Yinghai Lu 3b28cf32cc x86, numa: Fix numa_emulation code with memory-less node0 ... This crash happens on a system that does not have RAM on node0. When numa_emulation is compiled in, and: 1. we boot the system without numa=fake... 2. or we boot the system with numa=fake=128 to make emulation fail we will get: [ 0.076025] ------------[ cut here ]------------ [ 0.080004] kernel BUG at arch/x86/mm/numa_64.c:788! [ 0.080004] invalid opcode: 0000 [#1] SMP [...] need to use early_cpu_to_node() directly, because cpu_to_apicid and apicid_to_node will return node0 that is not onlined.
