Linus,
Please do
git pull \
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git merge
to get another batch of bug-fixes for powerpc. I have included the
full log messages this time. The changes for spu_base.c and
spu_manage.c are mostly code movement that was needed so that a
PS3-only config would build, so the real change isn't as large as the
diffstat might seem to indicate.
Thanks,
Paul.

[POWERPC] Fix size check for hugetlbfs
My "slices" address space management code that was added in the 2.6.22
implementation of get_unmapped_area() doesn't properly check that the
size is a multiple of the requested page size. This allows userland to
create VMAs that aren't a multiple of the huge page size with hugetlbfs
(since hugetlbfs entirely relies on get_unmapped_area() to do that
checking) which leads to a kernel BUG() when such areas are torn down.

[POWERPC] Fix initialization and usage of dma_mask
powerpc has a couple of bugs in the usage of dma_masks that tend to
break when drivers explicitly try to set a 32-bit mask for example.
First, the code that generates the pci devices from the OF device-tree
doesn't initialize the mask properly, then our implementation of
set_dma_mask() was trying to validate the -previous- mask value, not the
one passed in as an argument.
This fixes these problems.

[POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms
with QE UEC"
This reverts commit 3baee955953957be5496cd28e9c544d9db214262.
That commit was a mistake from the start; I added mdio type to the
bus scan list early on in my ucc_geth migrate to phylib development,
which is just pure wrong (the ucc_geth_mii driver creates the mii
bus and the PHY layer handles PHY enumeration without translation).
This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb:
Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"
which was basically trying to hide a symptom of the original mistake
this revert fixes.

[POWERPC] PS3: Fix storage probe logic
Fix the PS3 storage probe logic to properly find device regions on cold
startup.
o Change the storage probe event mask from notify_device_ready
to notify_region_update.
o Improve the storage probe error handling.
o Change ps3_storage_wait_for_device() to use a temporary variable to hold
the buffer address.

[POWERPC] cell: Move SPU affinity init to spu_management_of_ops
This patch moves affinity initialization code from spu_base.c to a
new spu_management_of_ops function (init_affinity), which is empty
in the case of PS3. This fixes a linking problem that was happening
when compiling for PS3.
Also, some small code style changes were made.

[POWERPC] Fix potential duplicate entry in SLB shadow buffer
We were getting a duplicate entry in the SLB shadow buffer in
slb_flush_and_rebolt() if the kernel stack was in the same segment
as PAGE_OFFSET, which on POWER6 causes the hypervisor to terminate
the partition with an error. This fixes it.
Also we were not creating an SLB entry (or an SLB shadow buffer
entry) for the kernel stack on secondary CPUs when starting the
CPU. This isn't a major problem, since an appropriate entry will
be created on demand, but this fixes that also for consistency.
