I suggest that we should for the moment revert
3be98be4e9f5  migration: calculate vCPU blocktime on dst side
5f32dc8ee073  migration: add blocktime calculation into migration-test
ca6011c23291  migration: add postcopy total blocktime into query-migrate

unless there is an imminent fix for the ppc32 issues (which seems
unlikely since the code is fundamentally assuming it can atomically
do operations which can't be done atomically on all hosts).

I haven't yet tested that combination of reverts, I'm guessing
at which subsequent commits depend on 3be98be4e9f5. Let me know
if you have suggestions for additions/removals from the revert list.

thanks
