[PATCH] x86-64: always use physical delivery mode on > 8 CPUs
Remove clustered APIC mode. There's little point in the use of clustered APIC mode, broadcasting is limited to within the cluster only, and chipsets have bugs in this area as well. So default to physical APIC mode when the CPU count is large, and default to logical APIC mode when the CPU count is 8 or smaller. (this patch only removes the use of genapic_cluster and cleans up the resulting genapic.c file - removal of all remaining traces of clustered mode will be done by another patch.)
