Hey Paul,

Top of your -next tree fails with a stack overflow on the MPC5200 when
attempting to mount an NFS rootfs (log below).  I haven't had a chance
to bisect yet, but I'm posting this in case someone has already seen
and solved this.

Cheers,
g.

MPC5200 is a 603 core right ?

Looks like a brown paper bag for me.

Hi Paul,

Here are a few more for you.  These are all the MPC5200 patches that
I've currently got in my queue and they are based off of your current
-next tree.

The first commit is Ben's fix for the missing blr instruction in
_tlbia() which is critical to get in ASAP.

Thanks,
g.

Yup, that solved it.  Committed into my tree and pushed out for Paulus

[patch 0/2] please pull from cell next branch

[arnd]

Hi Paul,

here are my 2 pending patches I have queued up for 2.6.29, please add
them to your next branch or pull directly from

[patch 1/2] powerpc/cell: fix build breakage with CONFIG_SPUFS disabled

[arnd]

CBE_THERM and OPROFILE_CELL both cannot be built without
SPU_FS disabled, so make the dependency explicit.

[patch 2/2] powerpc/cell: add QPACE as a separate Cell platform

[arnd]

Since the QPACE (Chromodynamics Parallel Computing on the
Cell Broadband Engine) platform doesn't use a iommu, doesn't
have PCI devices and a MPIC much lesser setup and
configurations are needed. So far all devices are detected
as OF device. A notifier function is used to set the dma_ops
for the of_platform bus. Further this patch splits the
PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are
shared with the QPACE platform and the rest.

Thanks a lot! Can you also pick up this one, too. It seems to have
