This is the first series of the exception model-specific changes. I
intend to keep this same structure for the rest of the exception
models.
== preparation ==
First few patches are cleanups specific to this model. This comes
first because I'm using some of these changes to help validate what
should be removed in the subsequent patches.
== new powerpc_excp function ==
One patch copies the powerpc_excp function as is and renames it to the
exception model in question. Doing this first facilitates spotting
what changed from the _legacy version.
The following patch changes everything that needs to be changed at the
top level (MSR mask, SF, ILE, AIL, SRRs, etc.) and removes exceptions
that are not used by this processor family.
== exceptions cleanup ==
After the new powerpc_excp function has been made specific to that one
exception model, go through every exception removing anything that
does not apply to this model.
