It would be lovely if you can bisect a bit. But my merges in that
range are all from Ingo:

Ingo Molnar (7):
    header cleanup
    objtool updates
    RCU updates
    EFI updates
    locking updates
    perf updates
    scheduler updates

but not having any messages at all makes it hard to guess where it would be.

A few bisect runs would narrow it down a fair amount. Bisecting all
the way would be even better, of course,
