[IA64] - SGI SN hwperf enhancements -
Add a new exported function for determining the nearest node with CPUs for I/O nodes and fix a bug where the hwperf dynamic misc device was being registered before misc_init(). Signed-off-by: Mark Goodwin <markgw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
