I released 4.2.0-rc1 to the dev tree on kernel.org. I didn't update
the tree on oss.sgi.com or make an official release tarball because
it's a developer pre-release. And there's a couple of things under
discussion that that might require a rebase of the tree, so that's
another reason for not making an "official" release.

Ok, that clears up the confusion. Thanks for explaining what is
happening to the dummy in the audience (me).

No idea - that's definitely a distro issue ;)

This is what I found about an hour before reading this email. On
#xfs:

[06/08/15 09:32] <dchinner_> now that "last modified <$timestamp>" is important
[06/08/15 09:33] <dchinner_> because that tells us what version was used to generate the script
[06/08/15 09:34] <dchinner_> in the version shipped in the 3.2.4 tarball, it is:
[06/08/15 09:34] <dchinner_> timestamp='2014-03-23'
[06/08/15 09:34] <dchinner_> and it clearly has entries for ppc64le in it

That hunk shows why it is failing - no ppc64le:Linux match in the
old script. Nathan is already looking into it...

Cheers,

Dave.
