  - linprocfs.c 1.96:
    Improve linprovfs to provide/fix the
     - process state (idle, sleeping, running, ...) [1]
     - the process group ID of the process which owns the connected tty
     - some page fault stats
     - time spend in kernel/userland
     - priority/nice value
     - starttime [1]
     - memory/swap stats
     - scheduling policy
  
    Additionally add some new fields and correct some not filled out ones.
  
    This brings us down to 15 dummy fields.
  
    The fields marked with [1] are needed to get Oracle 10 running. The starttime
    field is not completely right, since it displays the _same_ starttime for
    _every_ process, but at least it is not 0 and Oracle accepts this.

  - pseudofs_vnops.c 1.60:
    Correctly calculate a buffer length. It was off by one so a read() returned
    one byte less than needed.

  All of those are needed for Oracle 10. Since previous Oracle versions work
  just fine without those fixes, these patches can be seen as regression fixes
  too. Because of this I think they are a RELENG_6_x candidate (MFC reminder
  set).
