[Xen-merge] [PATCH] allow x86-64/SMP to boot

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

Since x86-64 general code changes were merged a little carelessly into
xen specific code, SMP kernels didn't boot anymore, because
cpu_possible_map is required to be properly filled much earlier.
Attached a patch that allowed us to get things to work again, but I'm
not certain this is entirely the right change; namely am I unsure what
set of processors the hypervisor makes available through ACPI (the
vcpu-s the domain is configured for, which would imply ACPI tables
different from the BIOSes get provided, or the raw CPUs available on the
system, in case the original ACPI tables get mirrored to the domain).
