First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
to userspace. I also had the i915 patch in here, but that had a
small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time. They're discarded for vmlinux but they
should also be discarded for modules.
Since this is a recurring pattern, prefix the section names with
".discard.". It's a nice convention and vmlinux.lds.h already discards
such sections.
Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.

For consistency with other reference counting APIs in the kernel, add
drm_property_blob_get() and drm_property_blob_put() to reference count
DRM blob properties.
Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.
A semantic patch is provided that can be used to convert all drivers to

Miscellanea:
- Correct the misuse of type string PRINTF_0xDECIMAL type strings are
supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the
type check in case I forget this again sometime in the future.
- Improve the mechanism to find these defects so all 3 current checks

"Highlights include:
- optimized memset and memcpy routines, ~20% boot time saving
- support for cpu idling
- adding support for l.swa and l.lwa atomic operations (in spec from
2014)
- use atomics to implement: bitops, cmpxchg, futex
- the atomics are in preparation for SMP support"

Lines containing "} else {" should not be detected as unbalanced braces.
But the second check can be reduced to ".+else\s*{" and it therefore
never checked if the beginning of a line contains any other character
(like the relevant "}"). This check would also return true for "} else
{" and create warnings like
CHECK: Unbalanced braces around else statement
#391: FILE: ./net/batman-adv/tvlv.c:391:
+ } else {
The check can be changed to check the whole line for the missing "}" to
avoid this false positive.
Fixes: 0d1532456c26 ("checkpatch: notice unbalanced else braces in a patch")

Embedded function names are less appropriate to use when refactoring can
cause function renaming. Prefer the use of "%s", __func__ to embedded
function names.
