Hi,

We were interested in pwrite64/pread64 only since it caused a failure in 
elfutils (see https://bugzilla.redhat.com/show_bug.cgi?id=1174267).
Of course, it applies also to other syscalls. There are the following 
problems:

- Find what syscalls should be changed (check POSIX specification and 
qemu implementation)

- Whether to change them all with "if" statements as for 
pread64/pwrite64. Or there is some more convenient way?

- Find they how to test them all after the change is made (make check?)

What do you think about that?

Best regards,
Ilya Palachev
