The "GPL-2.0" SPDX license identifier is deprecated. Update the
code to use "GPL-2.0-only" instead. Choose this identifier over
"GPL-2.0-or-later" since it's the most restrictive of the two and it's
not fully clear that "GPL-2.0" also allows "GPL-2.0-or-later".

Engine was inappropriately used to refer to execution queues and it
also created some confusion with hardware engines. Where it applies
the exec_queue variable name is changed to q and comments are also
updated.

We cannot recover a VM if a rebind worker hits an error, ban the VM if
happens to ensure we do not attempt to place this VM on the hardware
again.
A follow up will inform the user if this happens.
v2: Return -ECANCELED in exec VM closed or banned, check for closed or
banned within VM lock.
v3: Fix lockdep splat by looking engine outside of vm->lock
v4: Fix error path when engine lookup fails
v5: Add debug message in rebind worker on error, update comments wrt
locking, add xe_vm_close helper

For long running (LR) jobs with the DRM scheduler we must return NULL in
run_job which results in signaling the job's finished fence immediately.
This prevents LR jobs from creating infinite dma-fences.
Signaling job's finished fence immediately breaks flow controlling ring
with the DRM scheduler. To work around this, the ring is flow controlled
and written in the exec IOCTL. Signaling job's finished fence
immediately also breaks the TDR which is used in reset / cleanup entity
paths so write a new path for LR entities.
v2: Better commit, white space, remove rmb(), better comment next to
emit_job()
v3 (Thomas): Change LR reference counting, fix working in commit

Sort includes and split them in blocks:
1) .h corresponding to the .c. Example: xe_bb.c should have a "#include
"xe_bb.h" first.
2) #include <linux/...>
3) #include <drm/...>
4) local includes
5) i915 includes
This is accomplished by running
`clang-format --style=file -i --sort-includes drivers/gpu/drm/xe/*.[ch]`
and ignoring all the changes after the includes. There are also some
manual tweaks to split the blocks.
v2: Also sort includes in headers

Leave the types as u64, but cast the pointers to unsigned long before
assigning so the compiler doesn't throw warning about casting a pointer
to integer of different size.
Also, size_t should use %zu, not %ld.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
