This is the second patch of three implementing further llseek cleanups,
against 2.5.4-pre1.  It does not depend on the other patches.

This patch cleans up various code and quite nicely removes much more
code than it adds.  Specifically:

- remove static lseek method which merely reimplements
  the standard no_llseek in the following seven files:
  hci_vhci.c, ite8172.c, nec_vrc5477.c, auerswald.c,
  pipe.c, netlink_dev.c, and socket.c

- remove fs/ufs/file.c::ufs_file_lseek -- Al says it is
  reimplementing generic_file_llseek, so let's use that
  instead (the comment about 32-bit sizes shouldn't be
  an issue, the generic method checks size)

- include smp_lock.h in 3 files missed from previous
  'remove bkl' patch

- Documentation/filesystem/Locking update

Please, apply.
