All we need are a pages array, pin_user_pages_fast can give us that directly. Plus this avoids the entire raw pfn side of get_vaddr_frames. Note that pin_user_pages_fast is a safe replacement despite the seeming lack of checking for vma->vm_flasg & (VM_IO | VM_PFNMAP). Such ptes are marked with pte_mkspecial (which pup_fast rejects in the fastpath), and only architectures supporting that support the pin_user_pages_fast fastpath.
