powerpc: 'current_set' is now a table of task_struct pointers
The table of pointers 'current_set' has been used for retrieving the stack and current. They used to be thread_info pointers as they were pointing to the stack and current was taken from the 'task' field of the thread_info. Now, the pointers of 'current_set' table are now both pointers to task_struct and pointers to thread_info. As they are used to get current, and the stack pointer is retrieved from current's stack field, this patch changes their type to task_struct, and renames secondary_ti to secondary_current.
