86e10a0c6a Fix r273112: do not turn DROP_EN by default.
Due to adapter->hw.fc.requested_mode is filled with default value
after ixgbe_initialize_receive_units(), this leads to enabling
DROP_EN in most cases.

adcdc8f290 Convert the callouts back to using mutexes.
I did this wrong - I should've included a state flag for each callout
to see if it was supposed to run or not.  I didn't do that.
Instead, just use mutexes anyway.

61691153bd Remove dpt_isa.c and commented out references to it. It was never connected
to the build in either sys/conf/files* or sys/modules/dpt/Makefile.  Also,
it was denoted as "doesn't quite work yet" when the file was initially added
(which may account for it never having been hooked up to the build).

6e646651d3 Remove the no-at variants of the kern_xx() syscall helpers. E.g., we

kern_openat().

This removes one (sometimes two) levels of indirection and

05c4567dd9 Fix some bad interaction between cxgbe(4) and lacp lagg(4) that could
leave a port permanently disabled when a copper cable is unplugged and
then plugged right back in.

lacp_linkstate goes looking for the current ifmedia on a link state
change and it could get stale information from cxgbe(4) on a module
unplug followed by replug.  The fix is to process module events before
link-state events within the driver, and to always rebuild the ifmedia
list on a module change event (instead of rebuilding it lazily).

Thanks to asomers@ for the problem report and detailed analysis to go
with it.

Instead of waiting for empty TX FIFO it is more reasonable to
block on full FIFO. As soon as FIFO slot is free the character
can be transmitted.
In case of TX FIFO disabled, TXFF bit indicates that transmit

2da2ade021 Use the correct device (child) when asking the bus layer about which power
state said device should go into.

This was a snafu introduced in the ACPI/PCI awareness separation.

When putting a device into a power state, the bus (and thus firmware,
eg ACPI) should be asked before hand to check whether the device
can indeed go into that power state.

There's a set of nodes in ACPI under each device - the _SxD nodes - which
state which ACPI power state to put the device into when the system is
going into power save state 'x'.  So when going into S3, the existence
of an _S3D node would override whatever the system was trying to do.

By default the PCI code wants to put devices into D3 before suspending.

I have a laptop here (Asus Zenbook - check the PR) whose EHCI controller
really wants to be in D2 during suspend, not D3.  So if we put it into
D3 and then try to enter S3, everything hangs.  The device itself
can go into D3 - it just can't be there when the call to ACPI to enter
S3 occurs.  The PCI patch fixes this.

jkim@ noticed that the same is needed for the ACPI child device
enumeration.

Thankyou to Matt Dillon (the programmer, not the actor) for buying me
this particular laptop so I could debug the issues with the Atheros
AR9485 that is in it.  It's his fault that I ended up with this
laptop and was sufficiently annoyed by the lack of USB suspend
to go down this rabbit hole.

Tested:

* Thinkpad T400
* Thinkpad X230
* Thinkpad T42
* Thinkpad T60
* Asus Zenbook (see PR)
* Asus EEEPC 701
* Asus EEEPC 1001PX

TODO:

* Figure out what we should do about devices we unload drivers for
  that want to be in a specific state when entering S3 / S4 -
  the "put devices into D3 if they're not bound to a driver" option
  may also mess with things.

d6fe56e5d7 Based on some BIOS configuration (GGC register in host bridge, bit 1),
IGP may declare subclass as either VGA-compatible, or non-VGA.  The
difference is that in the later case, IGP does not claim VGA cycles.
Other than that, the device functions normally, and agp_i810 should
attach to it.

5ebb15b942 Add missing privilege check when setting the dump device. Before that change it
was possible for a regular user to setup the dump device if he had write access
to the given device. In theory it is a security issue as user might get access
to kernel's memory after provoking kernel crash, but in practise it is not
recommended to give regular users direct access to storage devices.

Rework the code so that we do privileges check within the set_dumper() function
to avoid similar problems in the future.

  - Provide emergency write feature description. Note that QEMU

  - Make the VTCON_FLAG_* defines sequential once again.
  - When the multiple port feature is not negotiated, query the
    rows and columns of the one console during the device attach
    when the size feature is negotiated.
  - Report failure to the device if hot plugging a port fails.
  - Acknowledge the console port event with an open event. This
    is required by the spec, but QEMU doesn't seem to care.
