5182703cc8 Flush cached access mode after modifying a files attributes for
NFSv3. It's likely that modifying the attributes will affect the
file's accessibility. This version of the patch is one suggested
by Ian Dowse after reviewing my original attempt in the PR

9c5d31dff2 Give find(1) the option -acl to locate files with extended
ACLs.  This is similar to what ls(1) can do.  It is handy to
have it so that it can be used in conjunction with
"-exec setfacl {} \;" (to find(1)), among others.

This is the submitter's patch, but slightly modified.

263377339c Stop iterating over ACLs if we've already determined we
will print them (i.e., number of successful calls to acl_get_entry()
exceeds 3).  This makes O(1) what was O(num_TYPE_ACCESS_ACLs).

fdcac92868 Assign thread IDs to kernel threads. The purpose of the thread ID (tid)
is twofold:
1. When a 1:1 or M:N threaded process dumps core, we need to put the
   register state of each of its kernel threads in the core file.
   This can only be done by differentiating the pid field in the
   respective note. For this we need the tid.
2. When thread support is present for remote debugging the kernel
   with gdb(1), threads need to be identified by an integer due to
   limitations in the remote protocol. This requires having a tid.

To minimize the impact of having thread IDs, threads that are created
as part of a fork (i.e. the initial thread in a process) will inherit
the process ID (i.e. tid=pid). Subsequent threads will have IDs larger
than PID_MAX to avoid interference with the pid allocation algorithm.
The assignment of tids is handled by thread_new_tid().

The thread ID allocation algorithm has been written with 3 assumptions
in mind:
1. IDs need to be created as fast a possible,
2. Reuse of IDs may happen instantaneously,
3. Someone else will write a better algorithm.

b08f499b32 Fixed a few bugs in the rl(4) driver:
Under polling(4), we counted non-existent output packets and wasted
CPU cycles, corrected.  (PR kern/64975.)

The fix in revision 1.71 to correct resetting of the watchdog timer
was wrong.

In rl(4), the TX list does not have a gap between the consumer and
producer, so the "empty TX list" test was wrong, corrected.

Also, resetting the timer to five each time we know there is still
some TX work to do was a bad idea -- under polling(4), if the chip
goes out to lunch, this results in the watchdog routine to _never_
be called.  Instead, let the timer downgrade to zero and fire the
watchdog, then reset it to five when it is zero AND there is some
TX work left.  (Most other network drivers need this fix too.)

6ec31f009a Performance tuning.
Moved the RX ring resyncing code to ste_rxeoc(), and only run it
if we were asked to POLL_AND_CHECK_STATUS, under DEVICE_POLLING.
(This significantly reduces the CPU load.)

Improved the RX ring resyncing code by re-checking if the head
is still empty before doing resyncing.  This mostly affects the
DEVICE_POLLING mode, where we run this code periodically.  We
could start checking with an empty head (well, an empty ring
even), and after doing a few iterations, the chip might write
a few entries, including the head, and we would bogusly consider
this case as requiring resyncing.  On a test box, this reduced
the number of resyncs done by a factor of 10.

In ste_txeof(sc), only reset the watchdog timer to zero when
the TX list is completely empty.

Converted ste_tx_prev_idx to a pointer -- faster.

Removed some bitrot.

36c6538b7f Change handling of probe response frames. Previously we always dropped the
refcnt on the node but left it in the node table.  This allows the node table
to hold the results of scanned ap's but for ibss scans left nodes w/o any
driver-private state setup and/or a bad refcnt (when the nodes were timed
out they were prematurely discarded).  Now we treat nodes identified for ap
scanning as before but force nodes discovered when scanning for ibss neighbors
to have complete/proper state and hold the refcnt on the node.  Any other
nodes created because of these frames are discarded directly (need to optimize
this case to eliminate various work that's immediately discarded).

7b09c33a9f Note previous commit also purges all node table entries collected while
do scanning when operating in adhoc mode.  This is necessary to insure
nodes in the table have a correct refcnt and driver-private state but is
suboptimal. A better solution is to probe undiscovered neighbors and use
the probe response to do the right thing (support for that comming in a
separate commit).

o remove IEEE80211_C_RCVMGT capability
o on transmit craft new nodes as needed using new ieee80211_find_txnode routine
o add ieee80211_find_txnode routine to lookup a node by mac address and
  if not present create one when operating in ibss/ahdemo mode; new nodes
  are dup'd from bss and the driver is told to treat the node as if a new
  association has been created so driver-private state (e.g. rate control
  handling) is setup

34b678a695 Rearrangements needed for syscons(4) to be used as a console device
on architectures that need to call cninit() before the machine is
ready to support mutexes (required by make_dev()).

	- Remove make_dev() call from scinit() when flags indicate
	  unit is the system console, rely on sc_attach_unit() to
	  handle it.
	- When trying to access current screen's status (scr_stat
	  structure) use the static one provided for the initial
	  system console if no dev_t is available.
	- When calling make_dev() in sc_attach_unit() catch special
	  case of system's initial console and set up dev_t structure
	  to include pointer to console's scr_stat struct.
