0385d64761 r_spare1 and r_spare2 aren't needed. They aren't used. They can't be
accessed from outside of subr_rman.c.  Remove them.

and watching a debounce followed by a timeout, I think
I'm forced to conclude that it was not a good idea.

fea3efe5bf Implement rw_try_upgrade() and rw_downgrade(). rw_try_upgrade() makes a
single attempt at upgrading a read lock to a write lock, and rw_downgrade()
converts curthread's write lock into a read lock.

ae78672c56 MFp4 (checkpoint of work in progress):
o Use a directory layout that is more akin to the i386 boot layout.
o Create a libat91 for library routines that are used by one or more
  of the boot loaders.
o Create bootiic for booting from an iic part.
o Create bootspi for booting from an spi part.
o Optimize the size of many of these routines (especially emac.c).  Except
  for the emac.c optimizations, all these have been tested.
o eliminate the inc directory, libat91 superceeds it.
o Move linker.cfg up a layer to allow it to be shared.

2901a7b7d4 In receiving a new ATIO, don't record the associated CCB in the target
state structure. This field is only for CCBs that are associated with
actions that are occurring on the HBA (i.e., XPT_CONT_IO actions).

This way we also don't get confused when the upstream listener stalls
try and look at a CCB which has already been freed (by CAM).

714d4fe9b6 If we're doing a try-alloc of a pv entry and give up early, do not forget
to reduce the pv_entry_count counter.  This was found by Tor Egge.  In the
same email, Tor also pointed out the pv_stats problem in the previous
commit, but I'd forgotten about it until I went looking for this email
about this allocation problem.

efa86db61d Adaptively spin before blocking on the turnstile if an rwlock is write
locked.  In general the adaptive spinning is similar to the same code
for mutexes with some extra trickiness in rw_wunlock_hard().  Specifically,
even though both wait bits might be set and we might have a turnstile with
at least one waiting thread, there might not be any threads blocked on the
queue we are not waking up (they might all be spinning), and we should
only preserve the waiting flag for the queue we aren't waking up if there
are in fact threads blocked on that queue.  Secondly, there might not be
any threads blocked on the queue we have chosen to waken threads from
(there might only be threads blocked on the other queue and the threads
for this queue are all spinning) in which case we disown the turnstile
instead of doing a braodcast and unpend.

queue on a turnstile is empty.
- Add a turnstile_disown() function that allows a thread to give up

c082905bb6 Fix storing offset of already synchronized data. Offset in entire array was
stored in metadata instead of an offset in single disk.
After reboot/crash synchronization process started from a wrong offset
skipping (not synchronizing) part of the component which can lead to data
corrutpion (when synchronization process was interrupted on initial
synchronization) or other strange situations like 'graid3 status' showing
value more than 100%.

38bf165fa1 - Add a rw_wowner() macro that just returns the owner of a write lock and
use it in places that only care about the write owner instead of
  rw_owner() as a baby step towards limited read-lock owner.
- Tidy the code that sets the WAITER flag bits to not duplicate a test
  around the atomic operation and the KTR trace in both of the lock
  functions.
