The DU parallel interface ODDF signal is optional, move it out of the
HSYNC/VSYNC group into a group of its down. The CDE and DISP signals are
independent, split them to two different groups.

This driver is only useful on MSM8x74, so let the driver depend on
ARCH_QCOM but allow compile coverage testing.
The main benefit is that the driver isn't available to be selected for
machines that don't have the matching hardware.

This lets the gpiolib core handle the irqchip set-up and
chained IRQ on the primary (behind the mux) IRQ chip in
the st pinctrl driver.
Default irq type is set to level low at irqchip add time.
The v1 was sent by Linus
(https://lkml.org/lkml/2014/4/4/287).
Two changes were necessary to make it to work properly
on STiH416:
1 - dev reference was not passed to the gpio_chip
struct, causing a panic.
2 - gpiochip_irqchip_add passed IRQ_TYPE_NONE as
default type, which caused lot of warnings at
init time. I choose IRQ_TYPE_LEVEL_LOW as default.

In the mass-conversion to the new irqchip callbacks, this

John W. Linville says:
====================
pull request: wireless 2014-04-17
Please pull this batch of fixes intended for the 3.15 stream...
For the mac80211 bits, Johannes says:
"We have a fix from Chun-Yeow to not look at management frame bitrates
that are typically really low, two fixes from Felix for AP_VLAN
interfaces, a fix from Ido to disable SMPS settings when a monitor
interface is enabled, a radar detection fix from Michał and a fix from
myself for a very old remain-on-channel bug."
For the iwlwifi bits, Emmanuel says:
"I have new device IDs and a new firmware API. These are the trivial
ones. The less trivial ones are Johannes's fix that delays the
enablement of an interrupt coalescing hardware until after association
- this fixes a few connection problems seen in the field. Eyal has a
bunch of rate control fixes. I decided to add these for 3.15 because
they fix some disconnection and packet loss scenarios which were
reported by the field. I also have a fix for a memory leak that
happens only with a very new NIC."
Along with those...
Amitkumar Karwar fixes a couple of problems relating to driver/firmware
interactions in mwifiex.
Christian Engelmayer avoids a couple of potential memory leaks in
the new rsi driver.
Eliad Peller provides a wl18xx mailbox alignment fix for problems
when using new firmware.
Frederic Danis adds a couple of missing debugging strings to the
cw1200 driver.
Geert Uytterhoeven adds a variable initialization inside of the
rsi driver.
Luciano Coelho patches the wlcore code to ignore dummy packet events
in PLT mode in order to work around a firmware bug.

The patch fixes a problem with dropped jumbo frames after usage of
'ethtool -G ... rx'.
Scenario:
1. ip link set eth0 up
2. ethtool -G eth0 rx N # <- This zeroes rx-jumbo
3. ip link set mtu 9000 dev eth0
The ethtool command set rx_jumbo_pending to zero so any received jumbo
packets are dropped and you need to use 'ethtool -G eth0 rx-jumbo N'
to workaround the issue.
The patch changes the logic so rx_jumbo_pending value is changed only if
jumbo frames are enabled (MTU > 1500).

This is leftover stuff from my previous doc round which I kinda wanted
to do but didn't yet due to rebase hell.
The modeset helpers and the probing helpers a independent and e.g.
i915 uses the probing stuff but has its own modeset infrastructure. It
hence makes to split this up. While at it add a DOC: comment for the
probing libraray.
It would be rather neat to pull some of the DocBook documenting these
two helpers into in-line DOC: comments. But unfortunately kerneldoc
doesn't support markdown or something similar to make nice-looking
documentation, so the current state is better.

After thinking about this topic a bit more I've reached the conclusion
that implementing this doesn't make sense:
- The locking is all wrong: set_config(NULL) will also unlink encoders
and connectors, but those links are protected with the mode_config
mutex. In the ->disable_plane callback we only hold all modeset
locks, but eventually we want to switch to just grabbing the
per-crtc (and maybe per-plane) locks as needed, maybe based on
ww_mutexes. Having a callback which absolutely needs all modeset
locks is bad for this conversion.
Note that the same isn't true for the provided ->update_plane since
we've audited the crtc helpers to make sure that not encoder or
connector links are changed.
- There's no way to re-enable the plane with an ->update_plane: The
connectors/encoder links are lost and so we can't re-enable the
CRTC. Even without that issue the driver might have reassigned some
shared resources (as opposed to e.g. DPMS off, where drivers are not
allowed to do that to make sure the CRTC can be enabled again).
- The semantics don't make much sense: Userspace asked to scan out
black (or some other color if the driver supports a background
color), not that the screen be disabled.
- Implementing proper primary plane support (i.e. actually disabling
the primary plane without disabling the CRTC) is really simple, at
least if all the hw needs is flipping a bit. The big task is
auditing all the interactions with other ioctls when the CRTC is on
but there's no primary plane (e.g. pageflips). And some of that work
still needs to be done.

