bc91c5107a o Change the implementation of vm_map locking to use exclusive locks
exclusively.  The interface still, however, distinguishes
   between a shared lock and an exclusive lock.

3fc755c118 - Protect randompid and nprocs with the allproc_lock.
- Reorder fork1() to do malloc() and other blocking operations prior to
  acquiring the needed process locks.
- The new process inherit's the credentials of curthread, not the
  credentials of the old process.
- Document a really weird race that will come up with KSE allows multiple
  kernel threads per process.

d7aadbf9ce - Reorder a few things so that when we lock the process at the end of
exit1() we don't have to release it until we acquire schd_lock to
  call cpu_throw().
- Since we can switch at any time due to preemption or a lock release
  prior to acquiring sched_lock, don't update switchtime and switchticks
  until the very end of exit1() after we have acquired sched_lock.
- Interlock the proctree_lock and proc lock in wait1() and exit1() to
  avoid lost wakeups when a parent blocks waiting for a child to exit at
  the bottom of wait1().  In exit1() the proc lock interlocked with
  proctree_lock (and released after acquiring sched_lock) is that of
  the parent process.
- In wait1() use an exclusive lock of proctree lock while we are
  looking for a process to harvest.  This allows us to completely
  remove all references to the process once we've found one (i.e.,
  disconnect it from pgrp's, session's, zombproc list, and it's parent's
  children list) "atomically" without needing to worry about a lock
  upgrade.
- We don't need sched_lock to test if p_stat is SZOMB or SSTOP when holding
  the proc lock since the proc lock is always held with p_stat is set to
  SZOMB or SSTOP.
- Protect nprocs with an xlock of the allproc_lock.

9b3b1c5fdf - Reorder execve() so that it performs blocking operations before it
locks the process.
- Defer other blocking operations such as vrele()'s until after we
  release locks.
- execsigs() now requires the proc lock to be held when it is called
  rather than locking the process internally.

b9ba893179 Move around the dbg code a bit so it's always under a lock. This stops a

2647924585 - Replaced the Atm_connection storage pool with an uma_zone of
Atm_connection items.
- Replaced the Atm_connvc storage pool with an uma_zone of Atm_connvc
  items.
- Created void atm_cm_init(void *) and added it to the netatm init code.
  I'm thinking that there will definetly be more ``subsystem'' init
  functions to be added so I'll probably change these calls to be a for
  loop through init routines (or something).

5a34a9f089 malloc/free(9) no longer require Giant. Use the malloc_mtx to protect the
mallochash.  Mallochash is going to go away as soon as I introduce the
kfree/kmalloc api and partially overhaul the malloc wrapper.  This can't happen
until all users of the malloc api that expect memory to be aligned on the size
of the allocation are fixed.

same on Alpha and lint(1) pointed that out.

lint(1) on the same architecture pointed out how silly a cast to (u_int) to
malloc(3)'s argument was.  Change that to size_t.

48988cd4bd xdm plays horrid tricks with PAM, and dumps core if it's allowed to call
pam_lastlog, so add a dummy session chain to avoid using the one from
pam.d/other.  I assume gdm does something similar, so give it a dummy
session chain as well.

b50a72861d Make -J a proper flag internal to the code (rather than just check for

Some people happen to think it's idiotic to limit to 5 arguments, so
let the user override it if they like.

639c9550fb Remove the temporary alignment check in free().
Implement the following checks on freed memory in the bucket path:
	- Slab membership
	- Alignment
	- Duplicate free

This previously was only done if we skipped the buckets.  This code will slow
down INVARIANTS a bit, but it is smp safe.  The checks were moved out of the
normal path and into hooks supplied in uma_dbg.

0fa5e8dc42 Rework some of the -I support so I can't find a way to make xargs(1) core or
corrupt memory.  Simplifies the code in one or two places, also removes some
code that looks like it was bogus or incomplete.

Update strnsubst to have one or two extra conditions which maybe would make
it more efficient, or at least more versatile.  This is likely a no-op.

f77e6d9569 If we get a DATA UNDERRUN error from QLogic FC cards, but the RQCS_RU bit
is not set in the scsi completion status, or if the residual is clearly
nonsense, then this was a command that suffered the loss of one or more
