You're right, I checked it out and found that libpciaccess has a set of old and 
deprecated memory mapping functions to map/unmap entire BARs (regions). Later, 
they added new functions to allow manny mappings in the same region. Which are 
the ones we are using, tough we use them to map entire regions anyway.

I updated the libpciaccess patch to allow offsets inside the region. I also 
created a new patch for the arbiter to stop using libpciaccess region->memory 
pointer, which is deprecated.
