Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. The tests are back to virtio_finalize_features. No more argument for the architecture callback which only reports if the architecture needs guest memory access restrictions for VIRTIO. I renamed the callback to arch_has_restricted_virtio_memory_access, and the config option to

Hi, Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at kernel.org/ 1. Constify also ioreadX_rep() and mmio_insX(), 2. Squash lib+alpha+powerpc+parisc+sh into one patch for bisectability, 3. Add acks and reviews, 4. Re-order patches so all optional driver changes are at the end. Description =========== The ioread8/16/32() and others have

Hi, Multiple architectures are affected in the first patch and all further patches depend on the first. Maybe this could go in through Andrew Morton's tree? Changes since v2 ================ 1. Drop all non-essential patches (cleanups), 2. Update also drivers/sh/clk/cpg.c . Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at
