Change 131295 by jb at jb_freebsd1 on 2007/12/20 06:54:13

	Choose to typedef struct pcpu as pcpu_t rather than cpu_t so
	that cpu_t can be redefined depening on what we're try to
	provide compatibility for.
	
	There is a case where the OpenSolaris cyclic timer device uses
	fields in struct pcpu (or their equivalent), but I don't want
	to soil our pcpu with stuff to make it all opaque to get around
	the CDDL. Instead I'll just give the cyclic timer device a
	cpu array of it's own and it turns out I want to refer to that
	with a cpu_t.
	
	(or something like that)
