x86/voyager: fix compile breakage caused by dc1e35c6e95e8923cf1d3510438b63c600fee1e2
Impact: build fix on x86/Voyager Given commits like this: | Author: Suresh Siddha <suresh.b.siddha@intel.com> | Date: Tue Jul 29 10:29:19 2008 -0700 | | x86, xsave: enable xsave/xrstor on cpus with xsave support Which deliberately expose boot cpu dependence to pieces of the system, I think it's time to explicitly have a variable for it to prevent this continual misassumption that the boot CPU is zero.
