thread_info is not anymore in the stack, so the entire stack
can now be used.

Nice.

In the meantime, all pointers to the stacks are not anymore
pointers to thread_info so this patch changes them to void*

Wasn't this previously effectively already the case with patch
3/7? You had thread_info sized space left there, but it was not
used or initialized right? Does it make sense to move this part
of it to the previous patch?

Not really.

In 3/7 I changed the prototypes of two functions that really used the 
pointer as a task pointer only.

Here it change things that before 4/7 were really used as both stack 
pointers and thread_info pointers.
