- Use pci_get_powerstate()/pci_set_powerstate() in all the other drivers
that need them so we don't have to fiddle with the PCI power management
registers directly.
- Use pci_enable_busmaster()/pci_enable_io() to turn on busmastering and
PIO/memory mapped accesses.
- Add support to the RealTek driver for the D-Link DFE-530TX+ which has
a RealTek 8139 with its own PCI ID. (Submitted by Jason Wright)
- Have the SiS 900/National DP83815 driver be sure to disable PME
mode in sis_reset(). This apparently fixes a problem on some
motherboards where the DP83815 chip fails to receive packets.

Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
Set the user and goal settings prior to setting the current
settings. This allows the async update routine to filter out
intermediate transfer negotiation updates that may be less
than interesting. The Linux OSM uses this to reduce the amount
of stuff printed to the console.
aic7xxx.seq:
Correct an issue with the aic7770 in twin channel mode.
We could continually attempt to start a selection even
though a selection was already occurring on one channel.
This might have the side effect of hanging our selection
or causing us to select the wrong device.
While here, create a separate polling loop for when we
have already started a selection. This should reduce
the latency of our response to a (re)selection. The diffs
look larger than they really are due to some code rearrangement
to optimize out a jmp.
aic7xxx_freebsd.c:
Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
aic7xxx_inline.h:
Get back in sync with perforce revision ID.
aic7xxx_pci.c:
Identify adapters in ARO mode as such.
Ensure that not only the subvendor ID is correct (9005)
but also that the controller type field is valid before
looking at other information in the subdevice id. Intel
seems to have decided that their subdevice id of 8086
is more appropriate for some of their MBs with aic7xxx
parts than Adaptec's sanctioned scheme.
Add an exclusion entry for SISL (AAC on MB based adapters).
Adapters in SISL mode are owned by the RAID controller, so
even if a driver for the RAID controller is not present,
it isn't safe for us to touch them.
if (error = function(a1, a2))

credential structure, ucred (cr->cr_prison).
o Allow jail inheritence to be a function of credential inheritence.
o Abstract prison structure reference counting behind pr_hold() and
pr_free(), invoked by the similarly named credential reference
management functions, removing this code from per-ABI fork/exit code.
o Modify various jail() functions to use struct ucred arguments instead
of struct proc arguments.
o Introduce jailed() function to determine if a credential is jailed,
rather than directly checking pointers all over the place.
o Convert PRISON_CHECK() macro to prison_check() function.
o Move jail() function prototypes to jail.h.
o Emulate the P_JAILED flag in fill_kinfo_proc() and no longer set the
flag in the process flags field itself.
o Eliminate that "const" qualifier from suser/p_can/etc to reflect
mutex use.
Notes:
o Some further cleanup of the linux/jail code is still required.
o It's now possible to consider resolving some of the process vs
credential based permission checking confusion in the socket code.
o Mutex protection of struct prison is still not present, and is
required to protect the reference count plus some fields in the
structure.

treat 0 as a wildcard in src/sys/in_pbc.c:in_pcbnotify()
It's sufficient to check for src|local port, as we'll have no

Without this a attacker sending ICMP messages, where the attached
IP header (+ 8 bytes) has the address and port numbers == 0, would
have the ICMP message applied to all sessions.

Simplify (hopefully) it by moving all error returns closer to
the beginning of the function.
Return an error when "Error removing subdisk %s: not found in

after printing that error message.
Adding make_dev() and destroy_dev() calls in (hopefully) the right
places.
This is done by calling make_dev() in each object constructor and
caching the dev_t's returned from make_dev() in each struct
'subdisk'(sd), 'plex' and 'volume' such that the 'object'_free()
functioncs can call destroy dev.
This change makes a subset of the old /dev/vinum appear under devfs.
Enough nodes appear such that I'm able to mount my striped volume.
There may be more work needed to get vinum configuration working
properly.
that was introduced in revision 1.80. The problem manifested
itself with a `locking against myself' panic and could also
result in soft updates inconsistences associated with inodedeps.
The two problems are:
1) One of the background operations could manipulate the bitmap
while holding it locked with intent to create. This held lock
results in a `locking against myself' panic, when the background
processing that we have been coopted to do tries to lock the bitmap
which we are already holding locked. To understand how to fix this
problem, first, observe that we can do the background cleanups in
inodedep_lookup only when allocating inodedeps (DEPALLOC is set in
the call to inodedep_lookup). Second observe that calls to
inodedep_lookup with DEPALLOC set can only happen from the following
calls into the softdep code:
softdep_setup_inomapdep
softdep_setup_allocdirect
softdep_setup_remove
softdep_setup_freeblocks
softdep_setup_directory_change
softdep_setup_directory_add
softdep_change_linkcnt
Only the first two of these can come from ffs_alloc.c while holding
a bitmap locked. Thus, inodedep_lookup must not go off to do
request_cleanups when being called from these functions. This change
adds a flag, NODELAY, that can be passed to inodedep_lookup to let
it know that it should not do background processing in those cases.
2) The return value from request_cleanup when helping out with the
cleanup was 0 instead of 1. This meant that despite the fact that
we may have slept while doing the cleanups, the code did not recheck
for the appearance of an inodedep (e.g., goto top in inodedep_lookup).
This lead to the softdep inconsistency in which we ended up with
two inodedep's for the same inode.
