Re-implement the DMAR I/O MMU code in terms of PCI RIDs
Under the hood the VT-d spec is really implemented in terms of
PCI RIDs instead of bus/slot/function, even though the spec makes
pains to convert back to bus/slot/function in examples. However
working with bus/slot/function is not correct when PCI ARI is
in use, so convert to using RIDs in most cases. bus/slot/function
will only be used when reporting errors to a user.
PCIe Alternate RID Interpretation (ARI) is an optional feature that
allows devices to have up to 256 different functions. It is
implemented by always setting the PCI slot number to 0 and
re-purposing the 5 bits used to encode the slot number to instead
contain the function number. Combined with the original 3 bits
allocated for the function number, this allows for 256 functions.
This is enabled by default, but it's expected to be a no-op on currently
supported hardware. It's a prerequisite for supporting PCI SR-IOV, and
I want the ARI support to go in early to help shake out any bugs in it.
ARI can be disabled by setting the tunable hw.pci.enable_ari=0.

This fixes a bug in the way that the LLE timers for nd6
and arp were being used. They basically would pass in the
mutex to the callout_init. Because they used this method
to the callout system, it was possible to "stop" the callout.
When flushing the table and you stopped the running callout, the
callout_stop code would return 1 indicating that it was going
to stop the callout (that was about to run on the callout_wheel blocked
by the function calling the stop). Now when 1 was returned, it would
lower the reference count one extra time for the stopped timer, then
a few lines later delete the memory. Of course the callout_wheel was
stuck in the lock code and would then crash since it was accessing
freed memory. By using callout_init(c, 1) we always get a 0 back
and the reference counting bug does not rear its head. We do have
to make a few adjustments to the callouts themselves though to make
sure it does the proper thing if rescheduled as well as gets the lock.

is occuring and the callout is about to expire and the
migration has been deferred, the callout_active will no
longer return true until after the migration. This confuses
and breaks callers that are doing callout_init(&c, 1); such

2) The migration code had a bug in it where when migrating, if
a two calls to callout_reset came in and they both collided with
the callout on the wheel about to run, then the second call to

would separate out direct/vs/non-direct. This is incorrect and can
cause panics as Peter Holm has found for me (Thanks so much Peter for

Pull in r201130 from upstream clang trunk (by Ted Kremenek):
Fix PCH deserialization bug with local static symbols being treated
as local extern.
This triggered a miscompilation of code using Boost's
function_template.hpp when it was included inside a PCH file. A
local static within that header would be treated as local extern,
resulting in the wrong mangling. This only occurred during PCH
deserialization.

MFC r274638:
Add basic interrupt management code to gpiobus and ofw_gpiobus.
This is the general support to allow the use of GPIO pins as interrupt
sources for direct gpiobus children.
The use of GPIO pins as generic interrupt sources (for an ethernet driver
for example) will only be possible when arm/intrng is complete. Then, most
of this code will need to be rewritten, but it works for now, is better
than what we have and will allow further developments.

MFC: r273264, r274409, r278212, r278213:
Add a workaround needed to fix a bug of Arasan Host Controller where it may
lose the contents of consecutive writes (that happens within two SD card
clock cycles).
This fixes the causes of instability during the SD card detection and
identification on Raspberry Pi (which happens at 400 kHz and so was much
more vulnerable to this issue).
Remove the previous workaround which clearly can't provide the same effect.
Remove stale comments about the issues with HS mode.
Remove a previous workaround to limit the minimum sdhci frequency that
isn't needed anymore.
Remove some duplicate calls to bus_release_resource() and destroy the mutex
on error cases.
