tyan s8226: change lapic of lapic_cluster 0 to 0x30
amd family15 cpu has a lapic_cluster which is the same level with pci domain. Now, the lapic is 0x20 which is already taken by CPU. there are two CPUs on s8226 and each CPU has 8 cores. CPU 0 takes lapic from 0x10 to 0x17 and CPU 1 takes from 0x20 to 0x27.
Now, the dmesg complains as follow: do_IRQ: 1.55 No irq handler for vector (irq -1)
so I change lapic of lapic_cluster to 0x30. although I am not sure what's the exactly meaning of lapic_cluster, this is a workaround to solve this issue.
