An accept() call on a SCTPv6 socket that returns due to connection of
a IPv4 mapped peer will fill out the 'struct sockaddr' with a zero
IPv6 address instead of the IPv4 mapped address of the peer.

This is due to the v4mapped flag not getting copied into the new
socket on accept() as well as a missing check for INET6 socket type in
sctp_v4_to_sk_*addr().

This updates some error reporting paths in SPI device setup:

 - Move validation logic for SPI chipselects to spi_new_device(),
   which is where it should always have been.

 - In spi_new_device(), emit error messages if the device can't
   be created.  This is LOTS better than a silent failure; though
   eventually, the calling convention should probably change to
   use the <linux/err.h> conventions.

 - Includes one previously-missing check:  SPI masters must always
   have at least one chipselect, even for dedicated busses which
   always keep it selected!

It also adds a FIXME (IDR for dynamic ID allocation) so the issue doesn't live
purely in my mailbox.

This patch fix weird behaviour of UDF mounting procedure.  To get UID
changed (for now) we have to type

	mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point

and specifying two uid at once is strange a bit.  So with the patch we are
able to mount without additional 'uid=ignore' option.  The same for GID
option is done.

This patch will not break current mount scheme (with two option).

Btw this does fix (I hope) the following

Coverity spotted what looks like a real possible case of using a variable
after it has been freed.  The problem is in
kernel/relay.c::relay_open_buf()

If the code hits "goto free_buf;" it ends up in this code :

  free_buf:
    	relay_destroy_buf(buf);	<--- calls kfree() on 'buf'.
  free_name:
   	kfree(tmpname);
  end:
  	return buf;		<-- use after free of 'buf'.

I read through the callers and they all handle a NULL return from this
function as an error (and hitting the 'free_buf' label only happens on
failure to chan->cb->create_buf_file(), so that looks like a clear error to
me).

The patch simply sets 'buf' to NULL after the call to
relay_destroy_buf(buf); - as far as I can see that should take care of the
problem.

The patch also corrects a reference to a documentation file while
I was at it.

Note from Mathieu: the documentation reference change should have been
done in a separate patch, but I guess no one will really care.

WARNING: kernel/built-in.o(.text+0x16910): Section mismatch:

kthreadd_setup() which is __init. But this is ok, because kthreadd_setup()
is only ever called at init time, and then kthreadd() proceeds into its
"for (;;)" loop. We could mark kthreadd __init_refok, but kthreadd_setup()
with just one callsite and 4 lines in it (it's been that small since
10ab825b) doesn't need to be a separate function at all -- so let's
just move those four lines at beginning of kthreadd() itself.

This is only called at init time and only happens if the BIOS screws
something up, so the leak is slight and it is probably not worth sending to
2.6.22.x.  The driver would not initialize the interface in the case, and I
have no reports of this happening.  I have booted and run tests on a system
with this patch.  Note that the original patch was munged by the mailer,
here's a new one.

If we ever hit the "default:" case in the switch in try_init_dmi(),
then we'll leak the storage allocated with kzalloc() and assigned
