* x86: clean up non-smp usage of cpu mapsMike Travis2008-04-171-4/+11
| | | | | | | | | | Cleanup references to the early cpu maps for the non-SMP configuration and remove some functions called for SMP configurations only.

* x86: change size of node ids from u8 to s16travis@sgi.com2008-01-301-5/+5
| | | | | | | | | | | | | | Change the size of node ids for X86_64 from u8 to s16 to accomodate more than 32k nodes and allow for NUMA_NO_NODE (-1) to be sign extended to int.

* x86: fix early cpu_to_node panic from nr_free_zone_pagesMike Travis2008-01-301-0/+2
| | | | | | | | | | | | | | | | | | call early_cpu_to_node() since per_cpu(cpu_to_node_map) might not be setup yet. I also had to export x86_cpu_to_node_map_early_ptr because of some calls from the network code to numa_node_id(): net/ipv4/netfilter/arp_tables.c: net/ipv4/netfilter/ip_tables.c: net/ipv4/netfilter/ip_tables.c: Signed-off-by: Mike Travis <travis@sgi.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* x86: change NR_CPUS arrays in numa_64 fixuptravis@sgi.com2008-01-301-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the following static arrays sized by NR_CPUS to per_cpu data variables: char cpu_to_node_map[NR_CPUS]; fixup: - Split cpu_to_node function into "early" and "late" versions so that x86_cpu_to_node_map_early_ptr is not EXPORT'ed and the cpu_to_node inline function is more streamlined. - This also involves setting up the percpu maps as early as possible. - Fix X86_32 NUMA build errors that previous version of this patch caused. V2->V3: - add early_cpu_to_node function to keep cpu_to_node efficient - move and rename smp_set_apicids() to setup_percpu_maps() - call setup_percpu_maps() as early as possible V1->V2: - Removed extraneous casts - Fix !NUMA builds with '#ifdef CONFIG_NUMA" Signed-off-by: Mike Travis <travis@sgi.com> Reviewed-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
