It is no problem that you picked these up for testing. But don't merge them yet, please.
Suresh's underlying problem with the unnecessary sched domains is a failing of sched-balance-exec and sched-balance-fork, which I am working on now.
Removing unnecessary domains is a nice optimisation, but just needs to account for a few more flags before declaring that a domain is unnecessary (not to mention this probably breaks if isolcpus= is used). I have made some modifications to the patch to fix these problems.
Lastly, I'd like to be a bit less intrusive with pinned task handling improvements. I think we can do this while still being effective in preventing livelocks.
I will keep you posted with regards to the various scheduler patches.
