used to represent the I/O.

	o Refuse to open any backend files or devices if the system
	  has yet to mount root.  This avoids a panic.

	o Properly handle "onlined" devices.  An "onlined" backend
	  device stays attached to its backing store across front-end
	  disconnections.  This feature is intended to reduce latency
	  when a front-end does a hand-off to another driver (e.g.
	  PV aware bootloader to OS kernel) or during a VM reboot.

	o Harden the driver against a pathological/buggy front-end
	  by carefully vetting front-end XenStore data such as the
	  front-end state.

	o Add sysctls that report the negotiated number of
	  segments per-request and the number of requests that
	  can be concurrently in flight.

283d6f7287 Monitor and emit events for XenStore changes to XenBus trees
of the devices we manage.  These changes can be due to writes
we make ourselves or due to changes made by the control domain.
The goal of these changes is to insure that all state transitions
can be detected regardless of their source and to allow common
device policies (e.g. "onlined" backend devices) to be centralized
in the XenBus bus code.

sys/xen/xenbus/xenbusvar.h:
sys/xen/xenbus/xenbus.c:
sys/xen/xenbus/xenbus_if.m:
	Add a new method for XenBus drivers "localend_changed".
	This method is invoked whenever a write is detected to
	a device's XenBus tree.  The default implementation of
	this method is a no-op.

sys/xen/xenbus/xenbus_if.m:
sys/dev/xen/netfront/netfront.c:
sys/dev/xen/blkfront/blkfront.c:
sys/dev/xen/blkback/blkback.c:
	Change the signature of the "otherend_changed" method.
	This notification cannot fail, so it should return void.

sys/xen/xenbus/xenbusb_back.c:
	Add "online" device handling to the XenBus Back Bus
	support code.  An online backend device remains active
	after a front-end detaches as a reconnect is expected
	to occur in the near future.

sys/xen/interface/io/xenbus.h:
	Add comment block further explaining the meaning and
	driver responsibilities associated with the XenBus
	Closed state.

sys/xen/xenbus/xenbusb.c:
sys/xen/xenbus/xenbusb.h:
sys/xen/xenbus/xenbusb_back.c:
sys/xen/xenbus/xenbusb_front.c:
sys/xen/xenbus/xenbusb_if.m:
	o Register a XenStore watch against the local XenBus tree
	  for all devices.
	o Cache the string length of the path to our local tree.
	o Allow the xenbus front and back drivers to hook/filter both
	  local and otherend watch processing.
	o Update the device ivar version of "state" when we detect
	  a XenStore update of that node.

sys/dev/xen/control/control.c:

sys/xen/xenbus/xenbusb.c:
sys/xen/xenbus/xenbusb.h:

	Allow clients of the XenStore watch mechanism to attach
	a single uintptr_t worth of client data to the watch.
	This removes the need to carefully place client watch
	data within enclosing objects so that a cast or offsetof
	calculation can be used to convert from watch to enclosing

As side effect, this should workaround the situation when HDMI audio output

requires manual user intervention to make sound working. If at some point
this won't be enough, we can try to fetch some additional priority flags
