Add support for PicoPower PT86C523 IRQ router to be used with the in-kernel
yenta driver for CardBus.  With this patch cardbus works on e.g.  Dell
Latitude XPi P150CD.

Initial patch for kernel 2.4 series by Sune Mølgaard
http://molgaard.org/code/linux-2.4.31-picopower.patch

Ported to 2.6.20 by Chmouel Boudjnah (http://www.chmouel.com)

Testing and confirmation that it works by Austin Acton

Cleaned up a little for inclusion in a 2.6.21-rc7 based kernel.

Added some more cleanups according to CodingStyle, as noted by
Randy Dunlap on LKML.

This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).

We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.

We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments.  That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.

Parts of this patch were originally written by Ben Herrenschmidt.

Tested with Malta; inflates malta_defconfig by 3932 bytes.  Ideally there
should be additional configuration to allow getting rid of this overhead
but that would be too much complexity at this stage of the release cycle.

This replaces the MIPS-specific to_tm function with the generic
rtc_time_to_tm function.  The big difference between the two functions is
that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of
rtc_time_to_tm needs to be fixed up.

It was getting a little big, ugly and a primary source for merge conflicts.
Also the old method was a bit too forgiving in that the workaround did
default to off, so now there is an explicit #error forcing platform
maintainers to think if they should enable a workaround for a particular
platform.

It may not be perfect yet but the SB1 code is badly borken and has
horrible performance issues.

Downside: This seriously breaks support for pass 1 parts of the BCM1250
where indexed cacheops don't work quite reliable but I seem to be the
last one on the planet with a pass 1 part anyway.
