speedstep-smi only makes sense on Intel mobile Pentium III systems.
So, unify the distributed checks for speedstep_processor there,
and disallow P4s.

I tried to load the new SMP capable powernow k8 driver on a machine
with an too old BIOS. I got a lot of cryptic "init not cpu 0"
messages until the "MP systems not supported by PSB ..." message.

This patch switches the order of the checks around to print the
other message first. It will be still printed multiple times
because the cpufreq setup will probe all CPUs, but that's probably
ok.

The current CPU frequency is already exported one directory upwards, so there
is no need to duplicate it in the ondemand governor.

The SA1100 and SA1110 platforms can handle situations well where the
CPU frequency is different to the value the cpufreq (and timing) code
thinks it is, e.g. when resuming from sleep. So, remove the flags
noting the opposite.

Some daemons try to set the speed to the same speed we're currently
running at. Detect that, and bail out early before we fiddle
with registers and such.

The second part adresses a problem of resetting the max cpu-freq when
unloading the driver. This didn't work for my cpu and I doubt it does
for other. There is no need to pass the computed index of the max.
multiplier in the clock_ratio[] table to longhault_table[] cause the
longhaul_setstate function works with the clock_ratio[] index.
                                                                                                          
Changing the while loop to a for loop with upper limit isn't actually
necessary as long as the driver is bug free, but thats IMHO not yet the
case, so I suggest this change in order to not loop endlessly or read
beyond the limits of the clock_ratio array.

here's a patch that solves some issues I have with the longhaul cpufreq
driver on my epia 6000CL/Via EDEN (actually reporting as CentaurHauls,
family 6, model 7, VIA Samuel 2). The driver tries to compute the fsb speed
while it could actually use the fixed values (as it does for model == 6).
I got this change from the via forum, so no credits to me.

On some platforms (notably power5) you can't enable surveillance
(firmware/service processor watchdog) from the kernel - you have to do
it in the firmware.

This patch changes enable_surveillance() to make the message that is
printed in this situation more informative.  Additionaly, the rtas_call
was changed to rtas_set_indicator so as to avoid having to handle
RTAS_BUSY returns.

The code doesn't actually _care_ about 32/64-bit issues,
only about F_SETLK vs F_SETLKW, and the F_SETLK64 doesn't
exist except as a compatibility thing on 64-bit architectures
(since the regular one already _is_ 64-bit, of course).
