The patch titled Subject: include/linux/memory.h: drop fields 'hw' and 'phys_callback' from struct memory_block has been removed from the -mm tree. Its filename was mm-drop-elements-hw-and-phys_callback-from-struct-memory_block.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Anshuman Khandual <anshuman.khandual@xxxxxxx> Subject: include/linux/memory.h: drop fields 'hw' and 'phys_callback' from struct memory_block memory_block structure elements 'hw' and 'phys_callback' are not getting used.
