I found the config for 561 smp kernel is wrong. Update build_policy_kernel.exp

to fix this.

 

--- Vivi Li                                                  2011-01-24 22:27:28

Configuration is OK now. But it will still crash.

 

--- steven miao                                              2011-01-31 05:27:53

percpu data is unaligned caused this crash. tuning PERCPU(PAGE_SIZE) definition

in vmlinux.lds.S link script can resolve this unalignment.

 

--- Vivi Li                                                  2011-05-30 05:59:20

OK. Close it.