Commit 457e77b26428ab4a24998eecfb99f27fa4195397 added two checks applied to a
value received from nv_rd32(bios, 0x619f04). But after this new piece of code
is executed, the addr local variable does not hold the same value it used to
hold before the commit. Here is what is was assigned in the original code:
(u64)(nv_rd32(bios, 0x619f04) & 0xffffff00) << 8
in the committed code it ends up with this value:
(u64)(nv_rd32(bios, 0x619f04) >> 8) << 8
These expressions are obviously not equivalent.
My Nvidia video card does not show anything on the display when I boot a

The patch fixes the code so that the new checks are still done, but the
side effect of an incorrect addr value is gone.

drm/tegra: Fixes for v3.15-rc2
This contains a fix for the host1x driver writing to non-existent syncpt
registers.
A second commit removes an excess pad field in the parameter structure
for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this
file indicates that this was once there to pad an uneven number of u32
u32 fields, of which one was subsequently removed. Unfortunately nobody
remembered to get rid of the padding when that happened.
Both of these commits are Cc: stable because they fix issues that were
introduced back in v3.10.

Merge ipmi fixes from Corey Minyard:
"Things collected since last kernel release.
Some of these are pretty important. The first three are bug fixes.
The next two are to hopefully make everyone happy about allowing
ACPI to be on all the time and not have IPMI have an effect on the
system when not in use. The last is a little cleanup"
* emailed patches from Corey Minyard <cminyard@mvista.com>:
ipmi: boolify some things
ipmi: Turn off all activity on an idle ipmi interface
ipmi: Turn off default probing of interfaces
ipmi: Reset the KCS timeout when starting error recovery
ipmi: Fix a race restarting the timer
Char: ipmi_bt_sm, fix infinite loop

The IPMI driver would wake up periodically looking for events and
watchdog pretimeouts. If there is nothing waiting for these events,
it's really kind of pointless to be checking for them. So modify the
driver so the message handler can pass down if it needs the lower layer
to be waiting for these. Modify the system interface lower layer to
turn off all timer and thread activity if the upper layer doesn't need
anything and it is not currently handling messages. And modify the
message handler to not restart the timer if its timer is not needed.
The timers and kthread will still be enabled if:
- the SI interface is handling a message.
- a user has enabled watching for events.
- the IPMI watchdog timer is in use (since it uses pretimeouts).
- the message handler is waiting on a remote response.
- a user has registered to receive commands.
This mostly affects interfaces without interrupts. Interfaces with
interrupts already don't use CPU in the system interface when the
interface is idle.

With recent changes it is possible for the timer handler to detect an
idle interface and not start the timer, but the thread to start an
operation at the same time. The thread will not start the timer in that
instance, resulting in the timer not running.
Instead, move all timer operations under the lock and start the timer in
the thread if it detect non-idle and the timer is not already running.
Moving under locks allows the last timeout to be set in both the thread
and the timer. 'Timer is not running' means that the timer is not
pending and smi_timeout() is not running. So we need a flag to detect
this correctly.
Also fix a few other timeout bugs: setting the last timeout when the
interrupt has to be disabled and the timer started, and setting the last
timeout in check_start_timer_thread possibly racing with the timer

In read_all_bytes, we do
unsigned char i;
...
bt->read_data[0] = BMC2HOST;
bt->read_count = bt->read_data[0];
...
for (i = 1; i <= bt->read_count; i++)
bt->read_data[i] = BMC2HOST;
If bt->read_data[0] == bt->read_count == 255, we loop infinitely in the
'for' loop. Make 'i' an 'int' instead of 'char' to get rid of the
overflow and finish the loop after 255 iterations every time.
