Follow-ups

 

--- Vivi Li                                                  2010-12-30 22:59:52

Configuration description is changed so CONFIG_KGDB is not selected. Test script

is updated.

Recheck the result later.

 

--- Sonic Zhang                                              2010-12-30 23:04:31

Not a bug. The kgdb test building script need to be updated according to the new

kernel config options.

 

--- Vivi Li                                                  2011-01-04 21:29:25

Fixed and close.
