Miller" List-ID: Rather than use the memblock_alloc_base that returns a physical address and then convert this address to the virtual one, use appropriate memblock function that returns a virtual address. There is a small functional change in the allocation of then NODE_DATA(). Instead of panicing if the local allocation failed, the non-local allocation attempt will be made.
