[PATCH] ppc64: fix for kexec boot issue
The kexec boot is not successful on some power machines since all CPUs are
getting removed from global interrupt queue (GIQ) before kexec boot. Some
systems always expect at least one CPU in GIQ. Hence, this patch will make
sure that only secondary CPUs are removed from GIQ.
