7ce26133ea Force FWRITE on when opening the console, so that the flags passed to 
vn_close match those from vn_open.  This fixes the panic some people
were seeing about "vrele: missed vn_close".

(make struct {proc,thread,kse,ksgrp} readable again.)

882bcf5879 Document the requirements and nature of the logical CPU IDs. It isn't 
very strict and leaves much up to the platform so that it can define a
convenient mapping.

ee1fbec1bf Change the module name from 'snd_cmipci' to 'snd_cmi' to match the 
filename, module name in the loader, the dependency in snd_driver.ko, and
to be consistent with other sound drivers.

04c2a8f6be * Clear the TLB on boot. 
* If a pte for a location given to pmap_enter_quick is valid, just give
  up - don't panic, even if the mapping is different.

45740e15b4 If we get an unhandled page fault in kernel mode, either panic (if 
pcb_onfault is not set) or arrange to restart at the location in
pcb_onfault.

This ought to help the stability of a system under moderate load. It
certainly stops DDB from hanging the kernel when it tries to access a
non-present page.

c5ca5a55a1 - Clean up the comments slightly here to make them more readable. 
- Set the type and trapframe number for the F00F workaround since type
  can be used later by sv_transtrap().  Debuggers might also want to look
  at the type in the trapframe.

c1787d3b75 o Note an additional potential problem here: LOCKD_MSG directly exports 
struct ucred to userland.  In 5.0-CURRENT, it is desirable to instead
  export struct xucred, as ucred contains mutexes, pointers, and other
  kernel evil.  I'll add it to my work queue.

fc16d270b7 Tra-La, another QLogic f/w funny- this time with the 2300. 
If we get a completion status of RQCS_QUEUE_FULL, it means
that the internal queues are full. Other QLogic boards set
the QFULL SCSI status. But *nooooooooooo*, not the 2300.

21cbf0cc8b - Change getenv_quad() to return an int instead of a quad_t since it

b5c05ddcb8 o Add two comments identifying problems with the current nfs_lock.c 
implementation, so that the information doesn't get lost.
  (1) /var/run/lock is looked up relative to the current thread's root
      directory, but it's not clear that's desirable.
  (2) A race condition associated with live credential modification on
      a shared credential is present when privilege is granted for
      the purposes of talking to /var/run/lock.

fc2749a40c o vn_open() fails to call VOP_CLOSE() if vfs_object_create fails. Ideally 
all successful calls to VOP_OPEN() might be reflected in a call to
  VOP_CLOSE().  For now, simply add a comment reflecting this problem;
  this should be fixed at some point.

2ce87d3448 Break out the bus front ends into their own files. Rewrite 
sio_pccard_detach to use new siodetach.  Add an extra arg to sioprobe
to tell driver to probe/not probe the device for IRQs.

This incorporates most of Bruce's review material.  I'm at a good
checkpoint, but there will be more to come based on bde's further
reviews.
