More precisely, it allows the guest drivers to pick the endianness they
prefer.  Mixed-endian virtio works fine on QEMU with e.g. a mips guest
in emulation mode, because then any given QEMU binary will always use
the same endianness (e.g. big for qemu-system-mips).

As far as I understand, patches 2 and 3 are really separate bugfixes,
and they should go in irrespective of patch 1.
