Send both fingers using the new multitouch protocol in addition to
the old single finger event and second finger ABS_HAT* hack.
The new protocol does not specify how to report up events. To make
sure the user-space frameworks can generate up events, we send at
least one event where ABS_MT_TOUCH_MAJOR is zero before we stop
sending events for a finger.

This driver allows userspace to receive notification when client
specified key combinations are pressed.
The client opens /dev/keychord and writes a list of keychords
for the driver to monitor.
The client then reads or polls /dev/keychord for notifications.
A client specified ID for the keychord is returned from read()
when a keychord press is detected.

This is needed to support devices that put non-keyboard buttons in
the keyboard matrix. For instance several devices put the trackball
button in the keyboard matrix. In this case BTN_MOUSE should be
reported from the same input device as REL_X/Y.
It is also useful for devices that have multiple logical keyboard in
the same matrix. The HTC dream has a menu key on the external keyboard
and another menu key on the slide-out keyboard. With a single input
device only one of these menu keys can be mapped to KEY_MENU.

Add a family of knobs to /sys/kernel/ipv4 for controlling the TCP window size:
tcp_wmem_min
tcp_wmem_def
tcp_wmem_max
tcp_rmem_min
tcp_rmem_def
tcp_rmem_max
This six values mirror the sysctl knobs in /proc/sys/net/ipv4/tcp_wmem and
/proc/sys/net/ipv4/tcp_rmem.
Sysfs, unlike sysctl, allows us to set and manage the files' permissions and
owners.

net: ipv4: Fix race in tcp_v4_nuke_addr().
To fix a recursive deadlock in 2.6.29, we stopped holding the hash table lock
across tcp_done() calls. This fixed the deadlock, but introduced a race where
the socket could die or change state.
Fix: Before unlocking the hash table, we grab a reference to the socket. We
can then unlock the hash table without risk of the socket going away. We then
lock the socket, which is safe because it is pinned. We can then call
tcp_done() without recursive deadlock and without race. Upon return, we unlock
the socket and then unpin it, killing it.

ipv4: Move sk_error_report inside bh_lock_sock in tcp_v4_nuke_addr
When sk_error_report is called, it wakes up the user-space thread, which then
calls tcp_close. When the tcp_close is interrupted by the tcp_v4_nuke_addr
ioctl thread running tcp_done, it leaks 392 bytes and triggers a WARN_ON.
This patch moves the call to sk_error_report inside the bh_lock_sock, which
matches the locking used in tcp_v4_err.
