  Thanks for confirming that -- for the time being I've unforwarded
this bug from upstream issue #553 as it looks like this is a new
problem.

  Can you grab /proc/cpuinfo from a physical CI host as well as from
within a container for the armel, armhf, and arm64 architectures? That
will let us see what difference(s) lxcfs is presenting and might give a
clue for the root issue. Since only the 32bit arm architectures appear
to be affected, I'm also curious to see what the arm64 cpuinfo is.
