Hi Stephane,

I have been looking through the perfmon2 code to see how it is going to 
work with OProfile. It looks like the ia64 oprofile support has not been 
modified to work with the changes in perfmon2. Has the ia64 kernel been 
built with perfmon2 and oprofile support? I don't have easy access to an 
ia64, so I haven't been able to verify that the attached patch works. 
However, I expect that the changes in the patch will be required for 
OProfile to function with perfmon2.
