This adds a new thermal control framework for PowerMac, along with the
implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and
PowerMac9,1 (latest single CPU desktop). In the future, I expect to move
the older G5 thermal control to the new framework as well.

This patch adds the ability to the SMU driver to recover missing
calibration partitions from the SMU chip itself. It also adds some
dynamic mecanism to /proc/device-tree so that new properties are visible
to userland.

for stats.
The problem is in the ondemand governor, there is a periodic measurement
of the CPU usage. This CPU usage is updated by the scheduler after every
tick (basically, by adding 1 either to "idle" or to "user" or to
"system"). So if the frequency of the governor is too high, the stat
will be meaningless (as mostly no number have changed).
So this patch checks that the measurements are separated by at least 10
ticks. It means that by default, stats will have about 5% error (20
ticks). Of course those numbers can be argued but, IMHO, they look sane.
The patch also includes a small clean-up to check more explictly the
result of the conversion from ns to µs being null.
Let's note that (on x86) this has never been really needed before 2.6.13
because HZ was always 1000. Now that HZ can be 100, some CPU might be
affected by this problem. For instance when HZ=100, the centrino ,which
has a 10µs transition latency, would lead to the governor allowing to
read stats every tick (10ms)!

Go back to what 2.4 kernels used to do here, as if this hits,

Actually an improvement over 2.4 - we now break; out of the loop

We've noticed that sometimes "MTD do_write_buffer(): software timeout"
message was printed out when writing to a Fujitsu NOR flash.
It turned out that this was because of a race in the timeout handling
do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and
sometimes if the timer interrupt handling takes more than one or even two
jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just
after chip_ready() call, the driver bails out from a ready polling loop
despite the chip has actually become ready while all those interrupts were
handled. To deal with this issue, extra check for chip ready is neccessary on
timeout expiration (and the checks should better be reordered).
As do_write_oneword() uses the same approach, it needs to also be changed.
