9a44fd008d Remove the global cdev hash and use the cdevsw list instead.
Don't remove the now unused element from cdev yet, wait until
we have a better reason to bump the version.

There is now no longer any upper limit on how many device drivers
a FreeBSD kernel can have.

4a949bda2b - Set cn_lkflags to LK_SHARED in the LOOKUP_SHARED case so that we only
acquire shared locks on intermediate directories.
 - For the LASTCN, we may have to LK_UPGRADE the parent directory before
   we lookup the last component.
 - Acquire VFS_ROOT and dp locks based on the cn_lkflag.

b82462f008 - Dont clear OWEINACT in vbusy(), we still owe an inactive call if someone
vhold()s us.
 - Avoid an extra mutex acquire and release in the common case of vgonel()
   by checking for OWEINACT at the start of the function.
 - Fix the case where we set OWEINACT in vput().  LK_EXCLUPGRADE drops our
   shared lock if it fails.

3e1273271d More additions for amd64:
- On amd64, InterlockedPushEntrySList() and InterlockedPopEntrySList()
  are mapped to ExpInterlockedPushEntrySList and
  ExpInterlockedPopEntrySList() via macros (which do the same thing).
  Add IMPORT_FUNC_MAP()s for these.

- Implement ExQueryDepthSList().

b1238bf60e Fix another amd64 issue with lookaside lists: we initialize the
alloc and free routine pointers in the lookaside list with pointers
to ExAllocatePoolWithTag() and ExFreePool() (in the case where the
driver does not provide its own alloc and free routines). For amd64,
this is wrong: we have to use pointers to the wrapped versions of these
functions, not the originals.

12c3eeb4fa Tweak to hopefully make lookaside lists work on amd64: in Windows, the
nll_obsoletelock field in the lookaside list structure is only defined
for the i386 arch. For amd64, the field is gone, and different list
update routines are used which do their locking internally. Apparently
the Inprocomm amd64 driver uses lookaside lists. I'm not positive this
will make it work yet since I don't have an Inprocomm NIC to test, but
this needs to be fixed anyway.

fc3b18bce3 Correct a pair of buffer overflows in the telnet(1) command:
(CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
 functions.

 (CAN-2005-0469) A global uninitialized data section buffer overflow in
 slc_add_reply() and related functions.

As a result of these vulnerabilities, it may be possible for a malicious
telnet server or active network attacker to cause telnet(1) to execute
arbitrary code with the privileges of the user running it.

a5324b331d - Remove an unused variable from relookup().
- Assert that REMOVE, CREATE, and RENAME callers have WANTPARENT
   or LOCKPARENT set.  You can't complete any of these operations without
   at least a reference to the parent.  Many filesystems check for this case
   even though it isn't possible in the current system.

   set and another thread was locking the other way up the tree.
