218fe3f1b0 Use kenv -q to extract dumpdev rather than kenv, in order to avoid
spamming the console in the event that a loader tunable 'dumpdev'
isn't defined, which is not a relevant failure to report.

c3ee3aa526 Use smaller names. The "NE2000 PCI Ethernet" is largerly redundant
with edX at pciY.  This removes 8*22 bytes from the strings. Not a

e88c48fefc Add the olicom OC2231 and OC2232 to the list of cards that we should
attach to.  These cards are combo cards (in that they have a modem
inside of them), but not true MFC cards.  Full support of these cards
will have to wait until we can pick the config to use and for the PFC
support that I have brewing.

447bbaa2cf Trim down now (believed to be) unused fifo_ioctl() and
fifo_kqfilter() VOP implementations, since they in theory are used
only on open file descriptors, in which case the ioctls are via
fifo_ioctl_f() and kqueue requests are via fifo_kqfilter_f().
Generate warnings if they are entered for now.  These printf()
calls should become panic() calls.

Annotate and re-implement fifo_ioctl_f(): don't arbitrarily
forward ioctls to the socket layer, only forward the ones we
explicitly support for fifos.  In the case of FIONREAD, don't
forward the request to the write socket on a read-write fifo, or
the read result is overwritten.  Annotate a nasty case for the
undefined POSIX O_RDWR on fifos, in which failure of the second
ioctl will result in the socket pair being in an inconsistent
state.

Assert copyright as I find myself rewriting non-trivial parts of
fifofs.

1c3c40d4c0 Restructure fifo_io event-related tests in order to support test cases
relating to O_RDWR file descriptors, which while not defined in POSIX,
are in fact used:

(1) Revise assumption that we have two file descriptors when testing I/O
    operations on a fifo.  Provide cleanup routines that handle either
    two or three file descriptors (including a kqueue descriptor).

(2) Add an openfifo_rw() routine to supplement openfifo().

(3) kqueue_setup() now configures an existing kqueue to monitor a new
    file descriptor, rather than allocating a new kqueue to monitor two
    existing file descriptors.

(4) Wrap all direct poll/select/kqueue/FIONREAD interactions in a single
    function, assert_status(), which takes a file descriptor, kqueue
    descriptor, assertion of read/writable/exception states, and
    test description, then tests the assertion.  This reduces the bulk
    of calls in many of the tests, making them shorter, more readable,
    and easier to determine correct.

(5) Add a new test_events_rdwr() function, which performs a basic create/
    write/read event test on a O_RDWR fifo file descriptor.  This is
    currently failed by our fifo code in HEAD due to a bug in FIONREAD
    handling.  Fix to be merged shortly.

a30c1e0a0b Various and sundry improvements:
- Replace 'process' with 'thread' everywhere.
- Update several places to note that that the fact that default mutexes
  may adaptively spin isn't necessarily MD, but is just part of the
  implementation as a whole.
- Clarify the text about MTX_SPIN mutexes only being appropriate for
  INTR_FAST interrupts or other low level scheduler code to make the
  jargon more FreeBSD-ish rather than BSD/OS-ish.
- Also, note that it is possible that interrupts aren't blocked but just
  deferred when a spin lock is held (the whole blocked vs. deferred bit is
  an MD implementation detail).
- Remove statements saying that spin locks must be released in the exact
  opposite order that they were acquired.  This stopped being true several
  years ago when we first added critical sections that stored their state
  in the current thread rather than in struct mtx.
- Note that a mutex must be initialized before it is passed to any other
  mutex function, not just mtx_lock.
- Clarify that mtx_trylock() only operates on MTX_DEF mutexes.
- Simplify the text about possible preemption during a mtx_unlock().
- Use complete English sentences in place of phrases in a few places.
- Clarify that it isn't ever safe to sleep with a mutex held.  The kernel
  tends to panic when you do that.

8a22e151be As a result of kqueue locking work, socket buffer locks will always
be held when entering a kqueue filter for fifos via a socket buffer
event: as such, assert the lock unconditionally rather than acquiring
it conditionall.

db7a6c2f43 Annotate two issues:
1) fifo_kqfilter() is not actually ever used, it likely should be GC'd.

2) fifo_kqfilter_f() doesn't implement EVFILT_VNODE, so detecting events
   on the underlying vnode for a fifo no longer works (it did in 4.x).
   Likely, fifo_kqfilter_f() should forward the request to the VFS using
   fp->f_vnode, which would work once fifo_kqfilter() was detached from
   the vnode operation vector (removing the fifo override).

88f39e8e95 Introduce no-op nosup fifo kqueue filter and detach routine, which are
used when a read filter is requested on a write-only fifo descriptor, or
a write filter is requested on a read-only fifo descriptor.  This
permits the filters to be registered, but never raises the event, which
causes kqueue behavior for fifos to more closely match similar semantics
for poll and select, which permit testing for the condition even though
the condition will never be raised, and is consistent with POSIX's notion
that a fifo has identical semantics to a one-way IPC channel created
using pipe() on most operating systems.

The fifo regression test suite can now run to completion on HEAD without
errors.

456068c703 Comment test_lseek().
Add test_kqueue(), which registers and unregisters various kqueue filter
types on a fifo in order to make sure that EVFILT_READ, EVFILT_WRITE can
be registered, and that EVFILT_NETDEV can't be registered.  For now, we
don't test that EVFILT_VNODE can be registered on fifos, as that has been
broken at some point.

831a62e7e5 - Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).
- Remove an assertion in sound.c, it's not needed (and causes a panic now).
  From the conversation via mail between glebius and Ariff:
  ---snip---
  > Well, but which mutex protects now? Do we own anything else
  > in pcm_chnalloc()? I see some queue(4) macros in pcm_chnalloc(),
  > they should be protected, shouldn't they?
  Queue insertion/removal occur during
     1) driver loading (which is pretty much single thread /
        sequential) or unloading (mutex protected, bail out if there is
        any channel with refcount > 0 or busy).
     2) vchan_create()/destroy(), (which is *sigh* quite complicated), but
        somehow protected by 'master'/parent channel mutex. Other
        thread cannot add/remove vchan (or even continue traversing
        that queue) unless it can acquire parent channel mutex.

1423f2f54c Further updates to fifo_io regression test:
- Teach fifo_io about kqueue monitoring of fifo file descriptor status,
  and add test cases for kqueue to match existing case for poll and
  select.  Add a new cleanup routine, cleanfifokq(), for use in tests that
  use kqueues.  kqueue_setup() sets up kqueue sessions, and kqueue_status()
  returns file descriptor status.

- Correct a bug in select handling relating to the nfds argument, which
  was incorrect so resulted in select occuring on the wrong file descriptor,
  and possible false positive/negative results.

- Clarify error reporting in one byte write+read tests to distinguish
  errors in the after case from the before case.
