Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170323' into staging
ppc patch queue for 2017-03-23 Just a single bugfix in this batch. It's not strictly in ppc code, though it's for the pseries machine's benefit. Eduardo suggested it go through my tree however. # gpg: Signature made Thu 23 Mar 2017 10:09:17 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170323: numa,spapr: align default numa node memory size to 256MB Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
