Impact: change calling convention of existing clock_event APIs
struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.
Another single-patch change. For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code:
1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c.
2) i variable is only used when compiling for big endian.
So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

The Freecom-FSG3 is a small network-attached-storage device with the
following feature set:
* Intel IXP422
* 4MB Flash (ixp4xx flash driver)
* 64MB RAM
* 4 USB 2.0 host ports (ehci and ohci drivers)
* 1 WAN (eth1) and 3 LAN (eth0) ethernet ports
* Supported by the open source ixp4xx ethernet driver
* Via VT6421 disk controller (libata and sata-via drivers)
* Internal hard disk (PATA supported, SATA not yet supported)
* External SATA port (not yet supported)
* ISL1208 RTC chip
* Winbond 83782 temp sensor and fan controller
* MiniPCI slot
The ixp4xx_defconfig is also updated to support this device (the
leds-fsg driver is to be submitted separately via the leds tree after
this initial support is merged, as it depends on header gpio defines).

This is a rework of the ixp4xx irq_chip implementation. The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework. The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().
This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

Patch from Deepak Saxena
The expansion bus on the IXP46x NPU can be configured for either 32MiB or
16MiB windows and changing the configuration causes the base address for
each chip select for each region to change. Because of this, we cannot
hardcode the physical base as we currently do. This patch checks the
expansion bus configuration registers at runtime to determine the
appropriate window size. Note that this requires that the bootloader
already configured the device sizes appropriately, but I feel that is
valid assumption to make as the bootloader must configure and access
the flash window, the output display (LCD, LEDs, etc) window, and
other expansion bus devices.

Patch from Rod Whitby
This patch adds support for a new arm/ixp4xx machine - the Iomega NAS 100d network attached storage product. The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card.
Work on porting the latest 2.6.x kernel to this device is being done by
the NSLU2-Linux project (the same team who maintains the port to the
Linksys NSLU2 device). In particular, the majority of this patch was
authored by Alessandro Zummo, based on the work done for MACH_NSLU2
support by the NSLU2-Linux core team of developers.
MACH_NAS100D (as implemented by this patch) can be enabled in jumbo
ixp4xx kernels without any affect on the other machines supported by
that kernel.
This patch applies cleanly against 2.6.15-rc7 and should be trivial to
apply to later kernel versions. It does not depend upon any other
patches.

This patch adds support for the LinkSys NSLU2 running with
both big and little-endian kernels. The LinkSys NSLU2 is
a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.
While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.
A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.

Patch from Alessandro Zummo
This patch fixes AHB/PCI endianness problems when the
processor is in little-endian mode.
The patch configures the CSR register closely following the directives
in [1], paragraph 4.1, page 19.
According to the considerations in [1], page 11, while the AHB bus
supports both endian modes, on the IXP4XX it always uses big-endian.
The PCI bus is connected to the South AHB. A wrong setting in the CSR
register will thus cause a malfunctional PCI bus.
A schematic diagram of the bus interconnections on the IXP4XX
can be found in [1], page 18.
The patch has been verified to work on the NSLU2 in
both LE and BE modes.
The author is Peter Korsgaard.

Building a kernel for IXDP425 currently includes the machine descriptors

This means we can build a kernel that boots on those machines even

such as PCI won't be compiled in. This can lead to many wasted hours
wondering what you have done to your kernel to make it randomly crash
