This code is still out of date w/other board ports.  Have you tried
building this against upstream??
=20

I build with powerpc.git.=20
do you mean build with upstream code base ??
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

I mean if you use my 'next' branch of galak/powerpc.git and apply this =
patch, and enable it.  For example MPIC_BROKEN_FRR_NIRQS doesn't exist =
anymore
