On non-developer devices kgdb prevents CONFIG_PANIC_TIMEOUT from
rebooting the device after a panic. Add module parameters
debug_core.break_on_exception and debug_core.break_on_panic to
allow skipping debug on panics and exceptions respectively. Both
default to true to preserve existing behavior.

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.

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.

For systems that set a common speed for all CPUs, checking current
speed here could bypass the intermediate hispeed bump decision for
this CPU when another CPU was already at hispeed. This could
result in an overly high setting (for all CPUs) in situations
where all CPUs were about to drop to load levels that map to
hispeed or below.

When adb is enabled, only connect the gadget when adbd is ready. If adbd
dies or is restarted (e.g. "adb root"), the gadget is disconnected when
the adb device is close, and it is re-connected once adb re-open the
device.
- Add callbacks to adb, similar to FunctionFs callbacks, to notify the
gadget when the daemon is ready or closed.
- Refcount calls to android_enable/android_disable to enable the gadget
only once all the function daemons are ready.
- Add enable/disble to android_usb_function to notify the function when
it is added/removed from the list of enabled functions.

Fix setting up consoles on multiple fiq debugger devices by
splitting the tty driver init into the initcall, and initializing
the single tty device during probe. Has the side effect of moving
the tty device node to /dev/ttyFIQx, where x is the platform device
id, which should normally match the serial port.
To avoid having to pass a different console=/dev/ttyFIQx for every
device, make the fiq debugger a preferred console that will be used
by default if no console was passed on the command line.

Adds polling tty ops to the fiq debugger console tty, which allows
kgdb to run against an fiq debugger console.
Add a check in do_sysrq to prevent enabling kgdb from the fiq
debugger unless a flag (writable only by root) has been set. This
should make it safe to enable KGDB on a production device.
Also add a shortcut to enable the console and kgdb together, to
allow kgdb to be enabled when the shell on the console is not
responding.

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.

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.
