Comment 1 for bug 942659

This change changes the behaviour for non-M-profile cores, which looks wrong.

See discussion in this mailing list thread where a similar patch was suggested:

M profile interrupt handling is known-broken. I'm not accepting any patches in this area unless they come attached to a decent explanation of why they are the correct change to make and show some evidence of the whole problem having been considered.
