This converts the panel-dsi-cm driver to use the transfer
API instead of specific functions, so that the specific
functions can be unexported and squashed into the generic
transfer function.

This prepares the driver for becoming a mipi_dsi_host implementation,
which provides a generic transfer function instead of all kind of
different read/write functions. The implementation will become more
elegant after unexporting the specific functions in the following
patches.

Implement CTM color management property for OMAP CRTC using DSS
overlay manager's Color Phase Rotation matrix. The CPR matrix does not
exactly match the CTM property documentation. On DSS the CPR matrix is
applied after gamma table look up. However, it seems stupid to add a
custom property just for that.

omapdrm supports gamma via GAMMA_LUT property. However, the HW we have
is:
gamma -> ctm -> out
instead of what the model DRM framework uses:
ctm -> gamma -> out
As the following patches add CTM support for omapdrm, lets first fix the
gamma.
This patch changes the property from GAMMA_LUT to DEGAMMA_LUT, and thus
we will have:
degamma -> ctm -> out
and the legacy ioctl will continue working as before.

The DRM core handles legacy gamma-set ioctl by setting GAMMA_LUT and
clearing CTM and DEGAMMA_LUT.
This works fine on HW where we have either:
degamma -> ctm -> gamma -> out
or
ctm -> gamma -> out
However, if the HW has gamma table before ctm, the atomic property
should be DEGAMMA_LUT, and thus we have:
degamma -> ctm -> out
This is fine for userspace which sets gamma table using the properties,
as the userspace can check for the existence of gamma & degamma, but the
legacy gamma-set ioctl does not work.
Change the DRM core to use DEGAMMA_LUT instead of GAMMA_LUT when the
latter is unavailable.

To support legacy gamma ioctls the drivers need to set
drm_crtc_funcs.gamma_set either to a custom implementation or to
drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the
latter.
We can simplify this by making the core handle it automatically.
Move the drm_atomic_helper_legacy_gamma_set() functionality into
drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use
drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.

the main difference being that we're using wait_for_flip_done instead of
wait_for_vblanks used in the drm_atomic_helper_commit_tail helper.
Let's switch to using drm_atomic_helper_commit.

The HVS state now has both unassigned_channels that reflects the
channels that are not used in the associated state, and the in_use
boolean for each channel that says whether or not a particular channel
is in use.
Both express pretty much the same thing, and we need the in_use variable
to properly track the commits, so let's get rid of unassigned_channels.

If we're having two subsequent, non-blocking, commits on two different
CRTCs that share no resources, there's no guarantee on the order of
execution of both commits.
However, the second one will consider the first one as the old state,
and will be in charge of freeing it once that second commit is done.
If the first commit happens after that second commit, it might access
some resources related to its state that has been freed, resulting in a
use-after-free bug.
The standard DRM objects are protected against this, but our HVS private
state isn't so let's make sure we wait for all the previous FIFO users
to finish their commit before going with our own.

Private objects storing a state shared across all CRTCs need to be
carefully handled to avoid a use-after-free issue.
The proper way to do this to track all the commits using that shared
state and wait for the previous commits to be done before going on with
the current one to avoid the reordering of commits that could occur.
However, this commit setup needs to be done after
drm_atomic_helper_setup_commit(), because before the CRTC commit
structure hasn't been allocated before, and before the workqueue is
scheduled, because we would be potentially reordered already otherwise.
That means that drivers currently have to roll their own
drm_atomic_helper_commit() function, even though it would be identical
if not for the commit setup.
Let's introduce a hook to do so that would be called as part of
drm_atomic_helper_commit, allowing us to reuse the atomic helpers.

Fix this by changing the chunk_sectors member of 'struct mddev' from

none of it appears to ever make use of signed int; and storing
positive signed int in unsigned is perfectly safe.

Commit
7705dc8557 ("x86/vmlinux: Use INT3 instead of NOP for linker fill bytes")
changed the padding bytes between functions from NOP to INT3. However,
when optprobe decodes a target function it finds INT3 and gives up the
jump optimization.
Instead of giving up any INT3 detection, check whether the rest of the
bytes to the end of the function are INT3. If all of them are INT3,
those come from the linker. In that case, continue the optprobe jump
optimization.

The new counters halt_poll_success_ns and halt_poll_fail_ns do not count
events. Instead they provide a time, and mess up our statistics. Therefore,
we should exclude them.
Removal is currently implemented with an exempt list. If more counters like
these appear, we can think about a more general rule like excluding all
fields name "*_ns", in case that's a standing convention.

Commit cae7ed3c2c ("KVM: x86: Refactor the MMIO SPTE generation handling")
cleaned up the computation of MMIO generation SPTE masks, however it
introduced a bug how the upper part was encoded:
SPTE bits 52-61 were supposed to contain bits 10-19 of the current
generation number, however a missing shift encoded bits 1-10 there instead
(mostly duplicating the lower part of the encoded generation number that
then consisted of bits 1-9).
In the meantime, the upper part was shrunk by one bit and moved by
subsequent commits to become an upper half of the encoded generation number
(bits 9-17 of bits 0-17 encoded in a SPTE).
In addition to the above, commit 56871d444b ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation")
has changed the SPTE bit range assigned to encode the generation number and
the total number of bits encoded but did not update them in the comment
attached to their defines, nor in the KVM MMU doc.
Let's do it here, too, since it is too trivial thing to warrant a separate
commit.
