Change 127558 by zec@zec_tpx32 on 2007/10/15 16:37:30

	Allow for sysctl access to per-vcpu variables.  Most probably
	we won't be virtualizing any existing variables but only
	introducing new state there.  NB I wasn't at school when pointer
	arithmetic was taught so this quick kludge needs to be
	revisited and fixed, along a few other places where I do
	nasty and probably non-portable hacks with pointers.  XXX.
