The etnaviv_gem_prime_get_sg_table() is supposed to return error
pointers. Otherwise it can lead to a NULL dereference when it's called
from drm_gem_map_dma_buf().

Decauple sched threads stop and start and ring mirror
list handling from the policy of what to do about the
guilty jobs.
When stoppping the sched thread and detaching sched fences
from non signaled HW fenes wait for all signaled HW fences
to complete before rerunning the jobs.
v2: Fix resubmission of guilty job into HW after refactoring.
v4:
Full restart for all the jobs, not only from guilty ring.
Extract karma increase into standalone function.
v5:
Rework waiting for signaled jobs without relying on the job
struct itself as those might already be freed for non 'guilty'
job's schedulers.
Expose karma increase to drivers.
v6:
Use list_for_each_entry_safe_continue and drm_sched_process_job
in case fence already signaled.
Call drm_sched_increase_karma only once for amdgpu and add documentation.
v7:
Wait only for the latest job's fence.

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.
It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access. But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.
A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model. And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.
This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
There were a couple of notable cases:
- csky still had the old "verify_area()" name as an alias.
- the iter_iov code had magical hardcoded knowledge of the actual
values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
really used it)
- microblaze used the type argument for a debug printout
but other than those oddities this should be a total no-op patch.
I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something. Any missed conversion should be trivially fixable, though.

The only event function that is called from IRQ context is event_free,
which is already using atomic bitmap operations, so we can avoid taking
the event spinlock in this function completely. As other the other
functions still using the event spinlock are all called from normal

This patch adds two new functions to help client drivers suspend and
resume the scheduler job timeout. This can be useful in cases where the
hardware has preemption support enabled. Using this, it is possible to have
the timeout active only for the ring which is active on the ringbuffer.
This patch also makes the job_list_lock IRQ safe.

The etnaviv device is a virtual device backing the DRM device, which may
drive multiple hardware GPU core devices. As most of the dma-mapping handling
is done through the virtual device, we need to make sure that a proper DMA
setup is in place. The easiest way to get a reasonable configuration is
to let the virtual device share the DMA configuration with one of the GPU
devices, so call of_dma_configure() with the right parameters manually.
This assumes that all etnaviv driven GPU devices in the system share the
same DMA configuration. If we ever encounter a SoC where the GPUs are on
busses with different offsets or behind different IOMMUs that will require
much deeper changes to the driver, as we would need to implement etnaviv
specific versions of most of the DRM helper functions.
For now we should be fine with this solution.

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.
Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t")
Previously vm_insert_page() returns err which driver
mapped into VM_FAULT_* type. The new function
vmf_insert_page() will replace this inefficiency by
returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function

Everything in the flush code path (i.e. waiting for SW queue
to become empty) names with *_flush()
and everything in the release code path names *_fini()
This patch also effect the amdgpu and etnaviv drivers which
use those functions.
v2:
Also pplay the change to vd3.

When the hangcheck handler was replaced by the DRM scheduler timeout
handling we dropped the forward progress check, as this might allow
clients to hog the GPU for a long time with a big job.
It turns out that even reasonably well behaved clients like the
Armada Xorg driver occasionally trip over the 500ms timeout. Bring
back the forward progress check to get rid of the userspace regression.
We would still like to fix userspace to submit smaller batches
if possible, but that is for another day.

dma_fence_default_wait is the default now, same for the trivial
enable_signaling implementation.

Commit 246774d17fc0 ("drm/etnaviv: remove the need for a gpu-subsystem
DT node") introduced DRM registration via
platform_device_register_simple(), but missed to call
platform_device_unregister() inside etnaviv_exit().
Fix the problem by calling platform_device_unregister() inside
etnaviv_exit(). While at it, also rearrange the function calls
in the exit path to make them happen in the opposite order of
registration.
Tested on a imx6-sabresd board.

platform_device_register_simple() may fail, so we should better
check its return value and propagate it in the case of error.

So what we have for this cycle is a bit of spring cleaning with removal
of unused register logging code and getting rid of the license text in
favor of SPDX, a few smaller MMU handling improvements and a timeout
calculation change, fixing premature fence wait timeouts after 50 days
of uptime.
