From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx> Subject: mm/memblock.c: replace u64 with phys_addr_t where appropriate Most functions in memblock already use phys_addr_t to represent a physical address with __memblock_free_late() being an exception. This patch replaces u64 with phys_addr_t in __memblock_free_late() and switches several format strings from %llx to %pa to avoid casting from phys_addr_t to u64.
