The intvec handler stores the caches ee in a local variable for use in

not, the intvec handler is using the cached version, when it should be
using the current ee read from the device. Currently, the device
could
be in the PBL ee as the result of a fatal error, but the cached ee
might
be AMSS, which would cause the intvec handler to incorrectly signal a
non-fatal syserr.

This was being fixed by my patch series for execution environment.
I should just send the most important of my patches as one line fixers
from now on.
