dacb650f12 Input: tsc2005 - do not rearm timer in hardirq handler
We will most likely rearm it yet again the IRQ thread so doing it here
is pointless.

80cc2f0c92 Input: tsc2005 - don't use work for 'pen up' handling
We do not need process context to send input events so let's switch to
a regular timer. I am going to get rid of taking ts->mutex in
tsc2005_irq_thread() later.

9a6e180af7 Input: tsc2005 - do not use 0 in place of NULL
Sparse in unhappy when people use 0 instead of NULL for pointers so
let's rework the way we initialize spi_transfer structure in
tsc2005_cmd() and tsc2005_write().

We need to make sure we have time/work initialized before requesting and

8c3c283e6b Input: xen-kbdfront - advertise either absolute or relative coordinates
A virtualized display device is usually viewed with the vncviewer
application, either by 'xm vnc domU' or with vncviewer localhost:port.
vncviewer and the RFB protocol provides absolute coordinates to the
virtual display. These coordinates are either passed through to a PV
guest or converted to relative coordinates for a HVM guest.

A PV guest receives these coordinates and passes them to the kernels
evdev driver. There it can be picked up by applications such as the
xorg-input drivers. Using absolute coordinates avoids issues such as
guest mouse pointer not tracking host mouse pointer due to wrong mouse
acceleration settings in the guests X display.

Advertise either absolute or relative coordinates to the input system
and the evdev driver, depending on what dom0 provides. The xorg-input
driver prefers relative coordinates even if a devices provides both.
