Both the fence and event alloc are safe to be done without holding the GPU
lock, as they either don't need any locking (fences) or are protected by
their own lock (events).
This solves a bad locking interaction between the submit path and the
recover worker. If userspace manages to exhaust all available events while
the GPU is hung, the submit will wait for events to become available
holding the GPU lock. The recover worker waits for this lock to become
available before trying to recover the GPU which frees up the allocated
events. Essentially both paths are deadlocked until the submit path
times out waiting for available events, failing the submit that could
otherwise be handled just fine if the recover worker had the chance to
bring the GPU back in a working state.

ARM SMCCC is only set for ARMv7 and ARMv8 CPUs, but we currently
allow the driver to be build for older architecture levels as
well, which results in a link failure:
drivers/gpu/built-in.o: In function `mtk_hdmi_hw_make_reg_writable':
:(.text+0x1e737c): undefined reference to `arm_smccc_smc'
This adds a Kconfig dependency. The patch applies on my two
previous fixes that are not yet applied, so please apply all
three to get randconfig builds to work correctly.

This function would call drm_modeset_lock_all, while the suspend/resume
functions already have their own locking. Fix this by factoring out
__intel_display_resume, and calling the atomic helpers for duplicating
atomic state and disabling all crtc's during suspend.
Changes since v1:
- Deal with -EDEADLK right after lock_all and clean up calls
to hw readout.
- Always take all modeset locks so updates during gpu reset are blocked.
Changes since v2:
- Fix deadlock in intel_update_primary_planes.
- Move WARN_ON(EDEADLK) to __intel_display_resume.
- pctx -> ctx
- only call __intel_display_resume on success in intel_display_resume.
Changes since v3:
- Rebase on top of dev_priv -> dev change.
- Use drm_modeset_lock_all_ctx instead of drm_modeset_lock_all.
Changes since v4 [by vsyrjala]:
- Deal with skip_intermediate_wm
- Update comment w.r.t. mode_config.mutex vs. ->detect()
- Rebase due to INTEL_GEN() etc.

Erratum SKL075: Display Flicker May Occur When Both VT-d And FBC Are Enabled
"Display flickering may occur when both FBC (Frame Buffer Compression)
and VT - d (Intel® Virtualization Technology for Directed I/O) are enabled
and in use by the display controller."
Ville found the w/a name in the database:
WaFbcTurnOffFbcWhenHyperVisorIsUsed:skl,bxt and also dug out that it
affects Broxton.
v2: Log when the quirk is applied.
v3: Ensure i915.enable_fbc is false when !HAS_FBC()
v4: Fix function name after rebase
v5: Add Broxton to the workaround
Note for backporting to stable, we need to add
#define mkwrite_device_info(ptr) \
((struct intel_device_info *)INTEL_INFO(ptr))
