[Xen-devel] PV drivers for HVM (PAE) guests

We have a build issue when building for PAE guests - the kernel symbol  
__supported_pte_mask is not exported on any of the kernels of interest (2.6.5, 
2.6.9, 2.6.16..) and is used in the function:  pfn_pte_ma (maddr.h) . In this 
scenario, this function is used only by the front-end drivers that are running 
within the unmodified guests.  Would it make sense to have an implementation of 
the function pfn_pte_ma() only for consumption by the PV front-end driver 
modules that does not depend on the __supported_pte_mask variable.
