You need both sides of the system to agree on 64-bit. It 
doesn't help if your kernel can address 64-bit if your
applications call 'int fgetpos(...)' and assumes int being
32 bits long. The changes in the kernel are trivial (and
mostly done anyway). You need to check all of your applications
and inspectg what they do with the return to systemcalls.
