Arnd Bergmann ebcff9daca vduse: avoid adding implicit padding ... The vduse_iova_range_v2 and vduse_iotlb_entry_v2 structures are both defined in a way that adds implicit padding and is incompatible between i386 and x86_64 userspace because of the different structure alignment requirements. Building the header with -Wpadded shows these new warnings: vduse.h:305:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded] vduse.h:374:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded] Change the amount of padding in these two structures to align them to 64 bit words and avoid those problems. Since the v1 vduse_iotlb_entry already has an inconsistent size, do not attempt to reuse the structure but rather list the members indiviudally, with a fixed amount of padding.
