This patch does the following: - creates a cacheline aligned/padded struct cpu_stat[NR_CPUS]. - moves the [NR_CPUS] members of kernel_stat into cpu_stat This moves the stat data that a cpu will update into a contiguous region. Previous users of kernel_stat would compete for an array's cacheline with other cpus. - creates /proc/cpu/[0-9]+/ and fs/proc/proc_cpu.c with code for managing files in the cpu's directories. This should be useful for rusty's */active and arjan/rmk's */frequency. I have no strong feelings about where this lives or what it should be named. - adds collection of fault statistics and adds 'context migration' recording, per cpu. - updates users of kernel_stat in proc, reports shouldn't change - updates every friggin' user of kstat.irqs[] in arch/ with a macro so that we never have to do this again. The patch is rather large, due to that last bit.
