Oak Zeng 12f4b58a37 drm/xe: Use hmm_range_fault to populate user pages ... This is an effort to unify hmmptr (aka system allocator) and userptr code. hmm_range_fault is used to populate a virtual address range for both hmmptr and userptr, instead of hmmptr using hmm_range_fault and userptr using get_user_pages_fast. This also aligns with AMD gpu driver's behavior. In long term, we plan to put some common helpers in this area to drm layer so it can be re-used by different vendors. -v1 use the function with parameter to confirm whether lock is acquired by the caller or needs to be acquired in hmm_range_fault.
