Right, thanks for the file.  Here's the patch.

Notice how we adjust _both_ the per-cpu loops_per_jiffy, and that we
adjust them with reference to the initial values.

If you adjust lpj with reference to the last, then you 

_will_ build up

a progressively bigger and bigger error in the value over time.

Thanks Russell for the change. This change should fix the global
lpj for UP machine as well when build with SMP_ON_UP.

Can you have a look at below complete change which should
make the BOGOMIPS happy on all OMAP2PLUS machines. Generated
against Kevin's cpufreq branch.

Just compile tested with UP and SMP OMAP builds. After your
review, I can give a test.

Subject: [PATCH] OMAP2+: CPUfreq: update lpj with refernce value to 
avoid progressive error.

Adjust _both_ the per-cpu loops_per_jiffy and global lpj. 
Calibrate them
with with reference to the initial values to avoid a progressively
bigger and bigger error in the value over time.

While at this also re-use the notifiers for UP/SMP since on
UP machine or UP_ON_SMP policy->cpus mask would contain only
the one CPU.

[sp] I thought we were solving a problem - but this makes it
     look like race for addding sign-offs - which I am not
     interested in.
