[ARM] 3927/1: Allow show_mem() to work with holes in memory map.
show_mem() was not correctly handling holes in the memory map. It was treating the freed sections of the map as though they contained valid struct page entries. This could cause incorrect debugging output or even a kernel panic. This patch keeps the struct meminfo around after system initialization so that show_mem() can use it when scanning memory. show_mem() now walks over each bank of each online node, rather than assuming that each node contains a single contiguous bank.
