- Remove the old gcc <= 2.8 versions of the atomic ops.
- Resort the order of some things in the file so that there is only

- Remove ATOMIC_ACQ_REL() and just use explicit macros instead.

In other changes: Add in a SA_QUIRK_NO_CPAGE quirk so that it's possible
to avoid using a (broken) device's implementation of he DEVICE COMPRESSION

Also do a couple of printout cleanups.
As per some discussion on FreeBSD-scsi, skip doing tape flushing
if we're reading tape logical block location (MTIOCRDSPOS).
(so we can see rapidly whether something was a fabric device but is
now gone).
Add a tag which says what role this adapter should take. It can take
on the value of None, Target, Initiator or Both. None is useful for
warm failover purposes. Remove the ISP_CFG_NOINIT silliness since
a role of "None" does this.
Add a isp_lastmbxcmd tag to store the opcode for the last mailbox
command used.
Module) and FBM (Fibre Buffer Modules). Also remember to clear the
semaphore registers. Tell the RISC processor to not halt on FPM
parity errors.
Throw out the ISP_CFG_NOINIT silliness and instead go to the use of
adapter 'roles' to see whether one completes initialization or not
(mostly for Fibre Channel). The ultimate intent, btw, of all of this
is to have a warm standby adapter for failover reasons. Because
we do roles now, setting of Target Capable Class 3 service parameters
in the ICB for the 2x00 cards reflects from role. Also, in isp_start,
if we're not supporting an initiator role, we bounce outgoing commands
with a Selection Timeout error. Also clean out the TOGGLE_TMODE
goop for FC- there is no toggling of target mode like there is
for parallel SCSI cards.
Do more cleanup with respect to using target ids 0..125 in F-port
topologies. Also keep track of things which *were* fabric devices
so that when you rescan the fabric you can notify the outer layers
when fabric devices go away.
Only force a LOGOUT for fabric devices if they're still logged in
(i.e., you cat their Port Database entry. Clean up the Get All Next

Finally, use a new tag in the softc to store the opcode for the
last mailbox command used so we can report which opcode timed
out.
in-core pointers to summary information. An array in this region
(fs_csp) could overflow on filesystems with a very large number of
cylinder groups (~16000 on i386 with 8k blocks). When this happens,
other fields in the superblock get corrupted, and fsck refuses to
check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs'
with a single pointer, and add padding to keep the length of the
128-byte region fixed. Update the kernel and userland utilities
to use just this single pointer.
With this change, the kernel no longer makes use of the superblock
fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c
to indicate that these fields must be calculated for compatibility
with older kernels.

have spoken with quite a few folks about this and the support for doing
this was pretty strong. I dont remember names though, so I cannot share
the blame :-(. Note that this does not *remove* DD mode, it just stops
waving it at new users. You can still set it via config files etc, and
the bootblocks and kernel still support it. You can still use disklabel
to make true DD disks.
time I tinkered around here. Since INTREN is called from the interrupt
critical path now, it should not be too expensive. In this case, we
look at the bits being changed to decide which 8 bit IO port to write to
rather than unconditionally writing to both. I could probably have gone
further and only done the write if the bits actually changed, but that
seemed overkill for the usual case in interrupt threads.

setting kern.random.sys.seeded to 0(OFF) will cause /dev/random

will be changed back to 1(ON).
While I'm here, clean up the sysctls, and make them dynamic.
