While working on the conversion of the s390 port to use memblock and nobootmem instead of bootmem I discovered two small bugs: alloc_memory_core_early() in mm/nobootmem.c called memblock_reserve() without forwarding the return value of memblock_reserve(). free_low_memory_core() (used by free_all_bootmem) in mm/nobootmem.c already took care of releasing the memblock.reserved array in case it has been allocated using memblock itself. This behaviour was missing for memblock.memory. Cases where memblock.memory grows bigger than the initial 128 entries have been seen. So this should be supported as well.
