d0e132b536 [PATCH] powerpc: Loosen udbg_probe_uart_speed sanity checking
The checking of the baudrate in udbg_probe_uart_speed was
too tight and would cause reporting back of the default
baud rate in cases where the computed speed was valid.

b226e46212 [PATCH] powerpc: don't add memory to empty node/zone
The system will oops if an attempt is made to add memory to an
empty node/zone.  This patch prevents adding memory to an empty
node.  The code to dynamically add a node/zone is non-trivial.
This patch is temporary and will be removed when the ability
to dynamically add a node/zone is complete.

14c89e7fc8 [PATCH] powerpc: Replace VMALLOCBASE with VMALLOC_START
On ppc64, we independently define VMALLOCBASE and VMALLOC_START to be
the same thing: the start of the vmalloc() area at 0xd000000000000000.
VMALLOC_START is used much more widely, including in generic code, so
this patch gets rid of the extraneous VMALLOCBASE.

This does require moving the definitions of region IDs from page_64.h
to pgtable.h, but they don't clearly belong in the former rather than
the latter, anyway.  While we're moving them, clean up the definitions
of the REGION_IDs:
	- Abolish REGION_SIZE, it was only used once, to define
REGION_MASK anyway
	- Define the specific region ids in terms of the REGION_ID()
macro.
	- Define KERNEL_REGION_ID in terms of PAGE_OFFSET rather than
KERNELBASE.  It amounts to the same thing, but conceptually this is
about the region of the linear mapping (which starts at PAGE_OFFSET)
rather than of the kernel text itself (which is at KERNELBASE).

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.

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.

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.

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.

   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.

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.

51fae6de24 [PATCH] powerpc: Add a is_kernel_addr() macro
There's a bunch of code that compares an address with KERNELBASE to see if
it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to
compare with PAGE_OFFSET, since we're going to change KERNELBASE soon.

So replace all of them with an is_kernel_addr() macro that does that.

cd0ca2ce4b [PATCH] powerpc: Propagate regs through to machine_crash_shutdown
Currently machine_crash_shutdown() gets a struct pt_regs, but doesn't pass it
through to the ppc_md function, it should.

e40c7f0272 [PATCH] powerpc32: fix definition of distribute_irqs
When we select ppc32 under the powerpc architecture we get the
error below.  This relates to defining distribute_irqs when this
configuratiom option is undefined.

9100b205fd [PATCH] powerpc32: clean up available memory models
Clean up the currently available memory models for ppc32 under
the powerpc architecture.  We need FLATMEM for ppc32: enable it.
SPARSEMEM is not parameterised for ppc32 so disable that.  Take this
opportunity to clean up white space for FLATMEM_ENABLE.
