David, are there any major M7 patches remaining for basic
functionality?


There is one more patch I am working on that would be part of basic functionality. M7 introduces the register MCDPER which determines whether a precise or a disrupting exception will be delivered to a task when it encounters MCD error. This should be a per task value and hence will need to become part of task context (thread info flags maybe). I am working on code to save and restore this register on context switches, and propagate it on task dup.
