I am looking at some PV driver issues we are seeing with 32 bit HVM guests 
hosted on 64 bit hypervisor. It looks like the problem can be traced to the 
fact that the hypervisor's view of the shared info structure is different from 
the PV drivers view - The PV driver is built for a 32 bit environment while the 
hypervisor is built for a 64 bit environment. Specifically, the offset for the 
field evtchn_mask is different as seen by the PV drivers compared to what the 
hypervisor thinks it is. How is this issue supposed to be dealt with.

Regards,

K. Y
