We used to print a NUMA cpu summary at boot before the hotplug cpu code
was added. This has been useful for catching machine configuration as
well as firmware bugs in the past.

This patch restores that functionality. An example of the output is:

Jens.Osterkamp@de.ibm.com 49d65b3ac5 [PATCH] powerpc/cell: add iommu support for larger memory
So far, the iommu code was hardwired to a linear mapping
between 0x20000000 and 0x40000000, so it could only support
512MB of RAM.

This patch still keeps the linear mapping, but looks for
proper ibm,dma-window properties to set up larger windows,
this makes the maximum supported RAM size 2GB.

If there is anything unusual about the dma-window properties,
we fall back to the old behavior.

We also support switching off the iommu completely now
with the regular iommu=off command line option.

Arnd Bergmann 3a843d7cd3 [PATCH] spufs: fix mailbox polling
Handling mailbox interrupts was broken in multiple respects,
the combination of which was hiding the bugs most of the time.

- The ibox interrupt mask was open initially even though there
  are no waiters on a newly created SPU.

- Acknowledging the mailbox interrupt did not work because
  it is level triggered and the mailbox data is never retrieved
  from inside the interrupt handler.

- The interrupt handler delivered interrupts with a disabled
  mask if another interrupt is triggered for the same class
  but a different mask.

- The poll function did not enable the interrupt if it had not
  been enabled, so we might run into the poll timeout if none of
  the other bugs saved us and no signal was delivered.

We probably still have a similar problem with blocking
read/write on mailbox files, but that will result in extra
wakeup in the worst case, not in incorrect behaviour.

Arnd Bergmann 2a911f0bb7 [PATCH] spufs: Improved SPU preemptability [part 2].
This patch reduces lock complexity of SPU scheduler, particularly
for involuntary preemptive switches.  As a result the new code
does a better job of mapping the highest priority tasks to SPUs.

Lock complexity is reduced by using the system default workqueue
to perform involuntary saves.  In this way we avoid nasty lock
ordering problems that the previous code had.  A "minimum timeslice"
for SPU contexts is also introduced.  The intent here is to avoid
thrashing.

While the new scheduler does a better job at prioritization it
still does nothing for fairness.

Arnd Bergmann 5110459f18 [PATCH] spufs: Improved SPU preemptability.
This patch makes it easier to preempt an SPU context by
having the scheduler hold ctx->state_sema for much shorter
periods of time.

As part of this restructuring, the control logic for the "run"
operation is moved from arch/ppc64/kernel/spu_base.c to
fs/spufs/file.c.  Of course the base retains "bottom half"
handlers for class{0,1} irqs.  The new run loop will re-acquire
an SPU if preempted.

Michael Ellerman 758438a7b8 [PATCH] powerpc: Fixups for kernel linked at 32 MB
There's a few places where we need to fix things up for the kernel to work
if it's linked at 32MB:

 - platforms/powermac/smp.c
   To start secondary cpus on pmac we patch the reset vector, which is fine.
   Except if we're above 32MB we don't have enough bits for an absolute branch,
   it needs to relative.
 - kernel/head_64.s
    - A few branches in the cpu hold code need to load the full target address
      and do a bctr.
    - after_prom_start needs to load PHYSICAL_START as the dest address, not 0.
    - The exception prolog needs to load the low word of the target adddress,
      not just the low halfword.
    - Fixup handling of the initial stab address.
 - kernel/setup_64.c
   smp_release_cpus() needs to write 1 to the spinloop flag near 0, not 32 MB.

Michael Ellerman b5666f7039 [PATCH] powerpc: Separate usage of KERNELBASE and PAGE_OFFSET
This patch separates usage of KERNELBASE and PAGE_OFFSET. I haven't
looked at any of the PPC32 code, if we ever want to support Kdump on
PPC we'll have to do another audit, ditto for iSeries.

This patch makes PAGE_OFFSET the constant, it'll always be 0xC * 1
gazillion for 64-bit.

To get a physical address from a virtual one you subtract PAGE_OFFSET,
_not_ KERNELBASE.

KERNELBASE is the virtual address of the start of the kernel, it's
often the same as PAGE_OFFSET, but _might not be_.

If you want to know something's offset from the start of the kernel
you should subtract KERNELBASE.

Linas Vepstas 2bf6a8fa21 [PATCH] powerpc: migrate common PCI hotplug code
23-rpaphp-migrate.patch (parts)

This patch moves some pci device add & remove code from the PCI
hotplug directory to the arch/powerpc/kernel directory, and cleans
it up a tad. The primary reason for this is that the code performs
some fairly generic operations that are shared with the PCI error
recovery code (living in the arch/powerpc/kernel directory).

Linas Vepstas facf07870b [PATCH] powerpc: make pcibios_claim_one_bus available to other code
22-rpaphp-eliminate-dupe-code.patch (parts)

The RPAPHP code contains two routines that appear to be gratuitous
copies of very similar pci code.  In particular,

   rpaphp_claim_resource ~~ pci_claim_resource
   rpadlpar_claim_one_bus == pcibios_claim_one_bus

This makes pcibios_claim_one_bus from arch/powerpc/kernel/pci_64.c
available to the RPAPHP code.

Linas Vepstas e2a296eeaa [PATCH] powerpc: PCI hotplug common code elimination
20-rpaphp-eeh-cleanup.patch

This patch move some code from the rpaphp directory, to the powerpc
directory, where it should have been all along (Among other things, I
need it in the powerpc directory for the PCI error recovery.)

Please note that patch affects TWO maintainers: Paul, after applying
the powerpc part, please ask that GregKH appli the PCI part. It is safe
to have the powerpc part go in first. It would be bad to have the
PCI part go in first.
