Now we get this map layout by call XENMEM_memory_map then save them into one global variable memory_map[]. It should include lowmem range, rdm range and highmem range. Note rdm range and highmem range may not exist in some cases. And here we need to check if any reserved memory conflicts with [RESERVED_MEMORY_DYNAMIC_START, RESERVED_MEMORY_DYNAMIC_END). This range is used to allocate memory in hvmloder level, and we would lead hvmloader failed in case of conflict since its another rare possibility in real world.
