Patches 1-6 remain the same as the previous post. Patch 7 was heavily changed according to MST's comments. --- Greg Kurz (7): virtio: introduce virtio_is_little_endian() helper tun: add tun_is_little_endian() helper macvtap: introduce macvtap_is_little_endian() helper vringh: introduce vringh_is_little_endian() helper vhost: introduce vhost_is_little_endian() helper virtio: add explicit big-endian support to memory accessors vhost: feature to set the vring endianness drivers/net/macvtap.c | 11 ++++++-- drivers/net/tun.c | 11 ++++++-- drivers/vhost/Kconfig | 10 +++++++ drivers/vhost/vhost.c | 55 ++++++++++++++++++++++++++++++++++++++ drivers/vhost/vhost.h | 34 +++++++++++++++++++---- include/linux/virtio_byteorder.h | 24 ++++++++++------- include/linux/virtio_config.h | 19 +++++++++---- include/linux/vringh.h | 19 +++++++++---- include/uapi/linux/vhost.h | 5 +++ 9 files changed, 156 insertions(+), 32 deletions(-) -- Greg -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
