As mentioned in the discussion of the cover letter of this series,
we'd really like to move this to fixes for 4.13.

I'd like to move forward on this soon. Can I just do a wholesale
rewrite of the commit message along the lines of the following
example, and move the 3 patches to fixes for 4.13?

arm64: allwinner: a64: bananapi-m64: add missing ethernet0 alias

The EMAC Ethernet controller was enabled, but an accompanying alias
was not added. This results in unstable numbering if other Ethernet
devices, such as a USB dongle, are present. Also, the bootloader uses
the alias to assign a generated stable MAC address to the device node.

Fixes: e7295499903d ("arm64: allwinner: bananapi-m64: Enable dwmac-sun8i")

Thanks
