Thanks very much for these; this is going to be extremly helpful.  I am 
using these on xen-unstable-bk-1.1518 currently.  One problem: so far I 
have not observed any ticks in xen-syms.  I have tried SDET benchmark, 
which on your previous patches (for xen-2.0-testing), I would get about 
12% of ticks in xen-syms.

This is on a single cpu xen0 domain with no other domains running.  I 
verified that the XENIMAGE and XEN_RANGE were getting passed to 
oprofiled correctly.  I do not specify any active or passive domains 
since this is the only domain running.  Any ideas why I would not get 
any ticks for xen-syms?

Has anyone else tried xenoprofile?

Thanks,

-Andrew
