c6a1972441 install: Revert utimensat usage (r299850).
This should fix the build on older stable/10, since install is a bootstrap
tool.

Pending a decision how to fix this properly, revert utimensat usage. Copies
with the -p option will again appear older than the original almost always,
but -p is not commonly used.

88211e07b7 fix a vnode reference leak caused by illumos compat traverse()
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

58f81b7be8 Add support for intrng to arm64. As the GICv3 drivers will need to be
updated, and until further testing can be done, this is disabled for now.

It is expected arm64 will switch to this interface, and the old interface
will be removed before 11.0 is released.

61d083eeda Re-commit r299467 having fixed the build:
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.

f1a8e245ae Introduce MSI and MSI-X support to intrng. This adds a new msi device
interface with 5 methods to mirror the 5 MSI/MSI-X methods in the pcib
interface. The pcib driver will need to perform a device specific lookup
to find the MSI controller and pass this to intrng as the xref. Intrng
will finally find the controller and have it handle the requested operation.

65bf368323 dounmount: do not call mountcheckdirs() for mounts with MNT_IGNORE
This is a bit hackish, but the flag is currently set only for ZFS
snapshots mounted under .zfs.  mountcheckdirs() can change cdir/rdir
references to a covered vnode.  But for the said snapshots the covered
vnode is really ephemeral and it must never be accessed (except
for a few specific cases).

To do:	consider removing mountcheckdirs() entirely

It only supports 802.1q VLANs and doesn't support external PHYs at the

1c1d616948 zfsctl_snapdir_lookup: always clear VV_ROOT flag of snapshot's root VV_ROOT
Previosuly we did that only if the snapshot was mounted earlier, its
root vnode got recycled and then we accessed it again.
We never cleared the flag for a freshly mounted snapshot.

That was very inconsistent and probably a source of some bugs.
Or maybe that painted over some bugs which might get revealed now.

We should consistently clear the flag because we try very hard to
pretend that snapshots auto-mounted under .zfs are part of their
original filesystem.  In other words, we try to hide the fact that they
are different filesystems / mountpoints.

c6df178a61 zfsctl: fix several problems with reference counts
* Remove excessive references on a snapshot mountpoint vnode.
  zfsctl_snapdir_lookup() called VN_HOLD() on a vnode returned from
  zfsctl_snapshot_mknode() and the latter also had a call to VN_HOLD()
  on the same vnode.
  On top of that gfs_dir_create() already returns the vnode with the
  use count of 1 (set in getnewvnode).
  So there was 3 references on the vnode.

* mount_snapshot() should keep a reference to a covered vnode.
  That reference is owned by the mountpoint (mounted snapshot filesystem).

* Remove cryptic manipulations of a covered vnode in zfs_umount().
  FreeBSD dounmount() already does the right thing and releases the covered
  vnode.
