drm/xe: Convert the CPU fault handler for exhaustive eviction

The CPU fault handler may populate bos and migrate, and in doing
so might interfere with other tasks validating.

Rework the CPU fault handler completely into a fastpath
and a slowpath. The fastpath trylocks only the validation lock
in read-mode. If that fails, there's a fallback to the
slowpath, where we do a full validation transaction.

This mandates open-coding of bo locking, bo idling and
bo populating, but we still call into TTM for fault
finalizing.

v2:
- Rework the CPU fault handler to actually take part in
the exhaustive eviction scheme (Matthew Brost).
v3:
- Don't return anything but VM_FAULT_RETRY if we've dropped the
mmap_lock. Not even if a signal is pending.
- Rebase on gpu_madvise() and split out fault migration.
- Wait for idle after migration.
- Check whether the resource manager uses tts to determine
whether to map the tt or iomem.
- Add a number of asserts.
- Allow passing a ttm_operation_ctx to xe_bo_migrate() so that
it's possible to try non-blocking migration.
- Don't fall through to TTM on migration / population error
Instead remove the gfp_retry_mayfail in mode 2 where we
must succeed. (Matthew Brost)
v5:
- Don't allow faulting in the imported bo case (Matthew Brost)

drm/xe: Introduce an xe_validation wrapper around drm_exec

Introduce a validation wrapper xe_validation_guard() as a helper
intended to be used around drm_exec transactions what perform
validations. Once TTM can handle exhaustive eviction we could
remove this wrapper or make it mostly a NO-OP unless other
functionality is added to it.

Currently the wrapper takes a read lock upon entry and if the
transaction hits an OOM, all locks are released and the
transaction is retried with a write-lock. If all other
validations participate in this scheme, the transaction with
the write lock will be the only transaction validating and
should have access to all available non-pinned memory.

There is currently a problem in that TTM converts -EDEADLOCKS to
-ENOMEM, and with ww_mutex slowpath error injections, we can hit
-ENOMEMs without having actually ran out of memory. We abuse
ww_mutex internals to detect such situations until TTM is fixes
to not convert the error code. In the meantime, injecting
ww_mutex slowpath -EDEADLOCKs is a good way to test
the implementation in the absence of real OOMs.

Just introduce the wrapper in this commit. It will be hooked up
to the driver in following commits.

v2:
- Mark class_xe_validation conditional so that the loop is
skipped on initialization error.
- Argument sanitation (Matt Brost)
- Fix conditional execution of xe_validation_ctx_fini()
(Matt Brost)
- Add a no_block mode for upcoming use in the CPU fault handler.
v4:
- Update kerneldoc. (Xe CI).

drm/xe: Pass down drm_exec context to validation

We want all validation (potential backing store allocation) to be part
of a drm_exec transaction. Therefore add a drm_exec pointer argument
to xe_bo_validate() and ___xe_bo_create_locked(). Upcoming patches
will deal with making all (or nearly all) calls to these functions
part of a drm_exec transaction. In the meantime, define special values
of the drm_exec pointer:

XE_VALIDATION_UNIMPLEMENTED: Implementation of the drm_exec transaction
has not been done yet.
XE_VALIDATION_UNSUPPORTED: Some Middle-layers (dma-buf) doesn't allow
the drm_exec context to be passed down to map_attachment where
validation takes place.
XE_VALIDATION_OPT_OUT: May be used only for kunit tests where exhaustive
eviction isn't crucial and the ROI of converting those is very
small.

For XE_VALIDATION_UNIMPLEMENTED and XE_VALIDATION_OPT_OUT there is also
a lockdep check that a drm_exec transaction can indeed start at the
location where the macro is expanded. This is to encourage
developers to take this into consideration early in the code
development process.

v2:
- Fix xe_vm_set_validation_exec() imbalance. Add an assert that
hopefully catches future instances of this (Matt Brost)
v3:
- Extend to psmi_alloc_object
