Patch from Tony Lindgren

Allows translation of shared memory addresses for devices using 
dma-mapping. In some cases the device DMA address is different
from the ARM DMA address, for example with some USB OHCI 
controllers.

For more background information, please see the ARM Linux mailing
list thread "OHCI controller".

Patch from Nicolas Pitre

Let's make it coherent with what the actual code is doing and has
always done, even in 2.4.  Nobody complained about this so let's
just fix the comment.  The most natural usage pattern for this is
a base address and a size so it's more efficient to have an exclusive
end address anyway.

Patch from Ian Campbell

I've seen comments several times that various PXA drivers
update CKEN in an unsafe manner. This patch consolidates
this code into a single function pxa_set_cken() and updates
all the in tree drivers to use it.

Patch from Ian Campbell

The pxafb driver incorrectly allocates 17 u32's for a 16 entry 
pseudo palette.

This cset adds the code to handle the hardware vector floating point
unit found on some ARM926 and later CPUs.  The hardware provides
an implementation for the common cases, and bounces exceptions for
other cases, which have to be handled in software, and signalling
SIGFPE as appropriate.

Patch from Marc Singer

[if's replaced by ifdef's.]

While the BLOB boot loader doesn't support it, there are two others,
UBOOT and Logic's LOLO, that will initialize the SDRAM controller such
that the memory appears as a contiguous region.  This layout to be
required for WinCE and, thus, is the default for these loaders.  The
memory organization had been optimized for discontiguous blocks.  Now,
it supports a default mode that is compatible with all of the
bootloaders as well as options to optimize for either contiguous or
discontiguous models.

Withing, there is also a slight change to the way that the DEBUG_LL
macros select the UART address.  Now it uses immediate constants
exclusively.

Patch from Ian Campbell

Sorry, 1926/2 was missing a brace. Fixed here.

Previous commentry:
I have corrected the grayscale conversion to correctly use the upper
byte rather than the lower one. As requested I have also left the
actual grayscale conversion where it was this time and just dealt with
the palette differences in pxafb_setpalettereg.

fb_alloc_cmap is only called when bits_per_pixel is < 16, otherwise
any existing cmap is freed.

I also fixed up all the spaces and brackets issues (not just the one
you raised previously) this introduces some noise in the patch, if
you'd like the two patches separately please ask.

Since peripheral clocks are be derived in SoC or even platform
specific ways, we need a way to keep this information out of the
drivers.  AMBA Primecells are defined in terms of functional units
where clocks are derived from external sources, and it is up to the
SoC designer to determine where to derive those clocks from.

Therefore, we provide a very basic API which allows platforms to
provide this information in a generic manner to their peripherals.
This framework also allows peripherals to shut down unused clock
sources when they're not in use.

nfs_writepage() refuses to write back mapped pages at all on the page
reclaim path, causing systems to get locked up when there's a lot of dirty
mmapped data around.  The patch changes NFS so that it will start I/O
against these pages.

The code as it stands is designed to defer writeout to pdflush which can do
larger, more efficient I/Os.  But there shouldn't be much traffic by this
path, and going slow is better than not going at all.

VIA chipsets are broken and don't work with IOMMU enabled. For some mysterious
reason (the IOMMU logic is actually in the CPU) they manage to corrupt all
data going through the aperture to PCI devices.

There was a workaround previously that enabled the slower softmmu when VIA is 
detected on the normal IOMMU path (when there is more than 3GB of memory). But
CONFIG_IOMMU_DEBUG took a short cut that was not handled, which ended up with 
VIA systems not booting when this option is enabled.

This patch enables the workaround with CONFIG_IOMMU_DEBUG/iommu=force too

The fast system-call fall-back-path has a race: it reads PSR, modifies
some bits, then writes back the new PSR.  Unfortunately, the contents
of PSR may change between reading and writing it.  For example, an
interrupt could occur which could trigger a context-switch.  The
context-switch might in turn flush the floating-point-high (FPH)
partition to memory, clear PSR.MFH, and set PSR.DFH.  To prevent this
race, the patch below turns off PSR.I before reading PSR.

This fixes a floating-point corruption problem that was observed on a
system with a libc which has the fast system-call support enabled.

The performance impact is minimal (on the order of a handful of cycles).

I waffled over this for ages.  On balance, I think it's best to mark those
bh's as uptodate.

And on reflection, I'm not sure why we go bringing ramdisk blockdev pages
uptodate all over the place anyway.  But ramdisk is weird and it passes
testing.  Let those dogs sleep.
