Patch from Richard Purdie

The Sharp SL-Cxx00 models have a combined power control for the SD
and CF slot 0. This patch adds hooks to the scoop driver to allow
machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.

It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of
warnings when compiling for collie are also fixed.

Patch from Lennert Buytenhek

Since we have to use XCB=101 instead of XCB=000 on the ixp2400 to
prevent it from regularly falling over, and since we have to deal with
manual write buffer flushing because of that, we might as well use
XCB=101 on all ixp2000 platforms since it's faster than XCB=000.

nwfpe extended precision emulation used to be broken on big-endian
and was therefore disabled.  This patch fixes nwfpe so that it copies
extended precision floats to/from userspace in the proper word order
(similar to patch #2046, see the description of that patch for an
explanation) and reenables the Kconfig option.

Patch from Lennert Buytenhek

The routine that nwfpe uses for converting floats/doubles to
extended precision fails to zero two bytes of kernel stack.  This
is not immediately obvious, as the floatx80 structure has 16 bits
of implicit padding (by design.)  These two bytes are copied to
userspace when an stfe is emulated, causing a possible info leak.

Make the padding explicit and zero it out in the relevant places.

The sys_ptrace boilerplate code (everything outside the big switch
statement for the arch-specific requests) is shared by most architectures.
This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
arch_ptrace.

Some architectures have a too different ptrace so we have to exclude them.
They continue to keep their implementations.  For sh64 I had to add a
sh64_ptrace wrapper because it does some initialization on the first call.
For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

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.

Patch from Nicolas Pitre

We have an optimized sha1 routine (arch/arm/lib/sha1.S) meant to
override the generic one in lib/sha1.c.

Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the
link argument list and therefore the architecture specific lib functions
are not picked up before the generic versions.

This patch is a quick fix to change that ordering for ARM.  Here's what
the kbuild maintainer had to say about it (was also CC'd on lkml):

This provides support for IXP2xxx error interrupt handling. Previously there was a patch to remove this (although the original stuff was broken). Well, now the error bits are needed again. These are used extensively by the micro-engine drivers according to Deepak and also we will need it for the new EDAC code that Alan Cox is trying to push into the main kernel.
