trace: power: add trace_clock_set_parent

Adds a new trace event to be called from clk_set_parent.  Some
cpufreq drivers, including Tegra, reparent the cpu clock to a
slower clock while the main pll is relocking, tracing
clk_set_parent allows traces to show how for long the cpu is
running slower.

Uses a separate TRACE_EVENT instead of the clock event class to
allow the event to contain string names for the child and the
parent.

netfilter: xt_qtaguid: start tracking iface rx/tx at low level

qtaguid tracks the device stats by monitoring when it goes up and down,
then it gets the dev_stats().
But devs don't correctly report stats (either they don't count headers
symmetrically between rx/tx, or they count internal control messages).

Now qtaguid counts the rx/tx bytes/packets during raw:prerouting and
mangle:postrouting (nat is not available in ipv6).

The results are in
  /proc/net/xt_qtaguid/iface_stat_fmt
which outputs a format line (bash expansion):
  ifname  total_skb_{rx,tx}_{bytes,packets}

Added event counters for pre/post handling.
Added extra ctrl_*() pid/uid debugging.

USB accessory mode allows users to connect USB host hardware
specifically designed for Android-powered devices. The accessories
must adhere to the Android accessory protocol outlined in the
http://accessories.android.com documentation. This allows
Android devices that cannot act as a USB host to still interact with
USB hardware. When an Android device is in USB accessory mode, the
attached Android USB accessory acts as the host, provides power
to the USB bus, and enumerates connected devices.

usb: gadget: Add Android Composite Gadget driver

The Android Gadget driver is a composite driver that allows
userspace to change at runtime the list of functions enabled in
its configuration and to configure these functions. It supports
multiple functions: acm, adb, rndis, mtp/ptp, mass storage and
accessory.

It is usually controlled by a daemon that changes the configuration
based on user settings. For example, rndis is enabled when the user
enables sharing the phone data connection and adb (Android Debug
Bridge) is only enabled when the user wants to debug applications
for security reasons.

As an example on how to use it, the following shell commands will
make the gadget disconnect from the host and make it be re-enumerated
as a composite with 1 rndis and 2 acm interfaces, and a different
product id:

echo 0       > /sys/class/android_usb/android0/enable
echo rndis,acm > /sys/class/android_usb/android0/functions
echo 2       > /sys/class/android_usb/android0/f_acm/instances
echo 2d01    > /sys/class/android_usb/android0/idProduct
echo 1       > /sys/class/android_usb/android0/enable

The driver requires a gadget controller that supports software
control of the D+ pullup and the controller driver must support
disabling the pullup during composite_bind.

netfilter: fixup the quota2, and enable.

The xt_quota2 came from

It needed tweaking for it to compile within the kernel tree.
Fixed kmalloc() and create_proc_entry() invocations within
 a non-interruptible context.
Removed useless copying of current quota back to the iptable's
struct matchinfo:
  - those are per CPU: they will change randomly based on which
    cpu gets to update the value.
  - they prevent matching a rule: e.g.
      -A chain -m quota2 --name q1 --quota 123
     can't be followed by
      -D chain -m quota2 --name q1 --quota 123
    as the 123 will be compared to the struct matchinfo's quota member.
Use the NETLINK NETLINK_NFLOG family to log a single message
when the quota limit is reached.
It uses the same packet type as ipt_ULOG, but
 - never copies skb data,
 - uses 112 as the event number (ULOG's +1)
It doesn't log if the module param "event_num" is 0.

netfilter: add xt_qtaguid matching module

This module allows tracking stats at the socket level for given UIDs.
It replaces xt_owner.
If the --uid-owner is not specified, it will just count stats based on
who the skb belongs to. This will even happen on incoming skbs as it
looks into the skb via xt_socket magic to see who owns it.
If an skb is lost, it will be assigned to uid=0.

To control what sockets of what UIDs are tagged by what, one uses:
  echo t $sock_fd $accounting_tag $the_billed_uid \
     > /proc/net/xt_qtaguid/ctrl
 So whenever an skb belongs to a sock_fd, it will be accounted against
   $the_billed_uid
  and matching stats will show up under the uid with the given
   $accounting_tag.

Because the number of allocations for the stats structs is not that big:
  ~500 apps * 32 per app
we'll just do it atomic. This avoids walking lists many times, and
the fancy worker thread handling. Slabs will grow when needed later.

It use netdevice and inetaddr notifications instead of hooks in the core dev
code to track when a device comes and goes. This removes the need for
exposed iface_stat.h.

Put procfs dirs in /proc/net/xt_qtaguid/
  ctrl
  stats
  iface_stat/<iface>/...
The uid stats are obtainable in ./stats.
