commit 62d1a752874962f072de8a779e960fcd2ab4847b upstream.
v3d_bo_get_pages() checks this to decide to map the imported buffer
instead of the backing shmem file. The caller was about to set this
value anyway, and there's no error path in between. Ideally we
wouldn't even allocate the shmem file for our imports, but that's a
more invasive fix.

commit 17e23993f297467bae946a46e44f945d8dae93f8 upstream.
The v3d_fence_create() only returns error pointers on error. It never
returns NULL.

[ Upstream commit 7122b68b8a9692dcc3acf89595f04c492872115f ]
Between creation and queueing of a job, you need to prevent any other
job from being created and queued. Otherwise the scheduler's fences
may be signaled out of seqno order.
v2: move mutex unlock to the error label.

drm-misc-next-fixes for v4.18:
Driver changes:

Without CONFIG_MMU, we get a link error:
drivers/gpu/drm/v3d/v3d_bo.o: In function `v3d_gem_fault':
v3d_bo.c:(.text+0x3ca): undefined reference to `vm_insert_mixed'
The other drivers with this problem already depend on CONFIG_MMU,
so let's do the same thing here.

into drm-next
Main changes for 4.18. I'd like to do a separate pull for vega20 later
this week or next. Highlights:
- Reserve pre-OS scanout buffer during init for seemless transition from
console to driver
- VEGAM support
- Improved GPU scheduler documentation
- Initial gfxoff support for raven
- SR-IOV fixes
- Default to non-AGP on PowerPC for radeon
- Fine grained clock voltage control for vega10
- Power profiles for vega10
- Further clean up of powerplay/driver interface
- Underlay fixes
- Display link bw updates
- Gamma fixes
- Scatter/Gather display support on CZ/ST
- Misc bug fixes and clean ups

This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.
V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme. This massively changes the
GEM behavior, so I've forked off to a new driver.
v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild
test robot. Drop personal git link from MAINTAINERS. Don't
double-map dma-buf imported BOs. Add kerneldoc about needing MMU
eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup
to mmap time. Use drm_dev_init instead of _alloc. Use
ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage,
since we don't modeset. Switch page tables back to WC (debug
change to coherent had slipped in). Switch
drm_gem_object_unreference_unlocked() to
drm_gem_object_put_unlocked(). Simplify overflow mem handling by
not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
other ioctls.
