0ef16b090a Resort copyrights and licenses in kern_acct.c: per UCB letter,
the UCB license now excludes the advertising clause.  I'm not
interested in it either, so move my copyright.  This leaves
only a CGD copyright with the advertising clause.

12b187d035 Fix potential node refcnt leak. If mbufs are q'd on ic_mgtq when
the state machine clocks to INIT, node references are not reclaimed.
Add a new routine ieee80211_drain_ifq that does this and use it
instead of IF_DRAIN.

fae048c859 Correct several issues with rate set negotiation:
o add IEEE80211_F_JOIN flag to ieee80211_fix_rate to indicate a station
  is joining a BSS; this is used to control whether or not we over-write
  the basic rate bit in the calculated rate set
o fix ieee80211_fix_rate to honor IEEE80211_F_DODEL when IEEE80211_F_DONEGO
  is not specified (e.g. when joining an ibss network)
o on sta join always delete unusable rates from the negotiated rate set,
  this was being done only ibss networks but is also needed for 11g bss
  with mixed stations
o on sta join delete unusable rates from the bss node's rate set, not the
  scan table entry's rate set
o when calculating a rate set for new neighbors in an ibss caculate a
  negotiated rate set so drivers are not presented with rates they should
  not use

6d67972dc5 o Changes to psycho_attach(): [1]
- Clear the PCI AFSR and status error bits as previous errors still
    might be indicated.
  - Set up the PCI control and diagnostic registers according to the
    capabilities, workarounds, etc of/for specific revisions of the
    supported bridges. This includes no longer setting Hummingbird-/
    Sabre-specific bits in the PCI control register but preserving
    what the firmware has initialized them to like OpenSolaris does.
    Previously we were setting these bits according to the example in
    the Sabre documentation, which I doubt is appropriate for all
    Sabre based designs and especially not for Hummingbirds. This
    also includes not enabling bus parking unless the firmware tells
    us to.
  - Set the PCI latency timer register as this isn't always done by
    the firmware.
o Remove a redundant argument from psycho_set_intr() and in this
  function check the return value of bus_setup_intr(). [2]
o Let psycho_setup_intr() return ENOMEM instead of 0 when it can't
  allocate memory for the interrupt wrapper stub and EINVAL instead
  of 0 if it can't find the interrupt vector in the interrupt map.
o Add a workaround for a bug of the Sabre-APB-combination where it
  doesn't drain DMA write data for devices behind additional PCI-PCI
  bridges underneath the APB PCI-PCI bridge. This workaround (do
  things necessary in order to achieve a manual drain when coherency
  is required) is currently implemented in psycho_setup_intr() and
  psycho_intr_stub() (for easy MFC'ing) and therefore is only applied
  for interrupt handlers. This should be moved to psycho(4)-specific
  bus_dma_tag_create() and bus_dmamap_sync() methods, respectively,
  once this driver is converted to make use of BUS_GET_DMA_TAG(), so
  the workaround is also applied for polling(4) callbacks. [3]
o Fix some minor style issues.

384c6b86d0 In ofw_pcibus_attach() skip dupe PCI devices reported by the
firmware (mainly 'pmu' and its 'lomp' dupe found in a couple of
later USII{e,i}-based machines) by checking whether a device with
the same triple of bus number, slot and function already has been
added. This is the simple yet effective approach introduced in
OpenBSD some time ago, but which has the flaw that it assumes
that the device and its dupe(s) found in the OFW device tree are
equal or at least the one encountered first is in some way the
more important one (this is the case with 'pmu' and 'lomp'; the
'pmu' node has couple of properties and children while the 'lomp'
one misses most of these). If there's ever a device/dupe pair
where we don't encounter the more important node first, we'll
probably need to introduce a quirk list in order to add the
desired device but prevent its dupe(s) from being added.

c72796ebf4 Don't rely on GM_GP_CTRL register contents when mii(4) layer reports
link state changes. Instead, build new speed/duplex/flow-control
settings from the values reported from PHY.
This should fix speed/duplex/flow-control mismatches between GMAC and
PHY which resulted in very poor Rx performance due to lots of
out-of-order packet delivery.

