With help from Yoshfuji Hideaki.

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.

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).

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.
