I still have an account with RMK's patch tracking system, so I went
ahead and put these there so Russell can pick them up:
https://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=9417/1
https://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=9418/1
I think I did it right, though it has been a decade since I last did
this..
Regards,
Jason
