[PATCH 0/5] Preliminary Exception Manager Work

[Kinsey Moore]

This patch set contains the result of the Exception Manager work I
proposed a while back to manage handling of machine exceptions along
with a general feature for mapping exceptions to POSIX signals without
delving into the CPU Port-specific details. This is a pretty basic
initial implementation, but it can easily be expanded with mutators for
the CPU_Exception_frame for additional capabilities. Also included is a
test that demonstrates usage of the Exception Manager and exception to
signal mapping functionality.
