I found a small bug of NUMA emulation code for x86_64. (CONFIG_NUMA_EMU) If machine is non-NUMA, find_node_by_addr() should return NUMA_NO_NODE, but current implementation code returns existent maximum NUMA node number + 1. This is not existent NUMA node number. However, this behaviour does not affect NUMA emulation fortunately, because acpi_fake_nodes() that is caller of find_node_by_addr() gets pxm (proximity domain) by node_to_pxm() from non-existent NUMA node number that was returned by find_node_by_addr(). node_to_pxm() returns PXM_INVAL that means illegal or non-existent NUMA node number.
