commit 86d65b7e7a0c927d07d18605c276d0f142438ead upstream.
gcc-6 warns about code in the nouveau driver that is obviously silly:
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
if (pm->sequence != pm->sequence) {
The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.
This patch restores the original behavior.

commit 47a66e45d7a7613322549c2475ea9d809baaf514 upstream.
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

commit d31ed3f05763644840c654a384eaefa94c097ba2 upstream.
The code is applying the same scaling for the X and Y components,
thus making the scaling feature only functional when both components
have the same scaling factor.
Do the s/_w/_h/ replacement where appropriate to fix vertical scaling.

commit 44eb0cb9620c6a53ec8e7073262e2af8079b727f upstream.
VMA offsets are 64 bits. Plane surface offsets are in ggtt and
the hardware register to set this is thus 32 bits. Be explicit
about these and convert carefully to from vma to final size.
This will make sparse happy by not creating 32bit pointers out
of 64bit vma offsets.

commit 166c5a6ef765653848161e6f4af81c05e4b3ecf6 upstream.
In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to
gma500") the legacy i2c helpers were moved to the only remaining user of
them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus()
was marked deprecated and started warning about its remaining use.
It's now been a year and a half of annoying warning, and apparently
nobody cares enough about gma500 to try to move it along to the more
modern models.
Get rid of the warning - if even the gma500 people don't care enough,
then they should certainly not spam other innocent developers with a
warning that might hide other, much more real issues.

Cx ipeak driver will throttle cDSP frequency if all

Using per uts namespace utsname() for kernel build information section
in snapshot dump was causing a kernel panic because it is accessing a
NULL nsproxy pointer. nsproxy was null because corresponding user task
got SIGKILL which triggered call to free_nsproxy. The patch fixes the
issue by using the global init_utsname() which is always valid.

Currently all connectors list SDE as their parent interrupt
controller.
With commit <f5dd86c92d63df7a2790149d1cb9588c004695b0>
(<drm/msm/sde: reorganize top level interrupt handling code>),
the SDE IRQ domains get added after DRM init functions of the
connectors. This is incorrect as the irq request calls of the
connectors shall fail if the domain of the parent is not added yet.
Fix this by re-ordering the sde_kms_int() function to reflect the
correct order and remove the IRQ domain addition from irq_preinstall
calls as that will be very late for the connectors.

Return the current status of the fence (0 for retired, -EBUSY for
active) if an absolute timeout of 0 is passed to MSM_IOCTL_WAIT_FENCE.
This allows the user space to check the status of the fence without
an awkward timeout or an inadvertent kernel message.
