Thread-topic: Enable GNTTABOP_copy hypercall for HVMs
Please don't use the patch sent in the previous mail as it wasn't taken with 
diff -u. I am resending the patch file with the unified diffs that Keir signed 
off. This is the same patch as I sent in the first mail.

This patch is for enabling the GNTTAB_copy hypercall for HVMs. For 64 bit 
guests the grant_table.c functionality is used as is done by PVs but for 32 bit 
guests on 64 bit Xen, the compat/grant_table.c functionality is used. 

This patch applies cleanly on the latest xen-unstable cset.
