I'd like to review this series but it has two technical issues:
- the patches are not in plain text format and so git am is unable to apply them
- the 4th patch of the series didn't make it through the list, I guess
it's too big

I guess the easiest way for me to review this series is if you could point
me to a public git repository with these patches. Alternatively you could
use git send-email to send the patches, split patch 4 into pieces (e.g.
one core per patch) and add me to the cc: list.
