Added STM sensor hub new device id. Also added this new device
in HID_SENSOR_HUB_ENUM_QUIRK to fix report descriptors.
These devices uses old FW which uses logical 0 as minimum.
In these, HID reports are not using proper collection classes.
So we need to fix report descriptors,for such devices. This
will not have any impact, if the FW uses logical 1 as minimum.

The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID
1a2c:0023 does not seem to be handling the reports initialization very well.
This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel
when connected, and a delay before its initialization. This patch adds the
quirk for this device, which causes the delay to disappear.

Some saitek mice implement a tristate button (for switching button mappings in
the original driver) by keeping one of three (non-physical)
buttons constantly pressed.
This breaks X and probably other userspace software.
This patch implements a quirk for the R.A.T.7 and M.M.O.7, tracking the mode
and generating presses of a single button if it changes. Also the missing
release event is generated instantly.

Some drivers use the first HID report in the list instead of using an
index. In these cases, validation uses ID 0, which was supposed to mean
"first known report". This fixes the problem, which was causing at least
the lgff family of devices to stop working since hid_validate_values
was being called with ID 0, but the devices used single numbered IDs
for their reports:
0x05, 0x01, /* Usage Page (Desktop), */
0x09, 0x05, /* Usage (Gamepad), */
0xA1, 0x01, /* Collection (Application), */
0xA1, 0x02, /* Collection (Logical), */
0x85, 0x01, /* Report ID (1), */

The extra seven bits are only required when allocating the report buffer.
We can not use those extra bytes for the length of the report in the
generic implementation of .request because the device might (will) refuse
the set_report command.
This has been verified on the Atmel touchpad found on the Samsung Ativ 9
plus, which uses hid-multitouch and HID over I2C. Without this fix, the
device refuses to switch to the multitouch mode, and it becomes unresponsive
from the user point of view.
Actually, this has been discussed during the initial submission of the
commit 4fa5a7f76cc7b6ac87f57741edd2b124851d119f, see
https://patchwork.kernel.org/patch/3621751/

The IPMI driver would wake up periodically looking for events and
watchdog pretimeouts. If there is nothing waiting for these events,
it's really kind of pointless to be checking for them. So modify the
driver so the message handler can pass down if it needs the lower layer
to be waiting for these. Modify the system interface lower layer to
turn off all timer and thread activity if the upper layer doesn't need
anything and it is not currently handling messages. And modify the
message handler to not restart the timer if its timer is not needed.
The timers and kthread will still be enabled if:
- the SI interface is handling a message.
- a user has enabled watching for events.
- the IPMI watchdog timer is in use (since it uses pretimeouts).
- the message handler is waiting on a remote response.
- a user has registered to receive commands.
This mostly affects interfaces without interrupts. Interfaces with
interrupts already don't use CPU in the system interface when the
interface is idle.

With recent changes it is possible for the timer handler to detect an
idle interface and not start the timer, but the thread to start an
operation at the same time. The thread will not start the timer in that
instance, resulting in the timer not running.
Instead, move all timer operations under the lock and start the timer in
the thread if it detect non-idle and the timer is not already running.
Moving under locks allows the last timeout to be set in both the thread
and the timer. 'Timer is not running' means that the timer is not
pending and smi_timeout() is not running. So we need a flag to detect
this correctly.
Also fix a few other timeout bugs: setting the last timeout when the
interrupt has to be disabled and the timer started, and setting the last
timeout in check_start_timer_thread possibly racing with the timer

In read_all_bytes, we do

...
for (i = 1; i <= bt->read_count; i++)

If bt->read_data[0] == bt->read_count == 255, we loop infinitely in the
'for' loop. Make 'i' an 'int' instead of 'char' to get rid of the
overflow and finish the loop after 255 iterations every time.