198bd4c0fc Re-work Cx handling to be per-cpu and asymmetrical, fixing support on
modern dual-core systems as well.

- Parse the _CST packages for each cpu and track all the states individually,
on a per-cpu basis.

- Revert to generic FADT/P_BLK based Cx control if the _CST package
is not present on all cpus. In that case, the new driver will
still support per-cpu Cx state handling. The driver will determine the
highest Cx level that can be supported by all the cpus and configure the
available Cx state based on that.

- Fixed the case where multiple cpus in the system share the same
registers for Cx state handling. To do that, added a new flag
parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that
enable the caller to add the RF_SHAREABLE flag.  This flag could also be
useful to other callers (acpi_throttle?) in the tree but this change is
not yet made.

- For Core Duo cpus, both cores seems to be taken out of C3 state when
any one of the cores need to transition out. This broke the short sleep
detection logic.  It is disabled now if there is more than one cpu in
the system for now as it fixed it in my case.  This quirk may need to
be re-enabled later differently.

- Added support to control cx_lowest on a per-cpu basis. There is still
a generic cx_lowest to enable changing cx_lowest for all cpus with a single
sysctl and for ease of use.  Sample output for the new sysctl:

dev.cpu.0.cx_supported: C1/1 C2/1 C3/57
dev.cpu.0.cx_lowest: C3
dev.cpu.0.cx_usage: 0.00% 43.16% 56.83%
dev.cpu.1.cx_supported: C1/1 C2/1 C3/57
dev.cpu.1.cx_lowest: C3
dev.cpu.1.cx_usage: 0.00% 45.65% 54.34%
hw.acpi.cpu.cx_lowest: C3

b5a0929368 Extend the emu10kx driver. With the words of the author:
---snip---
New features:
1.	Optional multichannel recording (32 channels on Live!, 64 channels
 	on Audigy).

 	All channels are 16bit/48000Hz/mono, format is fixed.
 	Half of them are copied from sound output, another half can be
 	used to record any data from DSP. What should be recorded is
 	hardcoded in DSP code. In this version it records dummy data, but
 	can be used to record all DSP inputs, for example..

 	Because there are no support of more-than-stereo sound streams
 	multichannell stream is presented as one 32(64)*48000 Hz 16bit mono
 	stream.

 	Channel map:

 	SB Live! (4.0/5.1)

Fixes:
1.	Do not assign negative values to variables used to index emu_cards
 	array. This array was never accessed when index is negative, but
 	Alexander (netchild@) told me that Coverity does not like it.
 	After this change emu_cards[0] should never be used to identify
 	valid sound card.
2.	Fix off-by-one errors in interrupt manager. Add more checks there.
3.	Fixes to sound buffering code now allows driver to use large playback
 	buffers.
4.	Fix memory allocation bug when multichannel recording is not
 	enabled.
5.	Fix interrupt timeout when recording with low bitrate (8kHz).

Hardware:
1.	Add one more known Audigy ZS card to list. Add two cards with
 	PCI IDs betwen old known cards and new one.

Other changes:
1.	Do not use ALL CAPS in messages.

Incomplete code:
1.	Automute S/PDIF when S/PDIF signal is lost.

Tested on i386 only, gcc 3.4.6 & gcc41/gcc42 (syntax only).
---snip---

This commits enables a little bit of debugging output when the driver is
loaded as a module. I did a cross-build test for amd64.

The code has some style issues, this will be addressed later.

The multichannel recording part is some work in progress to allow playing
around with it until the generic sound code is better able to handle
multichannel streams.

This is supposed to fix

  and clears the flag when it is finished.  fdrop() checks to see if the
  flag is set on a file descriptor whose refcount just dropped to 0 and
  waits for unp_gc() to clear the flag before completely destroying the
  file descriptor.
