ok, this looks like one of the bugs we fixed in the latest x86.git
(freshly released a few minutes ago). Could you please check x86.git#mm
with this tip:
commit cc77c9972685ea84908eff2fe13114160de5d9cb

x86: cpa: rename global_flush_tlb() to cpa_flush_all()
do you still see that crash?

that's a Linus -git problem, the upstream kobject changes - try Greg's
and Yinghai Lu's patch below, does it help?
