1948 zpool list should show more detailed pool information
Display per-vdev information with "zpool list -v".
The added expandsize property has currently no value on FreeBSD.
This changeset allows adding expansion support to individual vdevs
in the future.

Revert r115805. An array type is required to have a range type,
however, the range can be unknown for the upper bound.
Testcase to follow.
Part of rdar://11457152
This should fix ctfconvert producing error messages during kernel
builds, similar to:
ERROR: scsi_all.c: die 24561: failed to retrieve array bounds
These were caused by incorrect debug information for flexible array
members of structs.

implementation specific vs. the common architecture definition.
Bring PPC4XX defines (PSL, SPR, TLB). Note the new definitions under
BOOKE_PPC4XX are not used in the code yet.
This change set is not supposed to affect existing E500 support, it's just
another reorg step before bringing support for E500mc, E5500 and PPC465.

Prior to this, setting VersionAddendum will be a no-op: one will
always have BASE_VERSION + " " + VERSION_HPN for VersionAddendum
set in the config and a bare BASE_VERSION + VERSION_HPN when there
is no VersionAddendum is set.
HPN patch requires both parties to have the "hpn" inside their
advertized versions, so we add VERSION_HPN to the VERSION_BASE
if HPN is enabled and omitting it if HPN is disabled.
VersionAddendum now uses the following logics:
* unset (default value): append " " and VERSION_ADDENDUM;
* VersionAddendum is set and isn't empty: append " "
and VersionAddendum;
* VersionAddendum is set and empty: don't append anything.

are handled in most CAM peripheral drivers that are not handled by
GEOM's disk class.
The usual character driver open and close semantics are that the
driver gets N open calls, but only one close, when the last caller
closes the device.
CAM peripheral drivers expect that behavior to be honored to the
letter, and the CAM peripheral driver code (specifically
cam_periph_release_locked_busses()) panics if it is done incorrectly.
Since devfs has to drop its locks while it calls a driver's close
routine, and it does not have a way to delay or prevent open calls
while it is calling the close routine, there is a race.
The sequence of events, simplified a bit, is:
- devfs acquires a lock
- devfs checks the reference count, and if it is 1, continues to close.
- devfs releases the lock
- 2nd process open call on the device happens here
- devfs calls the driver's close routine
- devfs acquires a lock
- devfs decrements the reference count
- devfs releases the lock
- 2nd process close call on the device happens here
At the second close, we get a panic in
cam_periph_release_locked_busses(), complaining that peripheral
has been released when the reference count is already 0. This is
because we have gotten two closes in a row, which should not
happen.
The fix is to add the D_TRACKCLOSE flag to the driver's cdevsw, so
that we get a close() call for each open(). That does happen
reliably, so we can make sure that our reference counts are
correct.
Note that the sa(4) and pt(4) drivers only allow one context
through the open routine. So these drivers aren't exposed to the
same race condition.
scsi_ch.c,
scsi_enc.c,
scsi_enc_internal.h,
scsi_pass.c,
scsi_sg.c:
For these drivers, change the open() routine to
increment the reference count for every open, and
just decrement the reference count in the close.
Call cam_periph_release_locked() in some scenarios
to avoid additional lock and unlock calls.
scsi_pt.c: Call cam_periph_release_locked() in some scenarios

- Move the variables of sym_action2() out of nested scope as required
by style(9) and remove extraneous curly braces.
- Replace a magic value for PCIR_COMMAND with the appropriate macro.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.

longer uses the active and inactive paging queues. Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.
Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero. However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed. The new
pmap_pv_reclaim() doesn't even try.
