A similar note is already present in the description of the
ntpd_sync_on_start variable.
This patch adds a note to the description of the ntpdate_enable variable.
This way it would be easier to spot. Otherwise a user might skip the part
of the manual describing ntpd_sync_on_start if they stop reading after
learning about ntpdate_enable.

PR#230752 shows a panic where an nfsd thread tries to do soconnect() on
the AF_LOCAL socket used by the nfsuserd while already holding an
exclusive lock on it. I am not 100% sure how this happens, but since an
AF_LOCAL socket is in the file system namespace it is conceivable that it
could lock it and then attempt an upcall to the nfsuserd.
However, reverting r320757 stops the nfsuserd from using an AF_LOCAL
socket, so it should avoid any such panic().
r320757 did fix a problem with running the nfsuserd when jails were
enabled, but that can be dealt with less elegantly by allowing the
use of an alternate address instead of 127.0.0.1.
The gssd daemon also uses an AF_LOCAL socket, but it will do upcalls
before the nfsd thread processes the RPC, so I think it should not
be suseptible to this problem.

This way the target fails if unifdef doesn't exist or doesn't modify the
file instead of just generating an empty .c file.
I found this while building without inherited $PATH (D16815)
Approved By: jhb (mentor)
The current invocation of unifdef causes the build to fail when using a shell
with -o pipefail on by default since unifdef will return a non-zero exit status
if it changes something. The only thing this call to unifdef does is remove 5
lines that will be ignored by the compiler anyway. Furthermore, it is the only
make rule in the source tree that requires unifdef. Removing this call also
makes it slightly easier to build without inhering $PATH (D16815) since we
don't need unifdef anymore.
I also noticed that the sed call to replace the include guard has been broken
for over 10 years since the import of expat 2.0.1 changed it from
`XmlParse_INCLUDED` to `Expat_INCLUDED`. I could also fix this but since it's
been broken for so long and no one noticed, it's probably not necessary.

Also fix file descriptor leak.

Once a group is skipped we can clear the update flag on all the members.

The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).
This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.
This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.

This includes some light rework to simplify the line parsing, as well. If
we hit a line match, we'll always either use the line and move on to the
next line, or we'll spew out malformed line errors.
We had multiple spots to output the error and set the status based on
whether we had a non-nil first capture group or failed EOL validation, but
it was always the same error. Light rework entails a small label jump to
skip error handling and elimination of 'found' local.
As discussed on the MLs drm2 conflicts with the ports' version and there
is no upstream for most if not all of drm. Both have been merged in to
a single port.
Users on powerpc, 32-bit hardware, or with GPUs predating Radeon

other users should be able to use one of the LinuxKPI-based ports:

A couple of issues addressed:
1.) Modules with - in the name were not recognized as modules
2.) The module regex was repeated for each place a module name may appear
3.) The 'strip leading space' bits were repeated for each expression
4.) The trailing 'comment validation' stuff was repeated every expression
#4 still has some more work to be done. exec lines, for instance, don't
capture a 'value' -- there's only one capture pattern. This throws off the
'c' value that we match, so the trailing bits aren't *actually* being
validated. This isn't a new issue, though, so a future comit will address
this.
Prevent some classes of foot-shooting that may result in permissions

Reported by: Michal Meloun <melounmichal@gmail.com>
In pre-SMPng, the global 'imen' was used to track mask state of the
hardware interrupts and was aligned to the masks used by spl*().
When the atpic code was converted to using the x86 interrupt source
abstraction, the global 'imen' was preserved by having each PIC
instance point to an invididual byte in the global 'imen' to hold its
8-bit interrupt mask. The global 'imen' is no longer used for
anything however, so rather than storing pointers in 'struct atpic',
just store the individual 8-bit mask for each PIC as a char.
While here, convert the ATPIC macro to using C99 initializers.

r329759 introduced this parameter, which controls the rate at which ZFS
UMA zones are drained when the ARC reclaim thread is shrinking the ARC.
The reclamation target is derived from the global free page count, and
arc_shrink() only frees buffers back to UMA, so the free page count is
not updated until the zones are drained. Thus, back-to-back calls to
arc_shrink() within the arc_kmem_cache_reap_retry_ms interval do not
provide immediate feedback to the arc_reclaim control loop, so we may
free more of the ARC than needed to address a transient page shortage.
As we do not implement the asynchronous zone draining added in r329759,
disable the retry interval, restoring pre-r329759 behaviour. That is,
we will drain the ZFS UMA zones before each attempt to shrink the ARC.
