Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.12-20180410' into staging
ppc patch queue 2018-04-10
Here's a rather late pull request with a handful of fixes for 2.12.
These have been blocked for some time, because I wasn't able to
complete my usual test set due to the SCSI problem fixed in 37c5174
"scsi-disk: Don't enlarge min_io_size to max_io_size".
Since we're in hard freeze, these are all bugfixes. Most are also
regressions, although in one case it's only a "regression" because a
longstanding bug has been exposed by a new machine type (sam460ex) in
the testcases. There are also a couple of sam460ex fixes that aren't
regressions since the board didn't exist before. On the flipside
though, they're low risk because they only touch board specific code
for a board that doesn't exist in any released version.
