Subject[PATCH] mesh: target 0 aborted
From
Date
This patch makes mesh.c compile, by adapting it to the new
pmac_feature API (ported from the ppc tree).

In addition it contains the fix from Thomas Capricelli for the
infamous "mesh: target 0 aborted" error, which I've been personally
observing since 2.1.13x.

Regards,
-velco
