In current code we register/unregister connector object by
drm_sysfs_connector_add/remove function.

However under some cases, we need to dynamically register or unregister device
multiple times, so we have to go through register -> unregister ->register
routine.

Because after device_unregister function our memory is dirty, we need to do
clean operation in order to re-register the device, otherwise the system
will crash.  The patch intends to clean device after device release.

  x86, setup: guard against pre-ACPI 3 e820 code not updating %ecx

Commit 64ef8957 ("qeth: remove EDDP")
removed the qeth_core_offl.[hc] files, but ended up doing so by just
patching them to zero size, rather than removing them properly.

Actually remove the files.

This fixes all the tiling problems with the 2d ddx. glxgears still doesn't work.
Changes:

- fix a copy&paste error in i8xx fence reg setup. It resulted in an at most a
  512KB offset of the fence reg window, so was only visible sometimes.
- add tests for stride and object size constrains (also for i915 and 1965 class
  hw). Userspace seems to have an of-by-one bug there, which changes the fence
  size by at most 512KB due to an overflow.
- because i8xx hw is quite old (and therefore not as well-tested) I left 2 debug
  WARN_ONs in the i8xx fence reg setup code to hopefully catch any further
  overflows in the bit-fields. Lastly there's one small change to make the
  alignment checks more consistent.
