The salt based checksum mechanisms, such as skein, are storing the seed
in spa structure, and need to access the spa to use the seed. The current
mechanism for quick access to correct spa is via pointer provided by
vdev structure, but unfortunately the current code does set spa only
for the leaf vdev. This patch will fix the issue by making sure the
loader zfs reader will set spa also for top-level vdevs.

The gpiobus driver is attached explicitly and generally should be

The feature enables us to pass through physical PCIe devices to FreeBSD VM
running on Hyper-V (Windows Server 2016) to get near-native performance with
low CPU utilization.
The patch implements a PCI bridge driver to support the feature:
1) The pcib driver talks to the host to discover device(s) and presents
the device(s) to FreeBSD's pci driver via PCI configuration space (note:
to access the configuration space, we don't use the standard I/O port
0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V,
which is very similar to the 0xCF8/CFC method).
2) The pcib driver allocates resources for the device(s) and initialize
the related BARs, when the device driver's attach method is invoked;
3) The pcib driver talks to the host to create MSI/MSI-X interrupt
remapping between the guest and the host;
4) The pcib driver supports device hot add/remove.

We get the mapping between vcpu_id and FreeBSD kernel's cpu id when VMBus

Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages. This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.

make sure we follow the suit with trampoline as well.

Rather than printing a warning for every time we receive a fileid > 2^32
from the NFS server, count warnings and print at most one of each warning
type per minute, e.g.,
Nov 15 05:17:34 ip-172-30-1-221 kernel: NFSv4 fileid > 32bits (24730 occurrences)
Nov 15 05:17:56 ip-172-30-1-221 kernel: NFSv4 mounted on fileid > 32bits (178 occurrences)
Nov 15 05:18:53 ip-172-30-1-221 kernel: NFSv4 fileid > 32bits (7582 occurrences)
Nov 15 05:18:58 ip-172-30-1-221 kernel: NFSv4 mounted on fileid > 32bits (23 occurrences)
A buildworld with an NFS mounted /usr/obj can otherwise result in
hundreds of thousands of lines being printed, which seems unnecessarily
verbose.
When ino_t becomes a 64-bit type, these printfs will no longer be needed
(and the problems associated with truncating 64-bit fileids to generate
32-bit inode numbers will also go away).

VSS stands for "Volume Shadow Copy Service". Unlike virtual machine
snapshot, it only takes snapshot for the virtual disks, so both
filesystem and applications have to aware of it, and cooperate the
whole VSS process.
This driver exposes two device files to the userland:
/dev/hv_fsvss_dev
Normally userland programs should _not_ mess with this device file.
It is currently used by the hv_vss_daemon(8), which freezes and
thaws the filesystem. NOTE: currently only UFS is supported, if
the system mounts _any_ other filesystems, the hv_vss_daemon(8)
will veto the VSS process.
If hv_vss_daemon(8) was disabled, then this device file must be
opened, and proper ioctls must be issued to keep the VSS working.
/dev/hv_appvss_dev
Userland application can opened this device file to receive the
VSS freeze notification, hold the VSS for a while (mainly to flush
application data to filesystem), release the VSS process, and
receive the VSS thaw notification i.e. applications can run again.
The VSS will still work, even if this device file is not opened.
However, only filesystem consistency is promised, if this device
file is not opened or is not operated properly.
hv_vss_daemon(8) is started by devd(8) by default. It can be disabled
by editting /etc/devd/hyperv.conf.

Although the higher end MIPS hardware handles cache aliasing issues in
hardware, the older cores (r4k, etc) and some compile versions of the
newer cores (mips24k, mips34k, mips74k) don't have this feature.
This means we end up with some very unfortunate behaviour that was
made very obvious by some recent changes to the FFS pager by kib.
So, flip this off until we get our MIPS pmap/cache code upgraded to
handle aliased pages in software.
