8d9888d37a Don't wait forever for CPUs to stop or restart. Instead, give up after a
timeout.  If DIAGNOSTIC is turned on, then display a message to the console
with a map of which CPUs failed to stop or restart.  This gives an SMP box
at least a fighting chance of getting into DDB if one of the other CPUs has
interrupts disabled.

df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

5855006767 Add a consistent API to a feature that most modern CPUs have; a fast
counter register in-CPU.

This is to be used as a fast "timer", where linearity is more important
than time, and multiple lines in the linearity caused by multiple CPUs
in an SMP machine is not a problem.

This adds no code whatsoever to the FreeBSD kernel until it is actually
used, and then as a single-instruction inline routine (except for the
80386 and 80486 where it is some more inline code around nanotime(9).

fa2fbc3dac - Protect the callout wheel with a separate spin mutex, callout_lock.
- Use the mutex in hardclock to ensure no races between it and
  softclock.
- Make softclock be INTR_MPSAFE and provide a flag,
  CALLOUT_MPSAFE, which specifies that a callout handler does not
  need giant.  There is still no way to set this flag when

2c4ab9ddfa Make linux_sendsig and linux_sigreturn use all 64 bits of a
linux_sigset_t by updating the linux_sigframe struct so as to include
linux's "extramask" field.  This field contains the upper 32-bits of
the sigset.  extramask sits behind a linux_fpstate struct, which I've
defined primarily for padding purposes.

While we're here, define LINUX_NSIG in terms of LINUX_NBPW (32) and
LINUX_NSIG_WORDS (2).

This fixes problems where threaded apps would accumulate a large
number of zombies.  This was happening because the exit signal resides
in the upper 32-bits of the sigset and was never getting unmasked by
the manager thread after the first child exited.

sysentvec as to properly take the size of the machine- and
ABI dependent struct sigframe into account.

8192 to preserve behavior. The real values (if different) are
not known at this time. Other ABI modules use the real
values.

6b1d8ceabe Fix CMSG and ALIGN macro usage.
Previously we had to include <machine/param.h> or <sys/param.h> bogusly
due to the fact that <sys/socket.h> CMSG macros needed the ALIGN macro,
which was defined in param.h.  However, including param.h was a disaster
for namespace pollution.
This solution, as contributed by shin a while ago, fixes it elegantly
by wrapping the definitions around some namespace pollution preventer
definitions.
This patch was long overdue.
This should allow any network programmer to use <sys/socket.h> as
before.
