We removed asm/mach-types.h from asm/hardware.h.  This means we must
now include asm/mach-types.h where its used.

We also fix h3600 pcmcia initialisation/cleanup.

Traditionally, the Assabet reverses its mapping of UART1 and UART3
when the Neponset board is connected.  This can be (a) confusing
and (b) annoying when the boot loader uses UART1.  We therefore
have a fixed mapping between the ttySA names and the physical
UARTs on this platform.

The patches convert drivers/pcmcia to use C99 named initializers,
and all the patches are against 2.5.42. There are 25 patches in
total, and the "cat"ing them together they're more that 20K, so
I'm sending the patches as a compressed attachment. The patches
were CC'd to Linus in the first mail that bounced.

Here's a small set of patches that switch the code to use C99
desiginated initializers. Patches are against 2.5.42.

Prevent the assembler putting constant pools in the middle of code.
Clean up shark ISA PIC handling.

This cset removes the global irq handling in the AcornSCSI driver,
and makes the target type for bitops an unsigned long array rather
than an unsigned char array.

Remove unnecessary use of __inline__, and remove a few unnecessary
prototypes.  copy_buffer is moved before use.

This removes a compilation warning and makes the code smaller.
It is also more obvious what's going on.

The USB gadget code now lives in arch/arm/mach-sa1100/usb, and
isn't in a mergable state.  We remove the old makefile entries
which are never going to be satisfied, and leave a placeholder for
the usb directory.

dump_stack() got used by the generic code.  Call our version
__dump_stack since we're running out of other descriptive names.
Allow show_trace_task to show the backtrace for the current
thread.

Add rudimentary support for Thumb ptracing; we aren't able to single
step through thumb branches yet, but this change provides enough
infrastructure to make this possible.

This cset updates (as much as is possible) the NCR5380-based Acorn
SCSI drivers, mainly converting them to the new error handling code.
However, they still don't build due to errors in NCR5380.

Vojtech has patches that bring their counterparts in the input
subsystem up to date (and into a working state) so these drivers
are no longer required.

This cset also fixes the Acorn i2c RTC code.

This cset combines the Atomwide and The Serial Port 16550 driver
modules into one "8250_acorn.c" driver.  This new module takes full
advantage of the LDM-based expansion card facilities.

This cset implements validity checks on the ethernet MAC address when
the device is opened, and refuses to open the device if this check
fails.  We also provide the set_mac_address method to allow ifconfig
to change the mac address to something valid.

In addition, the driver is converted from the old expansion card
discovery methods to the new device model driver framework.

Provide LDM-based driver registration/removal interface for drivers
to use.  We make the old device discovery code ignore devices
claimed via the LDM framework.  However, the LDM framework ignores
devices that may be in use by the old device discovery code.  This
is fine since the only devices that will still use the old discovery
code will be SCSI drivers.

Currently, we don't provide a useful dev.name entry.

This updates the Integrator cpufreq code to use the new interfaces,
and makes the sa1100 cpufreq round up the requested frequency.

The second serial port is never present in these machines, so its
pointless listing it in the first place.

- ide_register_hw takes two arguments, not one.
- ide_fix_driveid is no longer used.

This adds ARM support for in_atomic() and asm/numnodes.h

This updates these neponset and sa1111 support to use the new system
device infrastructure in the Linux device model.

Sanitise includes of asm/tlbflush.h, asm/cacheflush.h, asm/proc-fns.h
Implement ARM-specific TLB "shootdown" code.  It turns out that it
is overall more efficient to unconditionally invalidate the whole
TLB rather than entry by entry when removing areas.

This cset fixes the RiscPC decompressor code for the PIC changes.

We use a pointer to a structure rather than a structure to access
params.  With a PIC decompressor, the address of the structure gets
PIC-ified which is not what we want.

Update pcibios_enable_device to only enable requested resources,
mainly for IDE.  Supply a pci_mmap_page_range() function to allow
user space to mmap PCI regions.

This updates the ARM time keeping functions to use tick_nsec/1000
instead of tick.

To keep the Config.in files relatively clean, we use the
following construct:

 if [ "$CONFIG_ARM" = "y" ]; then
    dep_tristate 'Foo' CONFIG_FOO $CONFIG_BAR
 fi

where CONFIG_BAR is some machine implementation or high-level
chip support configuration option.  If CONFIG_BAR is left
empty, then the tristate is offered to the user, which isn't
what we want.  Defining CONFIG_BAR to 'n' prevents the option
being offered.

This is a rule I generally try to implement within
arch/arm/config.in.

This cset makes CONFIG_SA1111 and CONFIG_ARM_THUMB behave that
way.

Since the decompressor supports PIC, even for CONFIG_ZBOOT_ROM,
we can easily allow an image which has been linked to run at
a particular address in ROM to be moved to RAM.  We just need
to make sure that we don't relocate the GOT entries for the
BSS segment.

This cset also implements sa1100-based debugging for the
decompressor.

These two variables are used by more than just the linker;
they're also used by head.S to know where it can safely
place the page tables.  We therefore need to export it
from the Makefile.

These are also highly machine dependent; we don't want
to duplicate the same set of conditionals for cpp and
for the makefiles.

arch/arm/Makefile also contained a stray close-paren.  I'm
submitting this one to the lost property office.

We also always pass -mno-fpu to the assember; this
guarantees that any floating point will be caught.

SPARC was unconditionally setting CONFIG_SERIAL_CORE_CONSOLE to y
and conditionally setting CONFIG_SERIAL_CORE depending on the Sparc
sub-drivers.  In addition, the core serial driver for SPARC is
always built, so we end up with link errors.

We instead make CONFIG_SERIAL_CORE{,_CONSOLE} dependent on building
the SPARC core driver (CONFIG_SERIAL_SUNCORE).

uses fields that do not exist otherwise.

Due to some bugs in byteorder/generic.h linux would always use C handcoded
swab64 for 64bit ntohq or cpu_to_be64.  The C version is very inefficient
and expands to 30+ instructions of horrible code.

This hurts on filesystems that use on disk big endian data structures
with 64bit data types.

This patch adds an assembly optimized swab64 to fix it. Now bswab64 is
4 instructions when your CPU supports bswap and 9 when it doesn't.
Tests were done with gcc 3.2, may be different on older gcc.

This is good for ~600 bytes code size reduction in XFS (gcc 3.2):
Before:
 503199    3296    1682  508177   7c111 fs/xfs/xfs.o
After:
 502543    3296    1682  507521   7be81 fs/xfs/xfs.o

Also should be faster.

Also some minor cleanups in the file.
