From b3572e361b6b2ac5e724bc4bb932b7774b720b95 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 30 Oct 2008 16:00:59 -0500 Subject: x86/voyager: fix compile breakage caused by dc1e35c6e95e8923cf1d3510438b63c600fee1e2 Impact: build fix on x86/Voyager Given commits like this: | Author: Suresh Siddha | 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.
