202f4add57 Various cleanups: 
- Don't initialize if_output, ether_ifattach() does this for us.
- Use pci_enable_busmaster() instead of using pci_read_config()
  and pci_write_config() directly.
- Don't try to enable I/O, bus_alloc_resource() does this for us.

801acfe1d4 - Make sigonstack() a regular function instead of an inline and add a proc 
lock assertion to it.
- SIGPENDING() no longer needs sched_lock, so only grab sched_lock to set
  the TDF_NEEDSIGCHK and TDF_ASTPENDING flags in signotify().
- Add a proc lock assertion to tdsigwakeup().
- Since we always set TDF_OLDMASK while holding the proc lock, the proc
  lock is sufficient protection to check its state in postsig() and we only
  need sched_lock when clearing the actual flag.

625dc6b51a Rather than check for M_PKTHDR and conditionally perform access control, 
simply assert that M_PKTHDR is set using M_ASSERTPKTHDR().

8b7a3b47d1 Use the proc lock to protect p_singlethread and a P_WEXIT test. This 
fixes a couple of potential KSE panics on non-i386 arch's that weren't
holding the proc lock when calling thread_exit().

f043193969 - Add a static function pgadjustjobc() to adjust the job control count for 
a process group.
- Call pgadjustjobc() twice in fixjobc() to avoid code duplication and
  improve readability.
- Use the proc lock to protect P_SHOULDSTOP() instead of sched_lock.
- Check to see if a process is PRS_NEW with sched_lock before trying to
  lock its proc lock since the lock may not be constructed yet.

691d3715d6 Backed out rev.1.57. This restores format checking functions like 
err() again.  All known err() format errors in src that developed
while format checking was broken have been fixed.  Tested on i386,
alpha, ia64.

9d51c8cfb5 Fix a bug in alpha_get_uac() that I introduced in revision 1.18. It is

not the current process.

556bb64555 - Set the ke_cpu field in sched_add() for interrupt and realtime threads 
since they are going on the current cpu and not their previously assigned
   cpu.
 - sched_runnable() should only return true in the SMP case if the other
   processor has more than one thread that is runnable.  We can not steal
   curthread.
 - Change kseq_print() to accept the cpuid instead of a kseq pointer.  This
   makes use of this function in ddb much easier.

  driver, doesn't require it anymore.

It could also be used twice in kern_thr.c but that's owned by jeff

5adc19ca85 suser() does not need the proc lock, just the setting of P_PROTECTED in

e1dd224437 - kthread's don't have p_textvp set to anything, so replace code that

5023bfe74a The sched_lock is not needed while clearing two of the P_STOPPED bits in 
p_flag.  Also, the proc lock can't be recursed, so simplify an older proc
lock assertion.

872336ea36 Don't assume that p_session hasn't changed out from under us after unlocking 
the process and session.  Instead, cache a true reference to the session
when we do the hold and release our reference on that session.  This avoids
the need for the proc lock when dropping the reference.

c94962975b fork1() already sets PS_INMEM, so don't set it again. This lets us push 
sched_lock down slightly so that it isn't needed in the RFSTOPPED case.

08b81c369f - The prison mutex cannot possibly protect pointers to the prison it

  cr_prison.

  p_ucred.

ab40c1468e - Push Giant down into the fork1() function a small bit. 
- Set p_acflag earlier while already hold the proc lock in fork1().
- Mark the realitexpire() callout MPSAFE for new processes.  It was already
  marked safe for proc0 a long while ago.
