- Avoid looping forever if a concurrent reset causes a read of the
interrupt status register to return all ones.
- Lock the softc before reading the interrupt status, so as to avoid a
similar infinite loop in hdac_one_intr().
This fixes suspend-to-S3 on some laptops.

Some loops access the fd table of a different process, and drop the
filedesc lock while iterating, so they check the table's refcount.
However, we access the table before the first iteration, in order to get
the number of table entries, and this access can be a use-after-free.
Fix the problem by checking the refcount before we start iterating.

A NFSv4.1/4.2 pNFS mount needs to do a
separate Open+LayoutGet RPC, so do not do
a Lookup+Open RPC for these mounts.
The Lookup+Open RPCs are still disabled,
until further testing is done, so this patch
has no effect at this time.
There's too many broken hardware out there that wrongly has the
ACPI_FADT_NO_VGA bit set. Ignore it unless running as a virtualized
guest, as then the expectation would be that the hypervisor does
provide correct ACPI tables.

Commit 0455cc7104 broke snapshotting for ffs. In that commit,
ffs_mount() was changed so the namei() lookup for a disk device happens
before ffs_snapshot(). This caused the issue where namei() would lookup
the snapshot file and fail because the file doesn't exist. Even if it did
exist, taking a snapshot would still fail since it's not a disk device.
Fix this by taking a snapshot of the filesystem as-is and return without
altering ro/rw or any other attributes that are passed in.

As an unwanted side effect of the performance improvements in
24f0bfbad5, epair interfaces stop forwarding traffic on higher
load levels when running on multi-core systems.
This happens due to a race condition in the logic that decides when to
place work in the task queue(s) responsible for processing the content
of ring buffers.
In order to fix this, a field named state is added to the epair_queue
structure. This field is used by the affected functions to signal each
other that something happened in the underlying ring buffers that might
require work to be scheduled in task queue(s), replacing the existing
logic, which relied on checking if ring buffers are empty or not.
epair_menq() does:
- set BIT_MBUF_QUEUED
- queue mbuf
- if testandset BIT_QUEUE_TASK:
enqueue task
epair_tx_start_deferred() does:
- swap ring buffers
- process mbufs
- clear BIT_QUEUE_TASK
- if testandclear BIT_MBUF_QUEUED
enqueue task

for missing devices.
The fsck_ffs(8) utility uses its internal function openfilesys()
when opening a disk to be checked. This change avoids the use
of pfatal() in openfilesys() which always exits with failure (exit
value 8) so that the caller can choose the correct exit value.
In the case of a non-existent device it should exit with value 3
which allows the startup system to wait for drives (such as those
attached by USB) to come online.
