Re: more thread_info patches

Hi,

This globally replaces the access to the thread_info field in task_struct
with either:
- direct access of the stack field, where it's obvious it wants the stack
- the same for end_of_stack()
- everything else with task_thread_info()

To simplify merging anything anything that creates conflicts can simply be
dropped and can be dealt with latter.

bye, Roman
