I haven't bisected this yet, but with the current -git I'm getting
watchdog: BUG: soft lockup - CPU#41 stuck for 49s!
and the common call chain seems to be in flush_tlb_mm_range ->
on_each_cpu_cond_mask.
Commit e058a84bfddc42ba356a2316f2cf1141974625c9 is good, and looking
at the pulls and merges I've done since, this -mm series looks like
the obvious culprit.
I'll go start bisection, but I thought I'd give a heads-up in case
somebody else has seen TLB-flush-related lockups and already figured
out the guilty party..
