tegra-se: Unregister algs support from tegra-se

Owing to lower perf, prefer CPU over SE HW for crypto
operations. However, we may still need SE for save/restore
key context across Lp0 so keep the driver to do this.

security: tlk_driver: new ss protocol support

The new secure storage protocol design allows the tlk daemon
to exchange data directly with the secure storage TA.

The only role the tlk_driver now plays is in the scheduling path
between the tlk daemon and the secure storage TA.

A summary of the corresponding changes:

 * add support for persistent mem buffer parameter type (the
   mapping to these buffers persist for the duration of the
   session); persistent mem buffers are kept on a separate
   shared memory descriptor list and are tracked by session id

 * modified ioctl interface between tlk daemon and tlk_driver to
   involve only a single command; the integer value passed down
   by the tlk daemon indicates whether it is ready for a new
   request or has just completed the last request

 * fixed up various warnings

Note that support for old protocol will be left intact until the
corresponding changes are applied to the TLK components.

Revert "security: tlk_driver: delete te_pin_user_pages() and its usage"

We are reverting this as we want to add support of
te_pin_user_pages(). TA can have dynamic mappings
created as part of an OpenSession or LaunchOperation
command.

If either of these specify a buffer as an argument
(with virt addr and length as params), the TLK kernel
will create a mapping to it. This happens for things
that go between TAs (no pin issue there) and between
the NS and S worlds.

In the case of NS buffers being passed in, we need
phys memory to stay where it is, because the secure
world has a mapping to it that Linux is unaware of,
which is why we pin it.

staging: ozwpan: Cancel hrtimer before expiry set

Currently oz_timer_add sets the new expiry time before calling
hrtimer_start_expires where the timer is actually updated in the
timerqueue.

However, this update to expiry time is racy because the the
hrtimer_set_expires call is being performed from a softirq or a thread's
context. The CPU could recieve a hrtimer_interrupt before the
hrtimer_start_expires call but after hrtimer_set_expires.

This would leave the hrtimer with a new expiry value but with the same
position in the rbtree which a subsequent hrtimer_interrupt could use
to perform its timerqueue add/del operations with. Leaving the rbtree
in this stale/bad state causes some timers to never get serviced.

Fix this by first removing the timer from the timerqueue by calling
hrtimer_cancel and then updating the expiry time.

net: wireless: bcmdhd: delete p2p device if already exist

Solution: while registering p2p device(it will only call when

instead of returning failure.

In kernel 3.10 we only use one net device wlan0 and p2p is a
wireless device register above wlan0 (driver_param with with
p2p_device=1). In this specific configuration, the DRIVER STOP
command implies to unregister of the p2p-dev-wlan0 wireless

command occurs only the wlan0 net device is up, the p2p-dev-wlan0
wireless device is never registered again.

Solution:
wl_cfgp2p_del_disc_if code in wl_cfgp2p_down is unnecessary
because the function is called during  unloading driver.
