Change 100600 by jb@jb_freebsd2 on 2006/07/05 02:45:17

	Revise the size of the padding to reflect the additional fields
	in the machine independent part of the pcpu structure for 
	DTrace.
	
	Note: This padding will break if KTR_PERCPU is defined on sun4v
	because that adds variables to the pcpu structure that don't
	add up to a multiple of 64 bytes as expected by sun4v/machdep.c.
