Hi Ingo,

Thanks for this.  The concept is certainly good.

The patch that adds a new architecture to all these files would give 
us a good overview about how complete an initial port is.

If you want to test how hard that is (and what sort of patch it
produces), the h8300 architecture was added to linux-next recently.

I tried this out, this is the resulting feature support matrix for the 
new h8300 architecture:
