Just reworked my series, with the following changes:
- patch #2 is dropped entirely (which is good, as it was really making me feel rather uncomfortable)
- patch #3 becomes a bit cleaner (basically a simplified version of the x86 version, with the added feature of a configurable flow handler, see below).

So yes, definitely am improvement.  I'm still a bit worried about the flow handler being set by the top-level domain, which makes it the odd case on ARM (we always set it at the bottom level for all other use cases). It works, but having two different set of rules feels fragile to me.

Anyway, thanks for the heads up!

Thanks,

	M.
