Subject: powerpc: make OF interrupt tree parsing more strict
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
This patch fixes a bit of boundchecking in the new Open Firmware interrupt
tree parsing code. It's important that it fails when things aren't correct in
order to trigger fallback mecanisms that are necessary to make some machines
work properly.
