48bbf5f234 Use the queue macros from <sys/queue.h> instead of referring to the queue 
members directly.  Use *_FOREACH whenever possible.

67b2a0cf06 * Add copyin_proc() and copyout_proc(), which are like copyin() and 
copyout(), except they can operate on any process, not just curproc.
* Use this in uiomove() to allow UIO_USERSPACE to non-curproc.

f7d98e2451 - merge all the hook insertion and deletion code so that we don't create 
a fourth copy.
- add exithook to be executed when a process exits.

7380aa1467 Add a "ddb" command (if DDB is configured into the kernel) for 
easy, convenient dropping into DDB at the "root device: " prompt.
Useful if your console can't do it w/o actually taking an interrupt
and you want to, say, look at the boot messages.

PWR_SOFTRESUME. Apm calls powerhook with the values in normal interrupt

956b3ca3b3 Track which process a CPU is running/has last run on by adding a 
p_cpu member to struct proc.  Use this in certain places when
accessing scheduler state, etc.  For the single-processor case,
just initialize p_cpu in fork1() to avoid having to set it in the
low-level context switch code on platforms which will never have
multiprocessing.

While I'm here, comment a few places where there are known issues
for the SMP implementation.

a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler 
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

cd14e5fa0c Add a fifth "divisor" argument to humanize_number; suitable values are 
either 1024 or 1000.
Needed because frequencies use decimal rather than power-of-two SI
prefixes.

919df6690a Add support for / on RAID. A bit of a gross hack, but sufficient for now. 
Note that this doesn't help you much until the RAID autoconfig code
in sys/dev/raidframe/rf_netbsdkintf.c is turned on.

65c138fea0 - Print a name of root device even if it is a network device. 
- If RB_ASKNAME, only dumpdv holds the results asked interactively.
  Examie dumpspec only when !RB_ASKNAME.  This allows us to override
  dumps on none in kernel config file by booting kernel with RB_ASKNAME.
- Slightly rearrange code so that it more matches to comment.

047cc5e94f Cleanup setroot() a bit: 
- No longer necessary to use goto, just breaking the loop like other case
  is enough.
- Don't caliculate loop invariant every time.  Just reuse.

65e677bd99 Add an exec hook mechanism, where kernel subsystem can register to 
execute certain functions when a process does an exec(). Currently
uses a global list. Could possibly be done using a per-process list,
but this needs more thought.

d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference 
dev_name2blk[] directly.  Addresses PR #7622 (ITOH Yasufumi), although

719cd63d24 Implement format_bytes(), which pretty prints a given u_int64_t into a 
given buffer, and if necessary, reducing the display width of the
number to fit in the buffer by increasing the units (from kilobytes
(2^10) through to exabytes (2^60)).
