The iMac G5 and latest single-cpu PowerMac G5 have seen the venerable PMU
(Power Management Unit) chip been sent to well deserved retirement.  It has
been replaced by a newcomer, the SMU (System Management Unit ?) which is of
course totally undocumented and has no open source darwin driver...  The
SMU chip is responsible of initializing the chipset & CPU (boot process),
power supply control, real time clock, fan control, provides some i2c
busses, etc...  etc...  etc...

This is a very basic driver based on the Open Firmware methods for
accessing this chip.  It provides synchronous functions only, and does
restart, shutdown, and real time clock access.  There is still no fan
control, at least not until we have figured out how to access the fans via
the SMU.

The initial code was written by J.  Mayer <l_indien@magic.fr>, I mostly
rewrote it to better adhere to our coding style standards ;)

The patch also updates the g5_defconfig to include the SMU support by
default.

The iMac G5 has some issues with Apple chips not having a valid

that it only relies on the Open Firmware informations which are correct.

The iMac G5 and new single CPU PowerMac G5 come with a new revision of the
K2 ASIC called Shasta.  The PATA cell in there now does 133Mhz.  This patch
adds support for it.  It also adds some power management bits to the old
100MHz cell that was in Intrepid based ppc32 machines.  The original iMac
G5 bits are from J.  Mayer <l_indien@magic.fr>

The ppc64 vDSO is still exporting LINUX_2.6.11 (from -mm) for symbol

I noticed that with the vDSO patch in 2.6.11-bk, it's almost possible to
build the kernel with the fedora biarch toolchain.  However, I still get
warnings from ld about zImage being the wrong architecture, unless I change
the script as shown in this patch.

I'm not sure if this breaks setups with old binutils that might not
understand powerpc:common, otherwise please apply.

AC97 Codec
This patch series adds support for the WM9713/WM9714 family of AC97
codecs. This family is different from 'standard' AC97 codecs in that the
default codec power state is 'off'. i.e. performing a register reset
will power the device down.

This patch also adds better support for larger single/double channel
enumerated mixer types.

This patch fixes a bug with the recently added printk-times feature.

In the case where a printk consists of only the log level (followed
subsequently by printks with more text for the same line), the printk-times
code doesn't correctly recognize the end of the string, and starts emitting
chars at the 0 byte at the end of the string.

The patch below fixes this problem.  It also adjusts the handling of
printed_len in the routine, which was affected by the printk-times feature.

This patch updates the sungem driver. I reworked all of the PM stuff, making it
less prone to races, probably simpler to read as well, and I no longer shut the
PHY down when the interface is down so that things like laptop-net no longer
die (the gain in power consumption was minimal, not worth the pain). I also
implemented basic WOL support.

There is still something I'm not totally happy with in the locking
(explained in the comment at the beginning), basically too much locking and a
couple of places with delays in locks. I will try to improve these later on.

It also adds a fix for a MAC reset issue when the receiver gets stuck.

This check is wrong, gcc optimizes it away:

                if ((len -= sizeof(pi)) > len)
			return -EINVAL;

This could be responsible for the BUG. If len is 2 or 3 and TUN_NO_PI
isn't set it underflows. alloc_skb() allocates len + 2, which is 0 or
1 byte. skb_reserve tries to reserve 2 bytes and things explode in
skb_put.

a performance hit because we end up constantly moving entries around
