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.

The "blocked_list" used for POSIX deadlock detection should only contain
POSIX locks, or posix_locks_deadlock() can get confused.

As I've noted before (but never posted a patch), we should probably stop
checking for deadlock.  POSIX says it's optional for an implementation
to check for deadlock, and since the change to match on tgid, we can
report a deadlock when none exists.

[ Further explanation for Linus: POSIX locks and BSD locks don't block
  each other, so checking that the blocker is a POSIX lock also implies
  that the waiter is a POSIX lock. ]

We need to convert from bytes to blocks, and we also need to
handle the fact that old smbd's will round up the disk usage
bytecount to even multiples of 1MB, and gracefully fall back 
on an estimate based on the file size instead in that case.

Acked by Samuel Thibault who noted the problem in the first
place, and Jeremy Allison wrt smbd behavior.

The recent addition of linux/bitops.h inside linux/kernel.h has
created a circular dependency:

asm/system.h -> linux/kernel.h -> linux/bitops.h -> asm/bitops.h
 -> asm/system.h

which results in an unbuildable kernel.  We appear not to need
linux/kernel.h in asm/system.h, but do need linux/linkage.h, so
make this the case.

From: Doug Dumitru <doug@easyco.com>

I have been fighting a buffering error when sending large amounts of data out
pty devices from UML.  I have tried a couple of patches that did not really
fix the problem (and were rightly rejected by the group), but have finally
found the real bug.

In /arch/um/drivers/line.c there is a function "buffer_data" that is
responsible for storing data into the lines ring buffer.  The function is
"supposed" to return the number of characters actually buffered.
Unfortunately, in the case where the buffer wraps, the "len" variable is
decremented by "end" before it is used as the return parameter.
