- Make some smaller buckets for large zones to further reduce memory
waste.
- Implement uma_zone_reserve(). This holds aside a number of items only
for callers who specify M_USE_RESERVE. buckets will never be filled
from reserve allocations.

- Call lock_init() first before setting any lock_object fields in
lock init routines. This way if the machine panics due to a duplicate
init the lock's original state is preserved.
- Somewhat similarly, don't decrement td_locks and td_slocks until after
an unlock operation has completed successfully.
provided by Isilon.
- Add an rm_assert() supporting various lock assertions similar to other
locking primitives. Because rmlocks track readers the assertions are
always fully accurate unlike rw_assert() and sx_assert().
- Flesh out the lock class methods for rmlocks to support sleeping via
condvars and rm_sleep() (but only while holding write locks), rmlock
details in 'show lock' in DDB, and the lc_owner method used by
dtrace.
- Add an internal destroyed cookie so that API functions can assert
that an rmlock is not destroyed.
- Make use of rm_assert() to add various assertions to the API (e.g.
to assert locks are held when an unlock routine is called).
- Give RM_SLEEPABLE locks their own lock class and always use the
rmlock's own lock_object with WITNESS.
- Use THREAD_NO_SLEEPING() / THREAD_SLEEPING_OK() to disallow sleeping
while holding a read lock on an rmlock.

There are some systems reported, where PCI BAR(5), used for SATA registers
access, is present, but not functional. Attempt to use it brakes devices
detection logic. Try to detect those cases on attach by setting and testing
some bits in SControl register. If bits are unsettable, fallback to legacy
ATA without hot-plug detection, speed control/reporting, etc.

in FBSD 8.0, interface routes have been returened to the
applications without the RTF_GATEWAY bit. This incompatibility
has caused some issues with Zebra, Qugga and the like.
This patch provides the RTF_GATEWAY flag bit in returned interface
routes so to behave similarly to pre 8.0 systems.

checksum header. The header contains a received frame length but
the defined length for AX88772B is different with other ASIX
controllers. When the RX checksum is off, AX88772B controller does
not prepend a checksum header so driver has to use normal header
length mask.
This change should fix RX errors when RX checksum offloading is
off.

In line to what is done in UFS, define an internal type
e2fs_lbn_t for the logical block numbers.
This change is basically a no-op as the new type is unchanged
(int32_t) but it may be useful as bumping this may be required
for ext4fs.
Also, as pointed out by Bruce Evans:
-Use daddr_t for daddr in ext2_bmaparray(). This seems to
improve reliability with the reallocblks option.
- Add a cast to the fsbtodb() macro as in UFS.

- Be more explicit about zone vs keg locking. This functionally changes
almost nothing.
- Add a size parameter to uma_zcache_create() so we can size the buckets.
- Pass the zone to bucket_alloc() so it can modify allocation flags
as appropriate.
- Fix a bug in zone_alloc_bucket() where I missed an address of operator
in a failure case. (Found by pho)

mbuf that was fully consumed by the previous call, the mbuf ptr returned by the
current call ends up being the previous mbuf in the sb chain to the one that
contains the data we want.
This does not cause any observable issues because the mbuf copy routines happily
walk the mbuf chain to get to the data at the moff offset, which in this case
means they effectively skip over the mbuf returned by sbsndptr().
We can't adjust sb->sb_sndptr during the previous call for this case because the
next mbuf in the chain may not exist yet. We therefore need to detect the
condition and make the adjustment during the current call.
Fix by detecting the special case of moff being at the start of the next mbuf in
the chain and adjust the required accounting variables accordingly.

Add a phy reset capability into the stop code, this is so a static configured

This revision synchronizes the shared code with Intel internal current code,
and note that it now includes DCB supporting code, this was necessitated by
some internal changes with the code, but it also will provide the opportunity
to develop this feature in the core driver down the road.
I have edited the README to get rid of some of the worse anachronisms in it
as well, its by no means as robust as I might wish at this point however.
Oh, I also have included some conditional stuff in the code so it will be
compatible in both the 9.X and 10 environments.
Performance has been a focus in recent changes and I believe this revision
driver will perform very well in most workloads.

stops updating the vertical retrace indicator. The text mouse
renderer in syscons is executing from the callout and spins waiting
for the start of next frame. As result, after the X server finishes,
since the VGA cannot be turned on, but syscons does not know about
this, the clock swi spins forever.
Hack around the problem by disabling wait for the retrace if KMS is
activated.
