This.. as presented it is an absolutely unreviewable pile of junk. It
presents code witout any coherent problem description and analysis.
And
the patches are not split sanely either.

There is a more complete and slightly outdated description in the
previous version of the patch at

Not the point, you're mixing far too many things in one go. You also
have the patches split like 'generic / arch-1 / arch-2' which is wrong
per definition, as patches should be split per change and not care about
sily boundaries.

Also, if you want generic entry code, there's patches for that here:
