    Switch smb2 code to use per session session key and smb3 code to
    use per session signing key instead of per connection key to
    generate signatures.

    For that, we need to find a session to fetch the session key to
    generate signature to match for every request and response packet.

    We also forgo checking signature for a session setup response
    from the server.

Add a variable specific to NTLMSSP authentication to determine
whether to exchange keys during negotiation and authentication phases.

Since session key for smb1 is per smb connection, once a very first
sesion is established, there is no need for key exchange during
subsequent session setups. As a result, smb1 session setup code sets this
variable as false.

Since session key for smb2 and smb3 is per smb connection, we need to
exchange keys to generate session key for every sesion being established.
As a result, smb2/3 session setup code sets this variable as true.

Move the post (successful) session setup code to respective dialect routines.

For smb1, session key is per smb connection.
For smb2/smb3, session key is per smb session.

If client and server do not require signing, free session key for smb1/2/3.

If client and server require signing
  smb1 - Copy (kmemdup) session key for the first session to connection.
         Free session key of that and subsequent sessions on this connection.
  smb2 - For every session, keep the session key and free it when the
         session is being shutdown.
  smb3 - For every session, generate the smb3 signing key using the session key
         and then free the session key.

There are two unrelated line formatting changes as well.

The existing NLS case conversion routines do not appropriately handle
the (now common) case where the local host is using UTF8. This is
because nls_utf8 has no support at all for converting a utf8 string
between cases and the NLS infrastructure in general cannot handle
a multibyte input character.

In any case, what we really need for cifs is to emulate how we expect
the server to convert the character to upper or lowercase. Thus, even
if we had routines that could handle utf8 case conversion, we likely
would end up with the wrong result if the name ends up being in the
upper planes.

This patch adds a new scheme for doing unicode case conversion. The
case conversion tables that Microsoft has published for Windows 8
have been converted to a set of lookup tables, and a routine is
added to convert a wchar_t from lower to uppercase using those
tables.

server->ssocket pointer got zeroed out. In most places, that we access

The only actual current lockref user (dcache) uses zero reference counts
even for perfectly live dentries, because it's a cache: there may not be
any users, but that doesn't mean that we want to throw away the dentry.

At the same time, the dentry cache does have a notion of a truly "dead"
dentry that we must not even increment the reference count of, because
we have pruned it and it is not valid.

Currently that distinction is not visible in the lockref itself, and the
dentry cache validation uses "lockref_get_or_lock()" to either get a new
reference to a dentry that already had existing references (and thus
cannot be dead), or get the dentry lock so that we can then verify the
dentry and increment the reference count under the lock if that
verification was successful.

That's all somewhat complicated.

This adds the concept of being "dead" to the lockref itself, by simply
using a count that is negative.  This allows a usage scenario where we
can increment the refcount of a dentry without having to validate it,
and pushing the special "we killed it" case into the lockref code.

The dentry code itself doesn't actually use this yet, and it's probably
too late in the merge window to do that code (the dentry_kill() code
with its "should I decrement the count" logic really is pretty complex
code), but let's introduce the concept at the lockref level now.

Pull networking fixes from David Miller:
 "A quick set of fixes, some to deal with fallout from yesterday's
  net-next merge.

   1) Fix compilation of bnx2x driver with CONFIG_BNX2X_SRIOV disabled,
      from Dmitry Kravkov.

   2) Fix a bnx2x regression caused by one of Dave Jones's mistaken
      braces changes, from Eilon Greenstein.

   3) Add some protective filtering in the netlink tap code, from Daniel
      Borkmann.

   4) Fix TCP congestion window growth regression after timeouts, from
      Yuchung Cheng.

   5) Correctly adjust TCP's rcv_ssthresh for out of order packets, from
      Eric Dumazet"

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.12 series:

   - A new driver for the TZ1090 PDC which is used on the metag
     architecture.

   - A new driver for the Kontron ETX or COMexpress GPIO block.  This is
     found on some ETX x86 devices.

   - A new driver for the Fintek Super-I/O chips, used on some x86
     boards.

   - Added device tree probing on a few select GPIO blocks.

   - Drop the Exynos support from the Samsung GPIO driver.

     The Samsung maintainers have moved over to use the modernized pin
     control driver to provide GPIO for the modern platforms instead.

   - The usual bunch of non-critical fixes and cleanups"

This reverts commits 61e00655, 73f8645d and 8e22ecb6:
  "Input: introduce BTN/ABS bits for drums and guitars"
  "HID: wiimote: add support for Guitar-Hero drums"
  "HID: wiimote: add support for Guitar-Hero guitars"

The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic.  It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.

We'll try again for 3.13.
