Hi,

I have done the following experiments and have posted the results

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

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