Hmm, not for me. See below.

What setup were you testing on Bharata?

I was on commit a94572f5799dd of userfault21 branch in Andrea's tree
git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git

#uname -a
Linux 4.1.0-rc8+ #1 SMP Tue Aug 11 11:33:50 IST 2015 ppc64le ppc64le ppc64le GNU/Linux

In fact I had successfully done postcopy migration of sPAPR guest with
this setup.

OK, do you mind testing mainline with the same setup to see if the selftest
passes.

Ah, I just tried it on big endian and it works. So it seems to not work on
little endian for some reason, /probably/ a test case bug?

cheers
