Another trivial user (recently added) for bitmap_weighted_xx() is
xe_pagefault_queue_init() in drivers/gpu/drm/xe/xe_pagefault.c, but
it's again the Intel's driver, so it will go with your tree anyways.
 
I'm not aware of others, so I believe Tony's tree is the best route.

Attaching a patch for xe_pagefault_queue_init(). Feel free to append it
to this series, or let me know if it's better to send it separately.

Thanks,
