Cleanup/Restructuring of drivers/char/watchdog/Kconfig

Version 0.06 of the intel i8xx TCO driver:
* change i810_margin to heartbeat (in seconds)
* use module_param
* added notify system support
* renamed module to i8xx_tco

Added notifier support
Moved start and stop code to their own subroutines
Extended ioctl support
Add MODULE_* info

small cleanup

Update MODULE_* information

Make heartbeat a module parameter and some general clean-up.

In order to make the watchdog menu useful for some architectures, we need
to only be able to select the watchdogs that can compile.  This patch also
moves the SuperH watchdog from its own Kconfig file to the normal one.

This is nonsense. We only use the lower 8 bits, so putting the useful
info in the upper 8 makes no sense at all.

Cpufreq core expects units in khz not mhz. Oops.

It broke some existing setups, so let's drop it until we have
a better notion of how to do this.

This is an obvious scalability improvement for write()s.  We used a
global lock to protect the inode writecount (updated on every open for
writing) - this just makes it use the existing inode->i_lock instead.

Compiles & boots fine on x86 SMP.

Another fix from Dominik.

From Dominik..
The different P-4-M steppings have different "ebx" values. Analyze it
correctly to sort out Pentium-4-based Celerons.

Move the table verification to an extra function.

Remove the *ppst table, and remove an unneccessary forward-declaration

Keep *ppst local to the only function which needs it any longer.

Use the frequency_table for calculating the correct ->target state

Add a struct cpufreq_frequency_table, fill it with content, and use it for
->verify.

Reverting frequency changes on unloading is uncommon for cpufreq drivers
so let's remove this speciality.

I mistook a Geode chipset's register meanings. (-.-;
ON is not 'CPU is ON' but 'cpu modulation is ON' that is stops cpu.
                                                                                                               
this causes a bad freq setting.
                                                                                                               
This patch fixes this and minor bug that is,
                                                                                                               
        if (new_khz == stock_freq) {  /* if new khz == 100% of CPU speed, it is special case */
                local_irq_save(flags);
                cpufreq_notify_transition(&freqs, CPUFREQ_PRECHANGE);
                                                                                                               
cpufreq_notify_transition() called after local_irq_save();
this makes not update cpu_khz.

Periodically check for outstanding MCA or INIT records and pass them to
user space salinfo.

Correct the "did we recover from MCA test" and move it up a level to
simplify interaction with debuggers.

Thanks to Nick's domain patch, the kernel worked fine with
smp_num_siblings = 4 (in simulation).
