non-exit code.

Instead of detecting when filp->private_data becomes NULL in
do_tty_hangup and check_tty_count, we remove the file descriptor
from the list of descriptors associated with the tty.  We use the
same method that dentry_open() uses.

(It also cleans that up to use a "file_kill()" instead of using a dummy
"kill_list()" that leaves pointers to stale stack entries that are never
used)

In addition, we change the for() loops into real list_for_each()
or list_for_each_entry loops as appropriate.

The patch below removes an unneeded #if from net/ipv6/af_inet6.c:
- kernel 2.0 is too ancient to check for
- the MODULE_* macros have empty definitions #if !MODULE

Move printing the header to s_start, removing the need for the special
pointer value.

This patch moves over printing of the various struct Scsi_Host
attributes from procfs functions in the sg driver to sysfs.

Not only is this the much more logical place for them, but with some
more work on the pcmcia drivers this will allow us to make
scsi_host_get_next() private to the midlayer for implementing
refcounting and cleaning up locking in that area.
