Hi,

I have done the following experiments and have posted the results
below.


Average of 5 iterations:
------------------------------------------------------------------------------
------------------------------------------------------------------------------

Kernbench make -j16 results on a
16 core x86 machine _with_deep_sleep_ support (C1,C2,C3)


Without the patches applied			With the patches applied


	31.8s						30.4s

------------------------------------------------------------------------------
------------------------------------------------------------------------------


Kernbench make -j8 results on a
8 core x86 machine _without_deep_sleep_ support (only mwait)


Without the patches applied			With the patches applied


	20.2s						20.4s

------------------------------------------------------------------------------
------------------------------------------------------------------------------

Kernbench make -j8 results on a 8 core _dedicated_lpar_pSeries_ machine


Without the patches applied                     With the patches applied


	4m, 37s						4m, 36s

------------------------------------------------------------------------------
------------------------------------------------------------------------------

Please let me know if any other kind of testing is necessary.


Based on the feedback, I will post out the next iteration with a few
minor bug fixes.


thanks,
arun
