We had a boot regression in Ux500 in the merge window because
two orthogonal pin control schemes for the PL011 were merged
at the same time:
- One using the .init() and .exit() hooks into the platform
for Ux500 putting the pins into default vs sleep state
respectively as the port was started/stopped.
commit a09806607f
"ARM: ux500: switch to using pinctrl for uart0"
- One hogging the default setting at PL011 probe()
commit 258e055111
"serial: amba-pl011: adopt pinctrl support"
To get a solution that works for both let's scrap the stuff
in the platform callbacks, instead have the driver itself
select default and sleep states when the port is
started/stopped. Hopefully this works for all clients.
Platform callbacks are bad for device tree migration anyway,
so this rids us of another problem in Ux500.

In the transmit path of the bonding driver, skb->cb is used to
stash the skb->queue_mapping so that the bonding device can set its
own queue mapping. This value becomes corrupted since the skb->cb is
also used in __dev_xmit_skb.
When transmitting through bonding driver, bond_select_queue is
called from dev_queue_xmit. In bond_select_queue the original
skb->queue_mapping is copied into skb->cb (via bond_queue_mapping)
and skb->queue_mapping is overwritten with the bond driver queue.
Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes
the packet length into skb->cb, thereby overwriting the stashed
queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit),
the queue mapping for the skb is set to the stashed value which is now
the skb length and hence is an invalid queue for the slave device.
If we want to save skb->queue_mapping into skb->cb[], best place is to
add a field in struct qdisc_skb_cb, to make sure it wont conflict with
other layers (eg : Qdiscc, Infiniband...)
This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8
bytes :
netem qdisc for example assumes it can store an u64 in it, without
misalignment penalty.
Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[].
The largest user is CHOKe and it fills it.

On gen4+ we have a bitfield to specify from which pipe the backlight
controller should take it's clock. For PCH split platforms we've
already set these up, but only at initialization time. And without
taking into account the 3rd pipe added with ivb.
For gen4, we've completely ignored these. Although we do restrict lvds
to the 2nd pipe, so this is only a problem on machines where we boot
up with the lvds on the first pipe.
So restructure the code to enable the backlight on the right pipe at
modeset time.
v2: For odd reasons panel_enable_backlight gets called twice in a
modeset, so we can't WARN_ON in there if the backlight controller is
switched on already.
v3: backlight enable can also be called through dpms on, so the check
in there is legit. Update the comment to reflect that.

- Use the BLM_ (for backlight modulation) prefix consistently.
- Note that combination mode (i.e. also taking the legacy backlight

- Move the new registers for PCH-split machines up, they're an almost

BLM_PCH_. Also add the pipe C select bit for ivb.
- Rip out the second pair of PCH polarity definitions - they're only

drm/radeon: fix tiling and command stream checking on evergreen v3
A regression was introduced in the 3.3 rc series, commit
"drm/ttm: simplify memory accounting for ttm user v2",
causing the metadata of buffer objects created using the ttm_bo_create()
function to be accounted twice.
That causes massive leaks with the vmwgfx driver running for example
SpecViewperf Catia-03 test 2, eventually killing the app.
Furthermore, the same commit introduces a regression where
metadata accounting is leaked if a buffer object is
initialized with an illegal size. This is also fixed with this commit.

Before Kernel 3.5, no one was checking for the return value of
drm_connector_attach_property, so we never noticed that we were unable
to create some properties. Commit "drm: WARN() when
drm_connector_attach_property fails" added a WARN when we fail to
create a property, and the transition from "connector properties" to
"object properties" changed the warning message a little bit.
On i915 machines with many TV connectors we hit the maximum number of
properties (since each TV connector uses a lot of properties), so we
get a few backtraces in our logs. This commit increases the maximum
number of properties to 24 hoping we'll have enough room for
everybody.
Chris suggested that we convert this code to "lists", but I believe
this conversion can come after we make sure people's dmesgs are not
spammed by our driver.
