Some ww utilities mainly for the accompanying selftests added by Thomas, as well as modified the above patches for ww locking- and lmem support. The actual hook up to the i915 ttm backend is being worked on and not included yet, so this is considered to be an early review opportunity. v2: - A couple of minor style fixes pointed out by Matthew Auld - Export and use intel_engine_destroy_pinned_context() to address a CI warning / failure.
