The patch looks simple but please explain why you do what you do.
It took me some digging before I could convince mysleft this was
indeed a correct change.
And I am pretty sure you did the same investigation yourself.
A comment like:
arch/x866/kernel/inittask.c require all variables allocated in
the section .data.init_task to be aligned with THREAD_SIZE.
would have made me happy.
