Hi, This series does two major things. First is to change how our feature fixup code works, and second is to reorganise exception vectors for pseries, and that requires the first.
This has not had a huge amount of testing. In particular endian, cross compiling, embedded, etc. At this point I want to get something out for comments because it's become quite a large change. To that end, it applies to quite an old -linus revision: d325ea859490511322d1f151dc38577ee9a7c6da Rebasing takes a bit of work, but I'll bring it up to date if the response is positive.
