There's an issue with bio_uncopy_user() in that it expects ->bv_len to
be untouched from io submission to io completion, which it wont be for
some transfer lengths on some hardware. So we end up not copying all the
data back to user space, not so good. This patch adds a bio_map_data
local structure to track the io_vec.

The "DART" iommu used on Apple U3 chipset will appear into 3rd party
products soon, thus the code shouldn't be named "pmac_*" anymore.

Also, the explicit config option is no longer needed, there is no
reason to build a PowerMac kernel without the iommu support, and
it can always be disabled at runtime with a cmdline option for
testing or debugging.

This patch do the appropriate renaming and makes the config option
implicit & selected when pmac support is included.

include/asm-ppc64/systemcfg.h defines a structure that currently gets
exposed to userland via /proc, and which I intend to deprecate in the
near future once I have better alternatives available.

In the meantime, this patch removes a bunch of stuff from this file that
were only defined for non-__KERNEL__, like an inline function for
getting to that struture via /proc, and some CPU & platform type
definitions that were duplicates of the ones in asm-ppc64/processor.h.
These things have nothing to do in a kernel header.

There appears to be one case missing from the wait_event() family - the
uninterruptible timeout wait.  The following patch adds this.

This wait is particularly useful when (eg) you wish to pass work off to an
interrupt handler to perform, but also want to know if the hardware has
decided to go gaga under you.  You don't want to sit around waiting for
something that'll never happen - you want to go and wack the gremlin which
caused the failure and retry.

This fixes the bug that made the card DMA lots of data to random memory
locations, causing lockups and instant reboots. 

The problem was that the yoffset variable got modified inside the loop,
but the logic in the switch statement was meant to work on the initial
value of the yoffset variable.
