Bug Description

    commit 8f9c0119d7ba (compat: fs: Generic compat_sys_sendfile
    implementation) changed the PowerPC 64bit sendfile call from
    sys_sendile64 to sys_sendfile.

    Unfortunately this broke sendfile of lengths greater than 2G because
    sys_sendfile caps at MAX_NON_LFS. Restore what we had previously which
    fixes the bug.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
