H A D | setup.c | dd4f0888 Mon Jun 30 17:03:14 CDT 2008 Tony Luck <tony.luck@intel.com> [IA64] Bugfix for system with 32 cpus
On a system where there are no hot pluggable cpus "additional_cpus" is still set to -1 at the point where we call per_cpu_scan_finalize(). If we didn't find an SRAT table and so pick the default "32" for the number of cpus, when we get to: high_cpu = min(high_cpu + reserve_cpus, NR_CPUS); we will end up initializing for just 31 cpus ... and so we will die horribly when bringing up cpu#32.
Problem introduced by: 2c6e6db41f01b6b4eb98809350827c9678996698 "Minimize per_cpu reservations."