At the moment the "Device Drivers / Graphics support" kernel config page
looks rather messy, with DRM and fbdev driver selections on the same
page, some on the top level Graphics support page, some under their
respective subsystems.
If I'm not mistaken, this is caused by the drivers depending on other
things than DRM or FB, which causes Kconfig to arrange the options in
not-so-neat manner.
Both DRM and FB have a main menuconfig option for the whole DRM or FB
subsystem. Optimally, this would be enough to arrange all DRM and FB
options under the respective subsystem, but for whatever reason this
doesn't work reliably.
This patch adds an explicit submenu for DRM and FB, making it much
clearer which options are related to FB, and which to DRM.

over UDP so we use an internal kernel UDP socket to do the

These tunnels should behave just like other software devices and

Most importantly we want the top-level socket (eg TCP) that created
the traffic to be charged for the SKB memory.
However, once you get into the IP output path, we have code that
assumed that whatever was attached to skb->sk is an IP socket.
To keep the top-level socket being charged for the SKB memory,
whilst satisfying the needs of the IP output path, we now pass in an
explicit 'sk' argument.

In the dst->output() path for ipv4, the code assumes the skb it has to
transmit is attached to an inet socket, specifically via
ip_mc_output() : The sk_mc_loop() test triggers a WARN_ON() when the
provider of the packet is an AF_PACKET socket.
The dst->output() method gets an additional 'struct sock *sk'
parameter. This needs a cascade of changes so that this parameter can
be propagated from vxlan to final consumer.

The user can launch the guest in this sequence:
xl create -p /vm.cfg [launch, but pause it]
xl shutdown latest [sets control/shutdown=poweroff]
xl unpause latest
xl console latest [and see that the guest has completely
ignored the shutdown request]
In reality the guest hasn't ignored it. It registers a watch
and gets a notification that there is value. It then calls
the shutdown_handler which ends up calling orderly_shutdown.
Unfortunately that is so early in the bootup that there
are no user-space. Which means that the orderly_shutdown fails.
But since the force flag was set to false it continues on without
reporting.
What we really want to is to use the force when we are in the
SYSTEM_BOOTING state and not use the 'force' when SYSTEM_RUNNING.
However, if we are in the running state - and the shutdown command
has been given before the user-space has been setup, there is nothing
we can do. Worst yet, we stop ignoring the 'xl shutdown' requests!
As such, the other part of this patch is to only stop ignoring
the 'xl shutdown' when we are truly in the power off sequence.
That means the user can do multiple 'xl shutdown' and we will try
to act on them instead of ignoring them.

The 'read_reply' works with 'process_msg' to read of a reply in XenBus.
'process_msg' is running from within the 'xenbus' thread. Whenever
a message shows up in XenBus it is put on a xs_state.reply_list list
and 'read_reply' picks it up.
The problem is if the backend domain or the xenstored process is killed.
In which case 'xenbus' is still awaiting - and 'read_reply' if called -
stuck forever waiting for the reply_list to have some contents.
This is normally not a problem - as the backend domain can come back
or the xenstored process can be restarted. However if the domain
is in process of being powered off/restarted/halted - there is no
point of waiting on it coming back - as we are effectively being
terminated and should not impede the progress.
This patch solves this problem by checking whether the guest is the
right domain. If it is an initial domain and hurtling towards death -
there is no point of continuing the wait. All other type of guests
continue with their behavior (as Xenstore is expected to still be
running in another domain).

We are flagging the parent IRQ as chained, then we must also
make sure to call the chained_irq_[enter|exit] functions for
things to work smoothly.

The __at86rf230_read_subreg function don't mask and shift register
contents which it should do. This patch adds the necessary masks and
shift operations in this function.
Since we have csma support this can make some trouble on state changes.
Since CSMA support turned on some bits in the TRX_STATUS register that
used to be zero, not masking broke checking of the TRX_STATUS field
after commanding a state change.

The AVDD regulator is only enabled when the RF section is active TX_ON
(PLL_ON) state. Since commit 7dcbd22a97eb0689e6c583ad630ae0e7341e34c1
("ieee802154: ensure that first RF212 state comes from TRX_OFF").
We are in TRX_OFF state at the time at86rf230_hw_init is run.
Note that this test would only fail in case of a severe hardware
malfunction (faulty/shorted power supply, etc.) so it wasn't all that
useful in the first place.
