The pcd, pwt, and pat bits on page table entries affect the cpu cache.  Since
the cache is a host resource, the guest should not be able to control it.
Moreover, the meaning of these bits changes depending on whether pat is
enabled or not.

So, force these bits to zero on shadow page table entries at all times.

Eliminate some possibilities for user processes writing to the Gigaset
character device to be left sleeping indefinitely, by adding wakeup calls
to error paths and properly disposing of pending write requests when the
device is disconnected.

It also removes unnecessary NULL checks before usb_free_urb() and
usb_kill_urb() calls.

More fixes to build breakage from the work_struct changes ...  this updates
the tps65010 driver.  Plus, fix some dependencies related to the way it's
used on the OMAP OSK: force static linking there, since the resulting
kernel can't link.

NOTE that until the i2c core gets fixed to work without SMBUS_QUICK,
kernels needing this driver must still use "tps65010.force=0,0x48" on the
command line.
