HID: add support for PenMount HID TouchScreen Driver
This patch adds a seperate hid-penmount driver to work
around an issue with the HID report descriptor. The
descriptor does not contain the ContactID usage and as
result the touchscreen is represented as normal mouse
to the system.
This driver maps the button 0 emitted by the touchscreen
to BTN_TOUCH. This makes it possible to use touch events
in userspace.

HID: thingm: fix workqueue race on remove
thingm_remove_rgb() needs to flush the workqueue after all the LED classes
have been unregistered, otherwise the removal might race with another LED
event coming, causing thingm_led_set() to schedule additional work after
thingm_remove_rgb() has flushed it. This obviously causes oops later, as
the scheduled work has been freed in the meantime.
In addition to that, move the hid_hw_stop() to an earlier place, so that
dmesg is not polluted by failure messages about not being able to write
the LED while the device is being shut down.

HID: usbhid: improve handling of Clear-Halt and reset
This patch changes the way usbhid carries out Clear-Halt and reset.
Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver
immediately restarts the interrupt URB, even if the Clear-Halt failed.
This doesn't work out well when the reason for the failure was that
the device was disconnected (when a low- or full-speed device is
connected through a hub to an EHCI controller, transfer errors caused
by disconnection are reported as stalls by the hub). Instead now the
driver will attempt a reset after a failed Clear-Halt.
The way resets are carried out is also changed. Now the driver will
call usb_queue_reset_device() instead of calling usb_reset_device()
directly. This avoids a deadlock that would arise when a device is
unplugged: The hid_reset() routine runs as a workqueue item, a reset
attempt after the device has been unplugged will fail, failure will
cause usbhid to be unbound, and the disconnect routine will try to do
cancel_work_sync(). The usb_queue_reset_device() implementation is
carefully written to handle scenarios like this one properly.

HID: input: force generic axis to be mapped to their user space axis
Atmel 840B digitizer presents a stylus interface which reports twice
the X coordinate and then twice the Y coordinate. In its current
implementation, hid-input assign the first X to X, then the second to Y,
then the first Y to Z, then the second one to RX.
This is wrong, and X should always be mapped to X, no matter what.
A solution consists in forcing X, Y, Z, RX, RY, RZ to be mapped to their
correct user space counter part.

d40a6898e5 mistakenly caused instructions which are not marked as
EmulateOnUD to be emulated upon #UD exception. The commit caused the check of

result instructions whose emulation is broken may be emulated. This fix moves

kvm: iommu: fix the third parameter of kvm_iommu_put_pages (CVE-2014-3601)
The third parameter of kvm_iommu_put_pages is wrong,
It should be 'gfn - slot->base_gfn'.
By making gfn very large, malicious guest or userspace can cause kvm to
go to this error path, and subsequently to pass a huge value as size.
Alternatively if gfn is small, then pages would be pinned but never
unpinned, causing host memory leak and local DOS.
Passing a reasonable but large value could be the most dangerous case,
because it would unpin a page that should have stayed pinned, and thus
allow the device to DMA into arbitrary memory. However, this cannot
happen because of the condition that can trigger the error:
- out of memory (where you can't allocate even a single page)
should not be possible for the attacker to trigger
- when exceeding the iommu's address space, guest pages after gfn
will also exceed the iommu's address space, and inside
kvm_iommu_put_pages() the iommu_iova_to_phys() will fail. The
page thus would not be unpinned at all.

When a resync/recovery completes the buffer space is freed. But not

This can result in a small memory leak.
There is a subtle side-effect of this bug. When a RAID10 is reshaped
to a larger array (more devices), the reshape is immediately followed
by a "resync" of the new space. This "resync" will use the buffer
space which was allocated for "reshape". This can cause problems

During recovery of a double-degraded RAID6 it is possible for
some blocks not to be recovered properly, leading to corruption.
If a write happens to one block in a stripe that would be written to a

to the other missing device, then that recovered data may not be written.
This patch skips, in the double-degraded case, an optimisation that is

If a stripe in a raid6 array received a write to each data block while
the array is degraded, and if any of these writes to a missing device

In this case the P and Q blocks need to be read so that the part of
the missing block which is *not* being updated by the write can be
constructed. Due to a logic error, these blocks are not loaded, so
the update cannot proceed and the stripe is 'handled' repeatedly in an

When bl_power support got added to asus-wmi, the error handling for it was
written to ignore -ENODEV, to avoid not registering a backlight interface for

At the same time the error handling for brightness_max was modified to do the

register a backlight interface.

ideapad-laptop: Change Lenovo Yoga 2 series rfkill handling
It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=

https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.
And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).
So this patch does 3 things to get proper rfkill handling on these models:
1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.
2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1
3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.
