No, no more stabbing in the dark and no more brown paper bags.
Please check whether CPUID(4) works that early in any xen guest and
let's add that check to a function which does something like:
bool loader_disabled(void)
{
if (running_on_a_xen_guest)
return true;
if (check_loader_disabled_bsp())
return true;
if (!have_cpuid_p())
return true;
return false;
}
and call that at the entry points and be done with it.
Or if there's some other clean method to detect I'm running on a xen
guest.
Thanks.
