da3b488d62 Move duplicate code to a new public function.
This new function can be used by other drivers to reserve the use of GPIO
pins.

Anyway, the use of ofw_gpiobus_parse_gpios() is preferred when possible.

7d69783ae4 Fix warnings/errors when building vmm.ko with gcc:
- fix warning about comparison of 'uint8_t v_tpr >= 0' always being true.

- fix error triggered by an empty clobber list in the inline assembly for
  "clgi" and "stgi"

- fix error when compiling "vmload %rax", "vmrun %rax" and "vmsave %rax". The
  gcc assembler does not like the explicit operand "%rax" while the clang
  assembler requires specifying the operand "%rax". Fix this by encoding the
  instructions using the ".byte" directive.

c92a456b55 Fix group membership of cloned interfaces when one is moved by
if_vmove().

In if_vmove(), if_detach_internal() and if_attach_internal() were
called in series to detach and reattach the interface.  When
detaching, if_delgroup() was called and the interface leaves all of
the group membership.  And then upon attachment, if_addgroup(ifp,
IFG_ALL) was called and it joined only "all" group again.

This had a problem. Normally, a cloned interface automatically joins
a group whose name is ifc_name of the cloner in addition to "all"
upon creation.  However, if_vmove() removed the membership and did
not restore upon attachment.

54eb0be231 Change the sa(4) driver to check for long position support on
SCSI-2 devices.

Some older tape devices claim to be SCSI-2, but actually do support
long position information.  (Long position information includes
the current file mark.)  For example, the COMPAQ SuperDLT1.

So we now only disable the check on SCSI-1 and older devices.

	In saregister(), only disable fetching long position
	information on SCSI-1 and older drives.  Update the
	comment to explain why.

11d8451df3 Implement Enhanced DAD algorithm for IPv6 described in
draft-ietf-6man-enhanced-dad-13.

This basically adds a random nonce option (RFC 3971) to NS messages
for DAD probe to detect a looped back packet.  This looped back packet
prevented DAD on some pseudo-interfaces which aggregates multiple L2 links
such as lagg(4).

The length of the nonce is set to 6 bytes.  This algorithm can be disabled by
setting net.inet6.ip6.dad_enhanced sysctl to 0 in a per-vnet basis.

This is a QCA9558 SoC (2ghz 3x3) with an atheros 11ac PCIe 5GHz 3x3
NIC and an AR8327 gigabit ethernet switch.

fb76025135 Bring over the initial QCA955x SoC support framework.
This is enough to bring up the basic SoC support.

What works thus far:

* The mips74k core, pll setup, and UART (or else well, stuff would
  be really difficult..)
* both USB 2.0 EHCI controllers
* on-board 2GHz 3x3 wifi (the other variant has 2GHz/5GHz wifi on-chip);
* arge0 - not yet sure why arge1 isn't firing off interrupts and thus
  handling traffic, but I will soon figure it out and fix it here.

Tested:

* AP135 reference design, QCA9558 SoC, pretending to be an 11n
  2GHz AP.

TODO:

* There's an interrupt mux hooking up devices to IP2 and IP3 - but it's
  not a read-and-clear or write-to-clear register.  So, trying to use it
  naively like I have been ends up with massive interrupt storms.
  For now the things that share those interrupts can just take them as
  shared interrupts and try to play nice.

* There's two PCIe root complexes /and/ one of them can actually be
  a PCIe device endpoint.  Yes, you heard right.  I have to teach the
  AR724x PCIe bridge code to handle multiple instances with multiple
  memory/irq regions, and then there'll be RC support, but EP support
  isn't on my TODO list.

* I'm not sure why arge1 isn't up and running.  I'll go figure that
  out soon and fix it here.

Thankyou to Qualcomm Atheros for providing me with hardware and
an abundance of documentation about these things.

There's two EHCI controllers in the QCA955x SoCs - they have different

7a49d964d3 Merge r278429 from ppc64:
Fix an extremely subtle concurrency bug triggered by running on 32-thread
POWER8 systems. During thread switch, there was a very small window when
the stack pointer was set to the stack pointer of the outgoing thread, but
after the lock on that thread had already been released.

If, during that window, the outgoing thread were rescheduled on another CPU
and begin execution and an exception were taken on the original CPU, the
trap handler and the outgoing thread would simultaneously execute on the same
stack, causing memory corruption. Fix this by making sure to release the
old thread only after cpu_switch() is done with its stack.

7190a55c3e Bump the port mask on the AR8327 ethernet switch from 0x3f to 0x7f.
So, it turns out that the AR8327 has 7 ports internally:

* GMAC0 / external (CPU) MAC0
* GMAC1 / port1 -> GMAC5 / port5: external switch port PHYs
* GMAC6 / external (CPU) MAC1

Now, depending upon how things are wired up, the second CPU port (MAC1)
can be wired to either the switch (port6), or through port5's PHY, bypassing
the GMAC+switch entirely.  Ie, it can pretend to be a boring PHY, saving
system designers from having to include a separate PHY for a "WAN" port.

Here's the rub - the AP135 board (QCA955x SoC) hooks up arge0 to
the second CPU port on the AR8327, but it's hooked up as RGMII.
So, in order to hook it up to the rest of the switch, it isn't configured
as a separate PHY - OpenWRT has it setup as connected via RGMII to
GMAC6 and (I'm guessing) it's set to be a WAN port by configuring up
port-based VLANs or something.

Thus, with a port mask of 0x3f, GMAC6 was never allowed to receive traffic
from any other port.  It could transmit fine, but not receive anything.

So, now it works enough for me to continue doing board bootstrapping.
Note, this isn't enough to make the QCA955x + AR8327 work - there's
a bunch of uncommitted work to both the platform SoC (interrupt handling,
ethernet, etc) and the ethernet switch (register access space, setup, etc)
that needs to happen.  However, this particular change is also relevant to
other SoCs, like the AR934x and AR7161, both of which can be glued to
this switch.

Tested:

* AP135 development board

TODO:

* Figure out whether I can somehow abuse another port mode to have this
  be a pass-through PHY, or whether I should just create some more boot
  time hints to explicitly set up port-based isolation so this works
  in a more useful way by default.

76e2f97656 vt(4): Add support to "downgrade" from eg. vt_fb to vt_vga
The main purpose of this feature is to be able to unload a KMS driver.

When going back from the current vt(4) backend to the previous backend,
the previous backend is reinitialized with the special VDF_DOWNGRADE
flag set. Then the current driver is terminated with the new "vd_fini"
callback.

In the case of vt_fb and vt_vga, this allows the former to pass the
vgapci device vt_fb used to vt_vga so the device can be rePOSTed.
