Hi all,

I've done some more cleanup on the amd76x_pm module. Looks like Pasi and
I both did pretty much the same changes last time independently, but Pasi
chopped off even more unnecessary code. So I've continued the cleanup based
on Pasi's code.

I've done some cleanup to remove my old comments and to get rid of all 
the ifdefs. This makes the code more readable and makes it easier to
develop. I've also changed the functions around a bit to group them
better, and changed variable naming to be more standard. I've only edited
the amd76x_pm.c file, and did not do any functional changes. Just cleanup.

On the clock skew problem, it's still there, and to figure out how bad the
problem is, I've done a little shell script based on the earlier thread on
adjtimex on this mailing list. You can get the skewtest.sh from:

On my S2460 system with a pair of Athlon 1400's I get the following results:

                            suggested tick
Without amd76x_pm module:   10002
With amd76x_pm module:      between 9952 - 9977

I guess some people see much worse skew on some systems? Can you please 
run the skewtest.sh and post some results, thanks.

Following is the current patch, you can also get it from:

I may not have access to my Athlon box for next few weeks, but hopefully 
Pasi keeps maintaining the module as needed.
