Ingo Molnar 54ffaa45c5 x86: fix CONFIG_NUMA and nosmp | maxcpus=0/1 crash ... x86 NUMA kernels crash in the scheduler setup code if "nosmp" or "maxcpus=0" is passed on the boot command line: | Brought up 1 CPUs | BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 | printing eip: c011f0b5 *pde = 00000000 | Oops: 0000 [#1] SMP | | Pid: 1, comm: swapper Not tainted (2.6.23 #67) | EIP: 0060:[<c011f0b5>] EFLAGS: 00010246 CPU: 0 | EIP is at sd_degenerate+0x35/0x40 the reason is sloppy spaghetti code in smpboot_32.c that resulted in a missing map_cpu_to_logical_apicid() call - which also had the side-effect of setting up the cpu_2_node[] entry for the lone CPU. That resulted in node_to_cpumask(0) resulting in 00000000 - confusing the sched-domains setup code.
