02e878d97c - 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.

f029471dbe 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.

05f44fb980 Revert parts of 1.309 to allow processes to have a signal mask 
independently from the threads again.
Will be adding code to use this soon..

424da6cb60 Fix a bug in alpha_get_uac() that I introduced in revision 1.18. It is 
supposed to return the uac of the parent process of the current process,
not the current process.

Not doing this caused the vlan mtu to be reduced by 4 bytes.

b37d8ead52 Don't grab Giant in slab_zalloc() if M_NOWAIT is specified. This 
should allow the use of INTR_MPSAFE network drivers.

7cd650a972 - 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.

1e1e003218 - Convert NetBSD-derived macros to inline functions for better 
type-checking and future debug code.
- Remove sparse addressing hack, since the only consumer, the macio ATA
  driver, doesn't require it anymore.

d3a0bd78a8 Add a thread_unlink() and use it. 
It could also be used twice in kern_thr.c but that's owned by jeff
so I'l let him change it when he's next there.

69297bf8c9 suser() does not need the proc lock, just the setting of P_PROTECTED in 
p_flag needs the lock.

cd4ed3b5b0 - kthread's don't have p_textvp set to anything, so replace code that 
dealt with that possibility with a KASSERT().
- No need to set P_SYSTEM, kthread_create() does that for us.

213b19e9fb - Use a local struct proc variable to improve readability. 
- Use a local variable to close a minor race when determining if the wmesg
    printed out needs a prefix such as when a thread is blocked on a lock.

b68e08498f 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.

b5a2bad175 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.

0bfc4d1445 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.

69c4ee54ff - The prison mutex cannot possibly protect pointers to the prison it 
protects, so don't bother locking it while we assign it to a ucred's
  cr_prison.
- Fully construct the new credential for a process before assigning it to
  p_ucred.

bb0e8070fd - 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.

f36403612a - Use a local variable to close a minor race when determining if the wmesg

  td_wchan members of struct thread.

418e9d1b9e P_SHOULDSTOP used to be p_stat == SSTOP and needed the sched_lock, now it 
is protected by the proc lock and doesnt' need sched_lock, so adjust the
locking appropriately.
