[PATCH] Increase max kmalloc size for very large systems



Systems with extemely large numbers of nodes or cpus need to kmalloc
structures larger than is currently supported.  This patch increases the
maximum supported size for very large systems.

This patch should have no effect on current systems.

(akpm: why not just use alloc_pages() for sysfs_cpus?)
