[matthew green <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg
Date:           Wed Jan 13 01:57:17 UTC 2010

Modified Files:
        src/sys/kern: kern_cpu.c kern_runq.c
        src/sys/sys: cpu.h cpu_data.h

Log Message:
introduce a new function that returns a unique string for each cpu:

        char *cpu_name(struct cpu_info *);

and use it when setting up the runq event counters, avoiding an 8 byte
kmem(4) allocation for each cpu.  there are more places the cpuname is
used that can be converted to using this new interface, but that can
and will be done as future work.

as discussed with rmind.
