a61914445d When newvers.sh is run, it is possible that the svnversion
(or svnliteversion) in the current lookup path is not what
was used to check out the tree.  If an incompatible version
is used, the svn revision number is not reported in uname(1).

Run ${svnversion} on newvers.sh itself when evaluating if the
svn(1) in use is compatible with the tree.  Fallback to an
empty ${svnversion} if necessary.

With this change, svnliteversion from base is only used
if no compatible svnversion is found, so with this change,
the version of svn(1) from the ports tree is evaluated first.

any character including '\0', but our version replace escaped '\0'

I.e. fnmatch("\\", "\\", 0) should not match while fnmatch("\\", "", 0)

e7495198d5 Convert net80211 over to using if_transmit for the dispatch from the
upper layer(s).

This eliminates the if_snd queue from net80211. Yay!

This unfortunately has a few side effects:

* It breaks ALTQ to net80211 for now - sorry everyone, but fixing
  parallelism and eliminating the if_snd queue is more important
  than supporting this broken traffic scheduling model. :-)

* There's no VAP and IC flush methods just yet - I think I'll add
  some NULL methods for now just as placeholders.

* It reduces throughput a little because now net80211 will drop packets
  rather than buffer them if the driver doesn't do its own buffering.
  This will be addressed in the future as I implement per-node software
  queues.

Tested:

* ath(4) and iwn(4) in STA operation

9d2f243aa6 MFV r254071:
Fix a regression introduced by fix for Illumos bug #3834.  Quote from
Matthew Ahrens on the Illumos issue:

ztest fails this assertion because ztest_dmu_read_write() does
        dmu_tx_hold_free(tx, bigobj, bigoff, bigsize);
and then
    dmu_object_set_checksum(os, bigobj,
        (enum zio_checksum)ztest_random_dsl_prop(ZFS_PROP_CHECKSUM), tx);

If the region to free is past the end of the file, the DMU assumes that there
will be nothing to do for this object.  However, ztest does set_checksum(),
which must modify the dnode.  The fix is for ztest to also call

    dmu_tx_hold_bonus(tx, bigobj);

so we can account for the dirty data associated with setting the checksum

5b596f0f5f Don't emit a spurious EVFILT_PROC event with no fflags set on process exit
if NOTE_EXIT is not being monitored.  The rationale is that a listener
should only get an event for exit() if they registered interest via
NOTE_EXIT.  This matches the behavior on OS X.
- Don't save the exit status on process exit unless NOTE_EXIT is being
  monitored.
- Add an internal EV_DROP flag that requests kqueue_scan() to free the
  knote without signalling it to userland and use this when a process
  exits but the fflags in the knote is zero.

449c2e92c9 Split the pagequeues per NUMA domains, and split pageademon process
into threads each processing queue in a single domain.  The structure
of the pagedaemons and queues is kept intact, most of the changes come
from the need for code to find an owning page queue for given page,
calculated from the segment containing the page.

The tie between NUMA domain and pagedaemon thread/pagequeue split is
rather arbitrary, the multithreaded daemon could be allowed for the
single-domain machines, or one domain might be split into several page
domains, to further increase concurrency.

Right now, each pagedaemon thread tries to reach the global target,
precalculated at the start of the pass.  This is not optimal, since it
could cause excessive page deactivation and freeing.  The code should
be changed to re-check the global page deficit state in the loop after
some number of iterations.

The pagedaemons reach the quorum before starting the OOM, since one
thread inability to meet the target is normal for split queues.  Only
when all pagedaemons fail to produce enough reusable pages, OOM is
started by single selected thread.

Launder is modified to take into account the segments layout with
regard to the region for which cleaning is performed.

Based on the preliminary patch by jeff, sponsored by EMC / Isilon
Storage Division.

872d995f76 Change the pmap_ts_referenced() method of amd64 pmap to use shared
pvh_global_lock.  This allows the method to be executed in parallel,
avoiding undue contention on the pvh_global_lock for the multithreaded
pagedaemon.

The pmap_ts_referenced() function has to inspect the page mappings for
several pmaps, which need to be locked while pv list lock is owned.
This contradicts to the lock order, where pmap lock is before pv list
lock.  Introduce the generation count for the pv list of the page or
superpage, which indicate any change in the pv list, and, as usual,
perform restart of the iteration if generation changed while pv lock
was dropped for blocking acquire of a pmap lock.
