RE: [Xen-devel] [XENOPROLIFE] New oprofile patch for XenOProfile

["Santos, Jose Renato G" <joserenato.santos@xxxxxx>]

 Do you get versions 1 and 2 working with 32bit Xen?
 Could you please send me Rosimildo patches. I don't think I have it and
I would like to compare with the others.
 Thanks

  Renato
