Subject: [SBUS]: Start cleaning up generic sbus support layer.

In particular, move the IRQ probing out to sparc32/sparc64
arch specific code where it belongs.

Subject: [SPARC64]: Fix for Niagara memory corruption.

On some sun4v systems, after netboot the ethernet controller and it's
DMA mappings can be left active.  The net result is that the kernel
can end up using memory the ethernet controller will continue to DMA
into, resulting in corruption.

To deal with this, we are more careful about importing IOMMU
translations which OBP has left in the IO-TLB.  If the mapping maps
into an area the firmware claimed was free and available memory for
the kernel to use, we demap instead of import that IOMMU entry.

This is going to cause the network chip to take a PCI master abort on
the next DMA it attempts, if it has been left going like this.  All
tests show that this is handled properly by the PCI layer and the e1000
drivers.

Subject: [SPARC64]: Add of_device layer and make ebus/isa use it.

Sparcspkr and power drivers are converted, to make sure it works.
Eventually the SBUS device layer will use this as a sub-class.

I really cannot cut loose on that bit until sparc32 is given the
same infrastructure.

Subject: [ARM] 3634/1: ep93xx: initial implementation of the clk_* API

Patch from Lennert Buytenhek

Add an initial implementation of the clk_* API for the cirrus ep93xx
to the tree.  The initial implementation is somewhat minimal, with the
intention of extending it as we go along.

Subject: [ARM] 3635/1: S3C24XX: Add S3C2412 core cpu support

Patch from Ben Dooks

Add support for the Samsung S3C2412 and S3C2413 range
of SoCs. This patch contains the core identification,
debug macros, and basic register updates to get these
to build.

Subject: [ARM] 3645/1: S3C2412: irq support for external interrupts

Patch from Ben Dooks

Move the decoding of the IRQ_EXT4 and above out of
the entry macro, and into an chained irq handler
as the EXTINT registers move depending on the CPU
being used.

Subject: Add some basic resume trace facilities

Considering that there isn't a lot of hw we can depend on during resume,
this is about as good as it gets.

This is x86-only for now, although the basic concept (and most of the
code) will certainly work on almost any platform.

Subject: [ARM] 3648/1: Update struct ucontext layout for coprocessor registers

Patch from Daniel Jacobowitz

In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext.  Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout.  Define the magic numbers for iWMMXt in the header file for easier
reference.  Include the size of the coprocessor data in the magic numbers.

Also define magic numbers and layout for VFP, not yet saved.
