  "message": "virtio: optimize virtio_access_is_big_endian() for little-endian targets\n\nWhen adding cross-endian support, we introduced the TARGET_IS_BIENDIAN macro\nand the virtio_access_is_big_endian() helper to have a branchless fast path\nin the virtio memory accessors for targets that don\u0027t switch endian.\n\nThis was considered as a strong requirement at the time.\n\nNow we have added a runtime check for virtio 1.0, which ruins the benefit\nof the virtio_access_is_big_endian() helper for always little-endian targets.\n\nWith this patch, always little-endian targets stop checking for virtio 1.0,\nsince the result is little-endian in all cases.\n\nReviewed-by: Cornelia Huck \u003ccornelia.huck@de.ibm.com\u003e\nReviewed-by: Laurent Vivier \u003clvivier@redhat.com\u003e\nSigned-off-by: Greg Kurz \u003cgkurz@linux.vnet.ibm.com\u003e\nReviewed-by: Michael S.
