Update the cfg layer with new channel info

The upper layer is not notified of the change in channel after roaming.
This results in AGO creation on incorrect channel (previous AP channel)
after roaming. This change will update the cfg layer with the new channel
info after receiving romaing event.

Revert "lowmemorykiller: zram space available should be accounted"

This reverts commit b0a90d9e2cbca96e755f7e385665f1be97fa9a69.

Processes reciding in memory are much faster than processes
in swap. For better user experience in a multiprocessing
environment it is preferable not to allow too many processes
to recide in memory.

So, do not consider swap_free in other_free.

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.

security: tlk_driver: Pin user space page(s).

Pin user space pages based on the type of memory i.e.

TE_PARAM_TYPE_MEM_RO or TE_PARAM_TYPE_MEM_RW param
indicates whether the TLK kernel will setup a RO/RW
mapping for the TA to this buffer.

Based on the type of memory we should pin the pages

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.

security: tlk_driver: modify secure storage glue

The secure world now sends a PREEMPT_BY_FS error code as a result
of OpenSession/LaunchOp call. This indicates a pending FS request
from the secure world which we need to handle and send the

Until the secure firmware and the linux driver get in sync, we keep
legacy SS handling alive to avoid incomaptibility issues. Once the
secure firmware switches to the new handling, we would remove the
legacy support from the linux driver as well.

This reverts commit 459d61d7fc74baf77408f892a2e14f5457d1a04a.

The reverted patch hacks stacktraces on watchdog resets into the
fiq debugger, making the fiq debugger useless for anything else.

video: tegra: host: initialize vi regulator info

Problem description:
 - nvhost_vi_init also specifies which regulator supplies
   current to VI
 - If this is not called before nvhost_vi_finalize_powerdown,
   nvhost_vi_finalize_powerdown will not initialize the required
   regulator
 - nvhost_vi_init was being called inside nvhost_module_busy.
   nvhost_module_busy is ultimately called as the result
   of userspace operation in most cases, which is unreliable
 - If the userspace ordering changes, nvhost_vi_finalize_powerdown
   is called when there is no regulator set against vi

Fix description:
 - Call nvhost_vi_init as a part of vi_probe
