has been removed from the -mm tree. Its filename is
uml-dont-roll-my-own-random-mac-generator.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: uml: don't roll my own random MAC generator
From: Jeff Dike <jdike@xxxxxxxxxxx>
Use the existing random_ether_addr() instead of cooking up my own
version. Pointed out by Dave Hollis and Jason Lunz.
