We want to use intel_engine_mask_t inside i915_request.h, which means extracting it from the general header file mess and placing it inside a types.h. A knock on effect is that the compiler wants to warn about type-contraction of ALL_ENGINES into intel_engine_maskt_t, so prepare for the worst. v2: Use intel_engine_mask_t consistently v3: Move I915_NUM_ENGINES to its natural home at the end of the enum Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190401162641.10963-1-chris@chris-wilson.co.uk Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
