Regulator: gpio_swtich: Remove gpio_switch regulator driver

The gpio_switch regulator is NV driver developed during
tegra3 bringup time. The driver functionality is upstreamed
to mainline into fixed regulator and it is accepted by community.
The required functionality is also downstream and required client
driver is moved to use the fixed  regulator. Hence this driver
is just duplicating functionality with fixed regulator and hence
removing this.

mfd: max8907c: Do not use I2C_M_NOSTART in first message

It is not recommended to use the flag I2C_M_NOSTART in first

The documentation kernel/Documentation/i2c/i2c-proocol says:
    In a combined transaction, no 'S Addr Wr/Rd [A]' is generated at some
    point. For example, setting I2C_M_NOSTART on the second partial message
    generates something like:
      S Addr Rd [A] [Data] NA Data [A] P
    If you set the I2C_M_NOSTART variable for the first partial message,
    we do not generate Addr, but we do generate the startbit S. This will
    probably confuse all other clients on your bus, so don't try this.

Chaitanya Bandi [Mon, 12 Mar 2012 10:48:07 +0000]
i2c: tegra: Avoid duplicate write into Tx fifo

Dvc I2C_DONE_INTR_EN interrupt bit is always enable into dvc
control register3. During normal transaction on dvc i2c bus
sometimes one transaction written two times in TX fifo buffer
because of triggered dvc interrupt. This is causing to corrupt
the next transaction header and send wrong address over dvc
i2c bus. To solve this issue dvc i2c interrupt has to disable
during filling of Tx fifo and enable after that.

Updated the following things in code:
(1) Add the code to mask/unmask I2C_DONE_INTR_EN into dvc control reg3
writing into Tx Fifo register.
(2) Put delay before resetting the controller

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

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.

JP Abgrall [Mon, 20 Jun 2011 19:41:46 +0000]
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
  and matching stats will show up under the uid with the given

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/
The uid stats are obtainable in ./stats.

Chia-chi Yeh [Fri, 15 Apr 2011 22:22:09 +0000]
net: Reorder incoming packets in PPPoLAC and PPPoPNS.

PPP handles packet loss but does not work with out of order packets.
This change performs reordering of incoming data packets within a
sliding window of one second. Since sequence number is optional,
receiving a packet without it will drop all queued packets.

Currently the logic is triggered by incoming packets, so queued
packets have to wait till another packet is arrived. It is done for
simplicity since no additional locks or threads are required. For
reliable protocols, a retransmission will kick it. For unreliable
protocols, queued packets just seem like packet loss. Time-critical
protocols might be broken, but they never work with queueing anyway.

net: activity_stats: Add statistics for network transmission activity

When enabled, tracks the frequency of network transmissions
(inbound and outbound) and buckets them accordingly.
Buckets are determined by time between network activity.

Each bucket represents the number of network transmisions that were
N sec or longer apart. Where N is defined as 1 << bucket index.

This network pattern tracking is particularly useful for wireless
networks (ie: 3G) where batching network activity closely together
is more power efficient than far apart.

New file: /proc/net/stat/activity


Min Bucket(sec) Count
              1 7
              2 0
              4 1
              8 0
             16 0
             32 2
             64 1
            128 0

staging: android: lowmemorykiller: Fix task_struct leak

As it turns out, the CONFIG_PROFILING interfaces leak a
task struct if the notifier chain returns NOTIFY_OK.. doh.

This patch reworks lowmemkiller to use the new generic task
free notifier chain.

Bluetooth: Use the stored LTK for restabilishing security

Now that it's possible that the exchanged key is present in
the link key list, we may be able to estabilish security with
an already existing key, without need to perform any SMP
