    - revert broken hunk in vserver patch
    
    After the following change that went into 3.13.9 and 3.14+, vserver
    enabled kernels couldn't boot anymore, hanging at the first interaction
    with udev in initrd. Reverting the change to follow_dotdot() in
    fs/namei.c makes the kernel boot again without problems.
