Access to SQ_EDC_INFO requires selecting register instance and
hence mutex lock when accessing GRBM_GFX_INDEX for which a work
is schedueled from IH. But SQ interrupt can be raised on many instances
at once which means queuing work will usually succeed for the first one
but fail for the rest since the work takes time to process. To avoid
losing info about other interrupt instances call the parsing function
directly from high IRQ when current work hasn't finished and avoid
accessing SQ_EDC_INFO in that case.

issue:
there are VMC page fault occurred if force APP kill during
3dmark test, the cause is in entity_fini we manually signal
all those jobs in entity's queue which confuse the sync/dep
mechanism:
1)page fault occurred in sdma's clear job which operate on
shadow buffer, and shadow buffer's Gart table is cleaned by
ttm_bo_release since the fence in its reservation was fake signaled
by entity_fini() under the case of SIGKILL received.
2)page fault occurred in gfx' job because during the lifetime
of gfx job we manually fake signal all jobs from its entity
in entity_fini(), thus the unmapping/clear PTE job depend on those
result fence is satisfied and sdma start clearing the PTE and lead
to GFX page fault.
fix:
1)should at least wait all jobs already scheduled complete in entity_fini()
if SIGKILL is the case.
2)if a fence signaled and try to clear some entity's dependency, should
set this entity guilty to prevent its job really run since the dependency
is fake signaled.
v2:
splitting drm_sched_entity_fini() into two functions:
1)The first one is does the waiting, removes the entity from the
runqueue and returns an error when the process was killed.
2)The second one then goes over the entity, install it as
completion signal for the remaining jobs and signals all jobs

NULL pointer is because original logic will step into
set_pde_pte() even after the gart.ptr is freed due to
there are twice gart_unbind() on all gart area.
also, there are other minor fixes:
1,since gart_init only create dummy page, the corresponding
gart_fini shouldn't do more like unbinding all GART, this is
unnecessary because in driver fini stage all GART unbinding
had already been done during each IP's SW_FINI (GMC's
SW_FINI is the last one called), so remove the step
for the GART unbinding in gart_fini().
2,gart_fini() is already invoked during each GMC IP's gart_fini
routine,e.g. gmc_vx_0_gart_fini(), so no need to manually
call it during ttm_fini().

Merge tag 'drm-for-v4.15-amd-dc' of git://people.freedesktop.org/~airlied/linux
Pull amdgpu DC display code for Vega from Dave Airlie:
"This is the pull request for the AMD DC (display code) layer which is
a requirement to program the display engines on the new Vega and Raven
based GPUs. It also contains support for all amdgpu supported GPUs
(CIK, VI, Polaris), which has to be enabled. It is also a kms atomic
modesetting compatible driver (unlike the current in-tree display
code).
I've kept it separate from drm-next because it may have some things
that cause you to reject it.
Background story:
AMD have an internal team creating a shared OS codebase for display at
hw bring up time using information from their hardware teams. This
process doesn't lead to the most Linux friendly/looking code but we
have worked together on cleaning a lot of it up and dealing with
sparse/smatch/checkpatch, and having their team internally adhere to
Linux coding standards.
This tree is a complete history rebased since they started opening it,
we decided not to squash it down as the history may have some value.
Some of the commits therefore might not reach kernel standards, and we
are steadily training people in AMD to better write commit msgs.
There is a major bunch of generated bandwidth calculation and
verification code that comes from their hardware team. On Vega and
before this is float calculations, on Raven (DCN10) this is double
based. They do the required things to do FP in the kernel, and I could
understand this might raise some issues. Rewriting the bandwidth would
be a major undertaken in reverification, it's non-trivial to work out
if a display can handle the complete set of mode information thrown at
it.
Future story:
There is a TODO list with this, and it address most of the remaining
things that would be nice to refine/remove. The DCN10 code is still
under development internally and they push out a lot of patches quite
regularly and are supporting this code base with their display team. I
think we've reached the point where keeping it out of tree is going to
motivate distributions to start carrying the code, so I'd prefer we
get it in tree. I think this code is slightly better than STAGING
quality but not massively so, I'd really like to see that float/double
magic gone and fixed point used, but AMD don't seem to think the
accuracy and revalidation of the code is worth the effort"

Register accessing is performed when IRQ is disabled. Never sleep in
this function.
Known issue: dead sleep in many use cases of index/data registers.
v2:
- wrap polling fence functions.
- don't trigger IRQ for polling in case of wrongly fence signal.
v3:
- handle wrap round gracefully.
- add comments for polling function
v4:
- don't return negative timeout confused with error code
