Hi Dave,

it doesn't compile for me when CONFIG_SMP is set:

It's the following part of the -dj1 patch (I've skipped the rest of the
sched.c changes):

The problem seems to be that "bind_cpu" is renamed to "unused" but it is
used two lines later.

[PATCH] 2.5.9-dj1 bind_cpu compile error

[Adam Kropelin]

It looks like a piece of Erich Focht's migration thread patch escaped
2.5.9-dj1. This fixes it for me...
