In separating out support for hardware floating point we missed the fact
that both POWER3 and POWER4 have HW FP. Enable CONFIG_PPC_FPU for POWER3
and POWER4 fixes the issue.

This change from March 3rd causes the partition parsing code to ignore
partitions which have a signature byte of zero. Turns out that more people
have such partitions than we expected, and their device numbering is coming up
wrong in post-2.6.11 kernels.
So revert the change while we think about the problem a bit more.

There's a slight bug in the routines in that if the period requires dt,
then the routine will unconditionally set it. DT may only be set if
Wide is also set, so this turns back on the wide bit.
For domain validation to work correctly, we need to observe the wide bit
absolutely.

The defines in bootinfo.h are not used, so the include can be removed.
According to Ben, birecs are not used on ppc64:
on ppc64, we made the decision of enforcing the presence of an
OF device-tree and either an OF-like client interface or a kexec
like flattened tree.
so if your bootloader want to say things to the kernel,
it can do so by adding properties to the device-tree

The code in unflatten_device_tree knows that get_property is written to
only return with lenp equal to 1 when also returning a valid pointer.
The gcc 3.3.3 compiler is not able to prove this to itself, so it warns
about a possible uninitialized pointer dereference:
.../arch/ppc64/kernel/prom.c: In function `unflatten_device_tree':
.../arch/ppc64/kernel/prom.c:828:
warning: `p' might be used uninitialized in this function
Unless it is desired to rework the interaction between the two

Attached is a patch to bttv which fixes the following problems.
Affected cards and problems:
~~~~~~~~~~~~~~~~~~~~~~~~
o VP-1020 (200103A) Tuning problems, device detection.
o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while.
o VP-1030 (DST-CI) Tuning sometimes fails after CI commands.
o VP-2031 (DCT-CI) Tuning problems
The timeout happens before the actual timeout occured in the MCU
on the board, and hence the problems.
Changes: (bttv-i2c.diff)
~~~~~~~~~~~~~~~~~~~~~~~~
o Changed the custom wait queue to wait_event_interruptible_timeout()
- Suggestion by Johannes Stezenbach.
o Fixed the wait queue timeout problem
- This fixes the timeout problem on various cards.
- This problem was visible as many
* Cannot tune to channels, when signal levels are very low.
* app_info does not work in some conditions for CI based cards
- Smaller values worked good for newer cards, but the older cards
suffered, settled down to the worst case values that could happen in any
eventuality.

This patch adds support for a new class of DAC960 controllers. It's based
on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a
fork of the 2.4.18 version of DAC960 that adds support for this new type of
controllers (internally called "GEM Series"), that differ from other DAC960
V2 firmware controllers only in the register offsets and removes support
for all others.
This patch instead integrates support for these controllers into the DAC960
driver.
Thanks to Anders Norrbring for pointing me to the idac320 driver and
testing this patch.
No Signed-Off: line because all code is either copy & pasted from IBM's
idac320 driver or support for other controllers in the 2.6 DAC960 driver.
Note: the really odd formating matches the rest of the DAC960 driver.
