From: Mike Rapoport <rppt****@linux*****> for_each_memblock() is used exclusively to iterate over memblock.memory in a few places that use data from memblock_region rather than the memory ranges. Remove type parameter from the for_each_memblock() iterator to improve encapsulation of memblock internals from its users.
