riastradh | virtio@acpi, virtio@fdt: Nix DVF_DETACH_SHUTDOWN.
There is no reason to force _all_ devices attached at the virtio bus
to detach at shutdown. This only makes sense for devices that
require detach in order to force buffered writes to persistant
storage so we don't lose them (or, in principle, require detach in
order to release hardware resources).
And the only virtio devices I found that require detach-on-shutdown,
namely scsi@virtio, already set DVF_DETACH_SHUTDOWN, so there's no
need for the bus to do it. (The only other obvious case, ld@virtio,
uses a pmf shutdown handler instead of detach, so it doesn't need
DVF_DETACH_SHUTDOWN.)

yamaguchi | branches: 1.10.10;
rename "setup_interrupts" to "alloc_interrupts"
in virtio_mmio and virtio_acpi
This should fix build failure on evbarm.

Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

reinoud | Remove the virtio child driver finalisation check KASSERT that, while it
should never trigger, a possible bug in a child driver shouldn't have to panic
the kernel. Instead report the internal error.

reinoud | Add VirtIO PCI v1.0 attachments and fix the drivers affected.
The vioif, ld, scsi, viornd and viomb devices were adjusted when needed and
tested both in legacy 0.9 and v1.0 attachments trough PCI on amd64, sparc64,
aarch64 and aarch64-eb. ACPI/FDT attachments also tested on
aarch64/aarch64-eb.
Known issues
* viomb on aarch64 works only with ACPI/FDT attachment but not with PCI
attachment. PCI and ACPI/FDT attachment works on aarch64-eb.
* virtio on sparc64 attaches but is it not functioning though not a
regression.

jmcneill | Fix 32-bit build.

skrll | branches: 1.3.2;
Use the 64bit DMA tag if its valid.
There appears to be a bug in virtio / ld_virtio and bounce buffers that
was triggered when the bus_dmatag_subregion code on arm64 was fixed to
correctly create a new tag for the 32bit tag vs the system (64bit) tag.
This change avoids the bug.
