Hi,
We've been struggling to debug a hang on a large ppc64 box. Every time
we collect oops output there are pieces of the oops output missing and
in some cases entire CPUs are missing.

(powerpc/kexec: Remove ppc_md.machine_kexec) on Jan 6th, 2011, which

Unfortunately it looks like it *is* used by the mpc85xx kexec()

higher we risk not having enough RMO memory for the kdump kernel on boxes
with a 128MB RMO.

Hi Josh,
I'd like to run a few tests with this disabled on the 4xx boards first please.
I can't say that all the boards I have will have any sort of distro to begin
with, and if they did they might not be running something from the last 3 or
4 years. I do run -git kernels on them frequently
in the first place.
That can be fixed in a follow up patch.

I'm not sure why we have code for parsing an ibm,smt-snooze-delay OF
property. Since we have a smt-snooze-delay= boot option and we can
also set it at runtime via sysfs, it should be safe to get rid of
this code.

boot it didn't seem worth adding a per node valid bit.

The patch below sets a smaller value for RECLAIM_DISTANCE and thus enables
zone reclaim.
