Turned out this is actually the ras/core branch from tip tree, esp.

No, it's because the RAS stuff ran into horrible conflicts with the UUID
tree:

https://lkml.org/lkml/2017/6/16/22

Tyler should be rebasing that soon, so hopefully I can requeue that stuff
this week.

any reason why there was a roll back of for-next/core?

 + 0870f692c2ed...e27c7fa015d6 for-next/core -> arm64/for-next/core  (forced 
update)

Is it because for-next/ras-apei goes through tip?

Thanks, I've pushed this out as:

  git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git 
for-next/ras-apei

which I'll merge into for-next/core (and therefore linux-next) either the
end of this week or the beginning of next week. Please take a look if you
get a chance.
