df970488b3 Move the 'debug' sysctl tree under options SYSCTL_DEBUG. It generates
an inordinate amount of synchronous console output that is fairly
undesirable on slower serial console.  It's easily hit by accident
when frobbing other sysctls late at night.

d6dd4af4ac Forcibly disable interrupts, if we find ourselves servicing one when
the device is suspended or shutting down. This will need to be rethought
slightly if we implement suspend/resume support within vr(4).
This appears to fix the vr_shutdown() panic on SMP machines.

My theory here is there's a race somewhere during vr_detach() with
vr_intr() in the SMP case which was sometimes being triggered,
although quite why this was happening is unclear (vr_stop() also
explicitly disables interrupts by writing to the IMR register).

MFC-to-RELENG_5* candidate.

b08abf6cc0 During traversal of the active queue, try locking the page's containing
object before accessing the page's flags or the object's reference count.
If the trylock fails, handle the page as though it is busy.

3904b13fab Raise MAXDSIZ from 8G to 32G. The old limit was just an arbitary choice
that was greater than 4G.  I originally used the same values as i386 in
order to save opening a new PML4 page slot, but in the day of gigabytes
of memory, worrying about a 4K page seems futile.  Moving from 8 to 32G
moves the page to a different index, it doesn't increase the number of
pages used.

66e1a311f5 Fix brk(3). The stack was unbalanced when we jumped to cerror. Oops!
This causes nasty things like SEGV or a cpu spin when we return.

This is not quite a perfect separation: the syncer still think it knows

6e77a04170 The island council met and voted buf_prewrite() home.
Give ffs it's own bufobj->bo_ops vector and create a private strategy
routine, (currently misnamed for forwards compatibility), which is
just a copy of the generic bufstrategy routine except we call
softdep_disk_prewrite() directly instead of through the buf_prewrite()
indirection.

Teach UFS about the need for softdep_disk_prewrite() and call the
function directly in FFS.

Remove buf_prewrite() from the default bufstrategy() and from the
global bio_ops method vector.

5d9d81e7ea Put the I/O block size in bufobj->bo_bsize.
We keep si_bsize_phys around for now as that is the simplest way to pull
the number out of disk device drivers in devfs_open().  The correct solution
would be to do an ioctl(DIOCGSECTORSIZE), but the point is probably mooth
when filesystems sit on GEOM, so don't bother for now.

fae974f156 Degeneralize the per cdev copyonwrite callback. The only possible value
is ffs_copyonwrite() and the only place it can be called from is FFS which
would never want to call another filesystems copyonwrite method, should one
exist, so there is no reason why anything generic should know about this.

7a7386a3e2 Device driver for onboard CS4231 audio controller which is found
on UltraSPARC workstations. The driver is based on OpenBSD's SBus
cs4231 driver and heavily modified to incorporate into sound(4)
infrastructure. Due to the lack of APCDMA documentation, the DMA
code of SBus cs4231 came from OpenBSD's driver.
The driver runs without Giant lock and supports both SBus and EBus
based CS4231 audio controller. Special thanks to marius for providing
feedbacks during the driver writing. His feedback made it possible
to write hiccup free playback code under high system loads.
