> Do you have a PPC64 nptl kernel working?
I'm running a ppc64 kernel on an RS/6000 B80 at the moment, and I just
tried my ppc32 NPTL build, and it passed all the tests. The kernel is
stock 2.5.65 plus the patch below (which adds CLONE_SETTLS support)
plus a couple of other unrelated patches. I haven't tried building a
ppc64 NPTL yet.
