Could you explain what difference you think it makes ... because I can't
really see one.

All the patch seems to be doing is setting r1 to the stack pointer with
interrupts enabled and then copying the value with interrupts disabled,
which is fine, but I don't see how it's different from setting r30
directly from the task entry within the interrupt disabled region.
