Merge tag 'v3.18-rc6' into devicetree/next

v3.18-rc6 contains an important DT bug fix, c1a2086e2d, "of/selftest:
Fix off-by-one error in removal path" which affects testing of the
overlay patch series. Merge it into the devicetree/next staging branch
so that the overlay patches are applied on top of a known working tree.
