it broke 4 sockets quad core above with 64 bit

Booting processor 11/15 ip 6000
Initializing CPU#11
masked ExtINT on CPU#11
Calibrating delay using timer specific routine.. 4589.46 BogoMIPS (lpj=9178934)
CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
CPU: L2 Cache: 512K (64 bytes/line)
CPU 11/f -> Node 2
CPU: Physical Processor ID: 2
CPU: Processor Core ID: 3
CPU11: Quad-Core AMD Opteron(tm) Processor 8356 stepping 03
checking TSC synchronization [CPU#0 -> CPU#11]: passed.
Booting processor 12/16 ip 6000

looks like local apic id up 4 bit is masked out. so can not start 0x10
above any more.
