Ben writes: This goto should not have been changed, as no DMA mapping has been attempted at this point in the function. This seems to have been fixed upstream by commit 6a885b60dad2 "liquidio: Introduce new octeon2/3 header". I leave it to you to work out how it should be fixed in 4.4-stable. Fix this up by hand, as the referenced patch isn't worthy of being backported. Reported-by: Ben Hutchings Cc: Florian Fainelli Cc: David S.
