fioctl retrieves wrong file address for ramfs

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In conf/rootfs/ create files 'foo' and 'bar' with some data in both
2. Try `fioctl(fopen(file_name, "r"), 0, &file_addr));` for both 'foo' and 
'bar' files
3. Check the results in file_addr variable

What is the expected output? What do you see instead?
I see random values (often zeroes) that may vary in case of changing linkage 
options (RAM start, etc.)
