Scattering of random drm core patches. Bunch of atomic prep work too, but
the final bits for blob properties, atomic modesets and lifting the
experimental tag on the atomic ioctl are still blocked on Daniel Stone
finalizing and testing the weston support for it. I hope that we can get
it all ready for 4.2 though.

...
Drivers may need to store the state of shared resources, such as PLLs
or FIFO space, into the atomic state. Allow this by making it possible
to subclass drm_atomic_state.
Changes since v1:
- Change member names for functions to atomic_state_(alloc,clear)
- Change __drm_atomic_state_new to drm_atomic_state_init
- Allow free function to be overridden too, in case extra memory is
allocated in alloc.
Changes since v2:
- Rename *_default_free to default_release, to make clear it doesn't
free the state object itself.

Commit 4f71d0cb76 ("drm/dp: add a hw mutex around the transfer
functions. (v2)"), renamed the functions drm_dp_aux_register_i2c_bus()
and drm_dp_aux_unregister_i2c_bus() to drm_dp_aux_register() and
drm_dp_aux_unregister(), respectively. However, a comment referring to
the original names was not updated in the DP helper header file. Hence,
correct these names.

This is useful for drivers which have their own modeset infrastructure
but want to reuse most of the legacy state frobbery from the helpers.
i915 wants this.

Displayport compliance test 4.2.2.6 requires that a source device be capable of
detecting a corrupt EDID. The test specification states that the sink device
sets up the EDID with an invalid checksum. To do this, the sink sets up an
invalid EDID header, expecting the source device to generate the checksum and
compare it to the value stored in the last byte of the block data.
Unfortunately, the DRM EDID reading and parsing functions are actually too good
in this case; the header is fixed before the checksum is computed and thus the
test never sees the invalid checksum. This results in a failure to pass the
compliance test.
To correct this issue, when the EDID code detects that the header is invalid,
a flag is set to indicate that the EDID is corrupted. In this case, it sets
edid_corrupt flag and continues with its fix-up code. This flag is also set in
the case of a more seriously damaged header (fixup score less than the
threshold). For consistency, the edid_corrupt flag is also set when the
checksum is invalid as well.
V2:
- Removed the static bool global
- Added a bool to the drm_connector struct to reaplce the static one for
holding the status of raw edid header corruption detection
- Modified the function signature of the is_valid function to take an
additional parameter to store the corruption detected value
- Fixed the other callers of the above is_valid function
V3:
- Updated the commit message to be more clear about what and why this
patch does what it does.
- Added comment in code to clarify the operations there
- Removed compliance variable and check_link_status update; those
have been moved to a later patch
- Removed variable assignment from the bottom of the test handler
V4:
- Removed i915 tag from subject line as the patch is not i915-specific
V5:
- Moved code causing a compilation error to this patch where the variable
is actually declared
- Maintained blank lines / spacing so as to not contaminate the patch
V6:
- Removed extra debug messages
- Added documentation to for the added parameter on drm_edid_block_valid
- Fixed more whitespace issues in check_link_status
- Added a clear of the header_corrupt flag to the end of the test handler
in intel_dp.c
- Changed the usage of the new function prototype in several places to use
NULL where it is not needed by compliance testing
V7:
- Updated to account for long_pulse flag propagation
V8:
- Removed clearing of header_corrupt flag from the test handler in intel_dp.c
- Added clearing of header_corrupt flag in the drm_edid_block_valid function
V9:
- Renamed header_corrupt flag to edid_corrupt to more accurately reflect its
value and purpose
- Updated commit message
V10:
- Updated for versioning and patch swizzle
- Revised the title to more accurately reflect the nature and contents of
the patch
- Fixed formatting/whitespace problems
- Added set flag when computed checksum is invalid

The magic auth tokens we have are a simple map from cyclic IDs to drm_file
objects. Remove all the old bulk of code and replace it with a simple,
direct IDR.
The previous behavior is kept. Especially calling authmagic multiple times
on the same magic results in EINVAL except on the first call. The only
difference in behavior is that we never allocate IDs multiple times as
long as a client has its FD open.
v2:
- Fix return code of GetMagic()
- Use non-cyclic IDR allocator
- fix off-by-one in "magic > INT_MAX" sanity check
v3:
- drop redundant "magic > INT_MAX" check

This was a bit too much cargo-culted, so lets make it solid:
- vblank->count doesn't need to be an atomic, writes are always done
under the protection of dev->vblank_time_lock. Switch to an unsigned
long instead and update comments. Note that atomic_read is just a
normal read of a volatile variable, so no need to audit all the
read-side access specifically.
- The barriers for the vblank counter seqlock weren't complete: The
read-side was missing the first barrier between the counter read and
the timestamp read, it only had a barrier between the ts and the
counter read. We need both.
- Barriers weren't properly documented. Since barriers only work if
you have them on boths sides of the transaction it's prudent to
reference where the other side is. To avoid duplicating the
write-side comment 3 times extract a little store_vblank() helper.
In that helper also assert that we do indeed hold
dev->vblank_time_lock, since in some cases the lock is acquired a
few functions up in the callchain.
Spotted while reviewing a patch from Chris Wilson to add a fastpath to
the vblank_wait ioctl.
v2: Add comment to better explain how store_vblank works, suggested by
Chris.
v3: Peter noticed that as-is the 2nd smp_wmb is redundant with the
implicit barrier in the spin_unlock. But that can only be proven by
auditing all callers and my point in extracting this little helper was
to localize all the locking into just one place. Hence I think that
additional optimization is too risky.
