389fb0b432 o acknowledge interrupts early in the interrupt handler
o stop processing interrupts after a firmware fatal error or a radio kill
o clarify the possible values for the 'antenna' sysctl.
o by default, let the firmware do antenna diversity.
  the  firmware will periodically switch to another antenna to evaluate the
  signal quality.

8e8f0765ab Flip the switch and don't route interrupts to hyperthreads in a HT system.
In at least one benchmark this showed around a 20% performance increase.
If other workloads do benefit from having hyperthreads service interrupts,
we can always make this a loader tunable.

10dbb44a9f The pf' and pflog' sources do not depend on DEV_PF or DEV_PFLOG,
which is normal for own files of a device driver.

DEV_FOO should be used if an unrelated kernel file needs to know of
the `foo' driver's static presence.  Obviously, module source files
should never use DEV_*.

0f038c05ea Add slop to "backwards" cpu accounting messages, 3 usec or 1% whichever
triggers.

This should eliminate all the trivial messages which result from minor
increases in cpu_tick frequency.

Machines which don't du cpu clock fiddling shouldn't issue "backwards"
messages now.

Laptops and other machines where the initial estimate of cputicks may be
waaaay off will still issue warnings.

791dd2fade Use vn_start_secondary_write() and vn_finished_secondary_write() as a
replacement for vn_write_suspend_wait() to better account for secondary write
processing.

Close race where secondary writes could be started after ffs_sync() returned
but before the file system was marked as suspended.

Detect if secondary writes or softdep processing occurred during vnode sync
loop in ffs_sync() and retry the loop if needed.

fb46e061e4 When parsing an RPC request in nfsrv_dorec(), KASSERT that there
actually is an mbuf to process.  This catches the missing mbuf before it
would otherwise causes a NULL pointer dereference, which could be
triggered by a 0 length RPC record before the check for such records was
added in rev 1.97.

9f5349f23d Fix a bug in NFSv3 READDIRPLUS reply processing
The client's READDIRPLUS logic skips the attributes and
filehandle of the ".." entry.  If the server doesn't send
attributes but does send a filehandle for "..", the
client's logic doesn't account for the extra "value
follows" field that indicates whether the filehandle is
present, causing the remaining entries in the reply
to be ignored.

e1e31c0e43 Clean up the way we handle auxiliary commands for a given ddb command
table.  Previously, the ddb code knew of each linker set of auxiliary
commands and which explicit command list they were tied to.  These changes
add a simple command_table struct that contains both the static list of
commands and the pointers for any auxiliary linker set of additional
commands.  This also makes it possible for other arbitrary command tables
to be defined in other parts of the kernel w/o having to edit ddb itself.

The DB_SET macro has also been trimmed down to just creating an entry in
a linker set.  A new DB_FUNC macro does what the old DB_SET did which is
to not only add an entry to the linker set but also to include a function
prototype for the function being added.  With these changes, it's now also
possible to create aliases for ddb functions using DB_SET() directly if
desired.

0499f1d8a7 Use the Alpha PCC as a cpu ticker for process runtime accounting. This is
slightly more tricky than on x86 as although the PCC is 64-bits, it is not
a simple 64-bit counter like the TSC.  Instead, the upper 32-bits have
PAL-defined behavior and the lower 32-bits run as a free-running 32-bit
counter.  To handle this, we detect overflows by maintaining a small amount
of per-cpu state and use this to simulate the upper 32-bits of the counter
providing a full 64-bit counter to the consumers of cpu_ticks().

28c2f17ccb - Simplify the i8254 timecounter for the alpha since we don't actually have
an interrupt handler for the i8254.  (Our clock interrupts come from
  elsewhere.)  Instead, use the same algo that i386 uses when the lapic
  timer is in use.  This lets us remove a lot of cruft that tried to handle
  the i8254 interrupts that we weren't even using or setting up a handler
  for.
- G/C a bunch of unused cruft while I'm here.
- Fix the code to not use the rpcc timecounter (similar to TSC) on SMP
  machines to only disable that timecounter if more than one CPU is in
  use by the kernel.  Previously, a UP kernel on a machine with multiple
  CPUs would needlessly disable this timecounter.

67c0796ca3 For consistency sake, use >= MINCLSIZE rather than > MINCLSIZE to determine
whether or not to allocate a full mbuf cluster rather than just a plain
mbuf when adding on additional mbufs in m_getm().  In practice, there wasn't
any resulting mem trashing since m_getm() doesn't ever allocate an mbuf with
a packet header, and MINCLSIZE is the available payload in an mbuf with a
header rather than the available payload in a plain mbuf.
