[Mindaugas Rasiukevicius <rmind%netbsd.org@localhost>]

Module Name:    src
Committed By:   rmind
Date:           Sun Aug  5 01:19:18 UTC 2007

Modified Files:
        src/sys/dev/ieee1394: fw_port.h
        src/sys/kern: kern_cpu.c subr_workqueue.c
        src/sys/sys: cpu.h cpu_data.h param.h

Log Message:
Improve per-CPU support for the workqueue(9):
 - Make structures CPU-cache friendly, as suggested and explained
   by Andrew Doran.  CACHE_LINE_SIZE definition is invented.
 - Use current CPU if NULL is passed to the workqueue_enqueue().
 - Implemented MI CPU index, which could be used as an index of array.
   Removed linked-lists usage for work queues.

The roundup2() function avoids division, but works only with power of 2.
