This is an issue because these allocations are done before reserved memory regions are set aside in arch_mem_init(). This means that there is a possibility for memblock to allocate memory from any of the reserved memory regions. Hence, move the call to arch_mem_init() to be earlier in the init sequence so that all reserved memory is set aside before any allocations are made with memblock.
