Quick reply - hopefully shouldn't see anything bad. But should
see more bug reports if we are overflowing the kernel stack and silently corrupting stuff
rather than just falling over silently. So there might be more (useful) reports.
At least on x86 most of the problems caught were not overflowing
the stack but drivers calling virt_to_phys on the stack and
using the physical address for DMA. I'd expect arm64 to be
the same.
