OK, I commented out the call to move_addr_to_kernel() and tried to load
the module, but it fails with:

[linux-2.6.26-rc2]# insmod net/rds/rds.ko
insmod: error inserting 'net/rds/rds.ko': -1 Cannot allocate memory

and the below errors at the dmesg, which seems harder to bypass just with
commenting out things (eventhough that I will try it!) can you help in
that, providing direction, etc.

thanks,

Or.
