drm/radeon: force dma32 to fix regression rs4xx,rs6xx,rs740

drm/radeon: initialize tracked CS state
drm/radeon: fix reading CB_COLORn_MASK from the CS
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug]
This causes the pipe to be forced off prior to initial mode set, which
roughly mirrors the behavior of the i915 driver. It fixes initial mode
setting on my Intel DN2800MT (Cedarview) board. Without it, mode
setting triggers an out-of-range error from the monitor for most modes,
but only on initial configuration (i.e. they can be configured
successfully from userspace after that).

by reenabling IRQ before calling ->poll, but it seems more
problems are introduced after that patch:
http://ozlabs.org/~akpm/stuff/IMG_20120824_122054.jpghttp://marc.info/?l=linux-netdev&m=134563282530588&w=2
So it is safe to fix be2net driver code directly.
This patch reverts the offending commit and fixes be_poll() by
avoid disabling BH there, this is okay because be_poll()
can be called either by poll_napi() which already disables
IRQ, or by net_rx_action() which already disables BH.

"I've split out the big send/receive update from my last pull request
and now have just the fixes in my for-linus branch. The send/recv
branch will wander over to linux-next shortly though.
The largest patches in this pull are Josef's patches to fix DIO
locking problems and his patch to fix a crash during balance. They
are both well tested.
The rest are smaller fixes that we've had queued. The last rc came
out while I was hacking new and exciting ways to recover from a
misplaced rm -rf on my dev box, so these missed rc3."

radeon_ring_restore is freeing the memory for the saved
ring data. We need to remember that, otherwise we try to
restore the ring data again on the next try. Additional
to that it shouldn't try the reset infinitely if we have

Adjust the panel mode setup to match the behavior
of the vbios. Rather than checking for specific
bridge chip ids, just check the eDP configuration register.
This saves extra aux transactions and works across
DP bridge chips without requiring additional per chip
id checking.

Power gating is per crtc pair, but the powergating registers
should be called individually. The hw handles power up/down
properly. The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both
crtcs in the pair are powered down. This simplifies
programming and should save additional power as the previous
code never actually power gated the crtc pair.

The ordering is important and the current drm code
wasn't cutting it for modern DIG encoders. We need
to have information about crtc before setting up
the encoders so I've shifted the ordering a bit.
Probably we'll need a full rework akin to danvet's
recent intel patchs. This patch fixes numerous
issues with DP bridge chips and makes link training
much more reliable.

Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
The DRM version is bumped, because RESOLVE_BOX is always rejected without this
fix on r600.

On some Fermi chipsets (NVCE particularly) PCOPY1 doesn't exist. And if
what I've seen on Kepler is true of Fermi too, chipsets of the same type
can have different PCOPY units available.
This should fix a v3.5 regression reported by a number of people effecting
suspend/resume on NVC8/NVCE chipsets.

If verify_parent_transid() fails for all mirrors, the current code
calls repair_io_failure() anyway which means:
- that the disk block is rewritten without repairing anything and
- that a kernel log message is printed which misleadingly claims
that a read error was corrected.
This is an example:
parent transid verify failed on 615015833600 wanted 110423 found 110424
parent transid verify failed on 615015833600 wanted 110423 found 110424
btrfs read error corrected: ino 1 off 615015833600 (dev /dev/...)
It is wrong to ignore the results from verify_parent_transid() and to
call repair_eb_io_failure() when the verification of the transids failed.
This commit fixes the issue.

(Btrfs: lock extents as we map them in DIO).
In dio write, we should unlock the section which we didn't do IO on in case that
we fall back to buffered write. But we need to not only unlock the section
but also cleanup reserved space for the section.
This bug was found while running xfstests 133, with this 133 no longer complains.

We can deadlock with freeze right now because we unconditionally start a
transaction in our ->sync_fs() call. To fix this just check and see if we
have a running transaction to commit. This saves us from the deadlock
because at this point we'll have the umount sem for the sb so we're safe
from freezes coming in after we've done our check. With this patch the
freeze xfstests no longer deadlocks. Thanks,
