The patch titled
lib-do-code-optimization-for-radix_tree_lookup-and-radix_tree_lookup_slot update
has been removed from the -mm tree. Its filename was
lib-do-code-optimization-for-radix_tree_lookup-and-radix_tree_lookup_slot-update.patch
This patch was dropped because it was folded into lib-do-code-optimization-for-radix_tree_lookup-and-radix_tree_lookup_slot.patch
