Centralizes fetching of board information (vendor, type, revision, etc),
and adds support for matching quirks against board identification info.
* Adds a BHND_BUS_READ_BOARD_INFO(), allowing bhnd bus/bus parent(s) to
handle implementation-specific fetching of board info.
* Integrates board type constants from the latest Broadcom ISC-licensed
bcmdevs.h included in dd-wrt's Broadcom driver source drops.
* Adds support for matching on chip/board quirks to bhnd_device_quirks()/
bhnd_chip_quirks().

This patch fix trampoline build. inckern.S increases stack and calls _startC
of elf_trampoline, so inckern.S should be called before elf_trampoline. gcc4.2 puts
text (code) into image according to order of source files in this call, so order has changed.
In addition make will install trampoline kernel. It allows to use kernel for firmware build.

Some ACPI operations such as mutex acquires and event waits accept a
timeout. The ACPI OSD layer implements these timeouts by using regular
sleep timeouts. However, this doesn't work during early boot before
event timers are setup. Instead, use polling combined with DELAY()
to spin.
This fixes booting on upcoming Intel systems with Kaby Lake processors.

That was just wrong. In fact, we can safely keep this static entry when
it's inactive.
Now the destructive action is moved to the reclaim method and the
function is renamed from zfsctl_snapdir_inactive(0 to
zfsctl_snapdir_reclaim().
Also, we can use gfs_vop_reclaim() instead of gfs_dir_inactive() +
kmem_free().
Lastly, we can just assert that the node does not any children when it
is reclaimed, even on the force unmount. That's because zfs_umount()
does an extra vflush() pass which should destroy all snapshot-mountpoint
vnodes that are the snapdir's children.
MFC after: 5 weeks
Those vnodes should not linger. "Stale" nodes may get out of
synchronization with actual snapshots. For example if we destroy a
snapshot and create a new one with the same name. Or when we rename a
snapshot.
While there fix the argument type for zfsctl_snapshot_reclaim().
Also, its original argument can be passed to gfs_vop_reclaim() directly.

that. Referencing just in case.

Dropping the root vnode's lock after VFS_ROOT() didn't really help the
fact that we acquired the lock while holding its child's, .zfs, lock
while performing the operaiton.
So, directly use zfs_zget() to get the root vnode.
While there simplify the code in zfsctl_freebsd_root_lookup.
We know that .zfs is always exclusively locked.
We know that there is already a reference on *vpp, so no need for an
extra one.
Account for the fact that .. lookup may ask for a different lock type,
not necessarily LK_EXCLUSIVE. And handle a possible failure to acquire
the lock given the lock flags.
MFC after: 5 weeks
In fact, that was dangerous. For example, zfsctl_snapshot_reclaim()
calls gfs_dir_lookup() on ".." path and that ends up calling
gfs_lookup_dot() which violated locking order by acquiring the parent's
directory vnode lock after the child's vnode lock.
Also, the previous behavior was inconsistent as gfs_dir_lookup()
returned a locked vnode for . and .. lookups, but not for any other.
Now gfs_lookup_dot() just references a resulting vnode and the locking
is done in its consumers, where necessary.
Note that we do not enable shared locking support for any gfs / zfsctl
vnodes.
This commit partially reverts r273641.
MFC after: 5 weeks
The former acquired a snap vnode lock while holding sd_lock while the
latter does the opposite.
The solution is drop sd_lock before acquiring the vnode lock. That
should be okay as we are still holding a lock on the 'snapshot'
directory in the exclusive mode. That lock ensures that there are no
concurrent lookups in the directory and thus no concurrent mount attempts.
But now we have to account for the possibility that the snap vnode
might get reclaim after we drop sd_lock and before we can get
the node lock. So, check for that case and retry.

This commit partially reverts r273641 which introduced the leak.
It did so to accomodate for some consumers of traverse() that expected
the starting vnode to stay as-is. But that introduced the leak in the
case when a mounted filesystem was found and its root vnode was
returned.
r299914 removed the troublesome consumers and now there is no reason to
keep the starting vnode. So, now the new rules are:
- if there is no mounted filesystem, then nothing is changed
- otherwise the starting vnode is always released
- the root vnode of the mounted filesystem is returned locked and
referenced in the case of success

Add a new get_id interface to pci and pcib. This will allow us to both
detect failures, and get different PCI IDs.
For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.
For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.
A follow up commit will be made to remove pci_get_rid.
