Automatic NUMA balancing currently depends on reusing the PROT_NONE bit which has caused problems on Xen. In preparation for using one of the unused physical address bits this patch requires x86-64 for automatic NUMA balancing. 32-bit support for NUMA on x86 is no longer interesting and the loss of automatic NUMA balancing support should be no surprise.
