From 97f9f9763a7a431e04f0ffd4e62d0d288a59f908 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 15 Jun 2018 13:08:34 +0200 Subject: MIPS: Octeon: refactor swiotlb code Share a common set of swiotlb operations, and to instead branch out in __phys_to_dma/__dma_to_phys for the PCI vs non-PCI case. Also use const structures for the PCI methods so that attackers can't use them as exploit vectors.
