ef01578615 [TCP]: Fix sk_forward_alloc underflow in tcp_sendmsg
I've finally found a potential cause of the sk_forward_alloc underflows
that people have been reporting sporadically.

When tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don't
check sk_forward_alloc even though a large amount of time may have
elapsed since we allocated the page.  In the mean time someone could've
come along and liberated packets and reclaimed sk_forward_alloc memory.

This patch makes tcp_sendmsg check sk_forward_alloc every time as we
do in do_tcp_sendpages.

64baf3cfea [CRYPTO]: Added CRYPTO_TFM_REQ_MAY_SLEEP flag
The crypto layer currently uses in_atomic() to determine whether it is
allowed to sleep.  This is incorrect since spin locks don't always cause
in_atomic() to return true.

Instead of that, this patch returns to an earlier idea of a per-tfm flag
which determines whether sleeping is allowed.  Unlike the earlier version,
the default is to not allow sleeping.  This ensures that no existing code
can break.

As usual, this flag may either be set through crypto_alloc_tfm(), or
just before a specific crypto operation.

ff4cc3ac93 [TUNTAP]: Allow setting the linktype of the tap device from userspace
Currently tun/tap only supports the EN10MB ARP type.  For use with
wireless and other networking types it should be possible to set the
ARP type via an ioctl.

Patch v2: Included check that the tap interface is down before changing the
link type out from underneath it

0ca06a00e2 [ALSA] AC97 bus interface for ad-hoc drivers
AC97 Codec,PCI drivers
I've made the review changes and as requested I've pasted the RFC by
Nicolas below:-

'I would like to know what people think of the following patch.  It
allows for a codec on an AC97 bus to be shared with other drivers which
are completely unrelated to audio.  It registers a new bus type, and
whenever a codec instance is created then a device for it is also
registered with the driver model using that bus type.  This allows, for
example, to use the extra features of the UCB1400 like the touchscreen
interface and the additional GPIOs and ADCs available on that chip for
battery monitoring.  I have a working UCB1400 touchscreen driver here
that simply registers with the driver model happily working alongside
with audio features using this.'

Changes over RFC:-

  o Now matches codec name within codec group.
  o Added ac97_dev_release() to stop kernel complaining about no release
method for device.
  o Added 'config SND_AC97_BUS' to sound/pci/Kconfig and moved 'config
SND_AC97_CODEC' out with the PCI=n statement.
  o module is now called snd-ac97-bus
