b641353e3a - Remove apause(). It makes no sense with our present mutex implementation
since simply unlocking a mutex does not ensure that one of the waiters
   will run and acquire it.  We're more likely to reacquire the mutex
   before anyone else has a chance.  It has also bit me three times now, as
   it's not safe to drop the interlock before sleeping in many cases.

58aa36f31e Checkpoint today's tidy-up of the WIP disassembler. It now agrees with
objdump --disassemble when disassembling itself in userland.  I've added
the cmovCC instruction group and tweaked a bunch of size sensitive array
indexes to either fix my mistakes and/or force it to work by any means
necessary.

I'm committing this because it is usable enough to see what is going on
when single stepping via ddb.

It might still tell lies, but its lies will be far more subtle now.  I'm
not sure that this is a good thing or not.

8ca4df3299 This is the much rumoured ATA mkIII update that I've been working on.
o       ATA is now fully newbus'd and split into modules.
        This means that on a modern system you just load "atapci and ata"
        to get the base support, and then one or more of the device
        subdrivers "atadisk atapicd atapifd atapist ataraid".
        All can be loaded/unloaded anytime, but for obvious reasons you
        dont want to unload atadisk when you have mounted filesystems.

o       The device identify part of the probe has been rewritten to fix
        the problems with odd devices the old had, and to try to remove
        so of the long delays some HW could provoke. Also probing is done
	without the need for interrupts, making earlier probing possible.

o       SATA devices can be hot inserted/removed and devices will be created/
        removed in /dev accordingly.
	NOTE: only supported on controllers that has this feature:
	Promise and Silicon Image for now.
	On other controllers the usual atacontrol detach/attach dance is
	still needed.

o	Support for "atomic" composite ATA requests used for RAID.

o       ATA RAID support has been rewritten and and now supports these
        metadata formats:
                 "Adaptec HostRAID"
                 "Highpoint V2 RocketRAID"
                 "Highpoint V3 RocketRAID"
                 "Intel MatrixRAID"
                 "Integrated Technology Express"
                 "LSILogic V2 MegaRAID"
                 "LSILogic V3 MegaRAID"
                 "Promise FastTrak"
                 "Silicon Image Medley"
		 "FreeBSD PseudoRAID"

o       Update the ioctl API to match new RAID levels etc.

o       Update atacontrol to know about the new RAID levels etc
        NOTE: you need to recompile atacontrol with the new sys/ata.h,
        make world will take care of that.
	NOTE2: that rebuild is done differently from the old system as
	the rebuild is now done piggybacked on read requests to the
	array, so atacontrol simply starts a background "dd" to rebuild
	the array.

o       The reinit code has been worked over to be much more robust.

o       The timeout code has been overhauled for races.

o	Support of new chipsets.

o       Lots of fixes for bugs found while doing the modulerization and
        reviewing the old code.

Missing or changed features from current ATA:

o       atapi-cd no longer has support for ATAPI changers. Todays its
        much cheaper and alot faster to copy those CD images to disk
        and serve them from there. Besides they dont seem to be made
        anymore, maybe for that exact reason.

o       ATA RAID can only read metadata from all the above metadata formats,
	not write all of them (Promise and Highpoint V2 so far). This means
	that arrays can be picked up from the BIOS, but they cannot be
	created from FreeBSD. There is more to it than just the missing
	write metadata support, those formats are not unique to a given
	controller like Promise and Highpoint formats, instead they exist
	for several types, and even worse, some controllers can have
	different formats and its impossible to tell which one.
	The outcome is that we cannot reliably create the metadata of those
	formats and be sure the controller BIOS will understand it.
	However write support is needed to update/fail/rebuild the arrays
	properly so it sits fairly high on the TODO list.

o       So far atapicam is not supported with these changes. When/if this
	will change is up to the maintainer of atapi-cam so go there for
	questions.

4cb39345c0 When several carp interfaces are attached to Ethernet interface,
carp_carpdev_state_locked() is called every time carp interface is attached.
The first call backs up flags of the first interface, and the second
call backs up them again, erasing correct values.
  To solve this, a carp_sc_state_locked() function is introduced. It is
called when interface is attached to parent, instead of calling
carp_carpdev_state_locked. carp_carpdev_state_locked() calls
carp_sc_state_locked() for each sc in chain.

c6ec6a7cae Eliminate (now) unnecessary acquisition and release of the global page
queues lock in vm_object_backing_scan().  Updates to the page's PG_BUSY
flag and busy field are synchronized by the containing object's lock.

Testing the page's hold_count and wire_count in vm_object_backing_scan()'s
OBSC_COLLAPSE_NOWAIT case is unnecessary.  There is no reason why the held
or wired pages cannot be migrated to the shadow object.

7ce7f713ee Eliminate v_id and v_ddid. The name cache now holds references to
vnodes whose names it caches, so we no longer need a `generation
number' to tell us if a referenced vnode is invalid.  Replace the use
of the parent's v_id in the hash function with the address of the
parent vnode.

dd33f0d92f Merge kern___cwd() and vn_fullpath(), which were virtually identical,
except for places where people forget to update one of them.  We now
collect only one set of stats for both of these routines.  Other
changes in this commit include:

- Start acquiring Giant again in vn_fullpath(), since it is required
  when crossing a mount point.

- Expand the scope of the cache lock to avoid dropping it and
  picking it up again for every pathname component.  This also
  makes it trivial to avoid races in stats collection.

- Assert that nc_dvp == v_dd for directories instead of returning
  an error to userland when this is not true.  AFAIK, it should
  always be true when v_dd is non-null.

- For vn_fullpath(), handle the first (non-directory) vnode
  separately.
