Yeah, that's Linaro not Stephen.

Yeah, that's not surprising. :(  Neither KVM nor I weren't CC'd on 
either the report or the bugfix; and the perf tree didn't have the code 
at all as Ingo pointed out 
(https://lore.kernel.org/all/ZzxDvLKGz1ouWzgX@gmail.com/).  Anup was 
CC'd on the bugfix but he must have missed too and didn't notify me.
