This commit adds a TODO list to the GPU driver developer's guide. The
content was taken from the DRMJanitors page on the X.Org wiki:
https://www.x.org/wiki/DRMJanitors/
The goal is to track a list of refactorings that would be nice to see
merged eventually. Sometimes these would be encountered during patch
review on the mailing list, and at other times one can come across
these while working in a specific area of code.

ZTE DRM driver updates for 4.11:
- Add missing selection of VIDEOMODE_HELPERS in Kconfig, since ZTE DRM
driver uses drm_display_mode_to_videomode().
- Enable HDMI audio support through SPDIF interface based on generic
hdmi-audio-codec driver.
- Enable VOU VL (Video Layer) to support overlay plane with scaling
function.
- Refine zx_vou driver a bit and then add TV Encoder output device
support.

Pull spi fixes from Mark Brown:
"The usual small smattering of driver specific fixes. A few bits that
stand out here:
- the R-Car patches adding fallbacks are just adding new compatible
strings to the driver so that device trees are written in a more
robustly future proof fashion, this isn't strictly a fix but it's
just new IDs and it's better to get it into mainline sooner to
improve the ABI
- the DesignWare "switch to new API part 2" patch is actually a
misleadingly titled fix for a bit that got missed in the original
conversion"

Pull networking fixes from David Miller:
1) Handle multicast packets properly in fast-RX path of mac80211, from
Johannes Berg.
2) Because of a logic bug, the user can't actually force SW
checksumming on r8152 devices. This makes diagnosis of hw
checksumming bugs really annoying. Fix from Hayes Wang.
3) VXLAN route lookup does not take the source and destination ports
into account, which means IPSEC policies cannot be matched properly.
Fix from Martynas Pumputis.
4) Do proper RCU locking in netvsc callbacks, from Stephen Hemminger.
5) Fix SKB leaks in mlxsw driver, from Arkadi Sharshevsky.
6) If lwtunnel_fill_encap() fails, we do not abort the netlink message
construction properly in fib_dump_info(), from David Ahern.
7) Do not use kernel stack for DMA buffers in atusb driver, from Stefan
Schmidt.
8) Openvswitch conntack actions need to maintain a correct checksum,
fix from Lance Richardson.
9) ax25_disconnect() is missing a check for ax25->sk being NULL, in
fact it already checks this, but not in all of the necessary spots.
Fix from Basil Gunn.
10) Action GET operations in the packet scheduler can erroneously bump
the reference count of the entry, making it unreleasable. Fix from
Jamal Hadi Salim. Jamal gives a great set of example command lines
that trigger this in the commit message.

Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.
For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

git://anongit.freedesktop.org/git/drm-misc into drm-next
First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
dma-buf kerneldoc patches
It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during
this time might be useful.
I'd also like to backmerge -rc2+this into drm-intel next week, we have
quite a pile of patches waiting for the stuff in here.

The feature from Geert is on top of v4.10 merge window commit

I figured it would just easier than me trying than to cherry-pick the

IOMMU initialization issue related to the DMAR table missing, remove
an excessive function call from the core ACPI code, update an error

problems with unhandled GPE notifications.
Specifics:
- Fix a device enumeration issue leading to incorrect associations
between ACPI device objects and platform device objects
representing physical devices if the given device object has both
_ADR and _HID (Rafael Wysocki).
- Avoid passing NULL to acpi_put_table() during IOMMU initialization

Some SoC without MMU have display driver where a drm/kms driver
could be implemented.
Before doing such kind of thing drm/kms must allow to use mmuless devices.
This patch propose to remove MMU configuration flag and add a cma helper
function to help implementing mmuless display driver
version 4:
- add documentation about drm_gem_cma_get_unmapped_area()
- stub it MMU case

Pull ARM SoC fixes from Arnd Bergmann:
"This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
regressions introduced during the merge window, and about half of the
changes are for mach-omap2.
A couple of patches are just cleanups and dead code removal that I
would not normally have considered for merging after -rc2, but I
decided to take them along with the fixes this time.
Notable fixes include:
- removing the skeleton.dtsi include broke a number of machines, and
we have to put empty /chosen nodes back to be able to pass kernel
command lines as before
- enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as
it had been for no good reason for a long time"

Fist set of fixes for omaps for v4.10-rc cycle, mostly
to deal with various regressions noticed during the merge

is now dead code with device tree based booting that should
be OK for the early -rc cycle:
- A series of fixes to add empty chosen node to fix regressions
caused for bootloaders that don't create chosen node as the
decompressor needs the chosen node to merge command line and
ATAGs into it

- Fix wrong strcat for non-NULL terminated string
- A series of changes to fix tps65217 interrupts to not use
defines as we don't do that for interrupts
- Two patches to fix USB VBUS detection on am57xx-idk and force it
to peripheral mode until dwc3 role detection is working

accidentally left out of an earlier patch
- Fix n900 eMMC detection when booted on qemu
- Remove unwanted pr_err on failed memory allocation for
