2007-02-20[PATCH] slab: reduce size of alien cache to cover only possible nodesChristoph Lameter2-2/+2
The alien cache is a per cpu per node array allocated for every slab on the system. Currently we size this array for all nodes that the kernel does support. For IA64 this is 1024 nodes. So we allocate an array with 1024 objects even if we only boot a system with 4 nodes. This patch uses "nr_node_ids" to determine the number of possible nodes supported by a hardware configuration and only allocates an alien cache sized for possible nodes. The initialization of nr_node_ids occurred too late relative to the bootstrap of the slab allocator and so I moved the setup_nr_node_ids() into free_area_init_nodes().

2007-02-20[PATCH] Convert highest_possible_processor_id to nr_cpu_idsChristoph Lameter5-29/+17
We frequently need the maximum number of possible processors in order to allocate arrays for all processors. So far this was done using highest_possible_processor_id(). However, we do need the number of processors not the highest id. Moreover the number was so far dynamically calculated on each invokation. The number of possible processors does not change when the system is running. We can therefore calculate that number once.

2007-02-20[PATCH] Replace highest_possible_node_id() with nr_node_idsChristoph Lameter3-18/+25
highest_possible_node_id() is currently used to calculate the last possible node idso that the network subsystem can figure out how to size per node arrays. I think having the ability to determine the maximum amount of nodes in a system at runtime is useful but then we should name this entry correspondingly, it should return the number of node_ids, and the the value needs to be setup only once on bootup. The node_possible_map does not change after bootup. This patch introduces nr_node_ids and replaces the use of highest_possible_node_id(). nr_node_ids is calculated on bootup when the page allocators pagesets are initialized.

This patch provides code paths which allow the natsemi driver to use the external MII port on the chip but ignore any PHYs that may be attached to it. The link state will be left as it was when the driver started and can be configured via ethtool. Any PHYs that are present can be accessed via the MII ioctl()s. This is useful for systems where the device is connected without a PHY or where either information or actions outside the scope of the driver are required in order to use the PHYs.
