David Woodhouse 638ebbab54 fix radeon setparam on 32/64 systems, harder. 
Commit 9b01bd5b284bbf519b726b39f1352023cb5e9e69 introduced a
    compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
    to handle the fact that on i386, alignof(uint64_t)==4.

    Unfortunately, this handler was installed for _all_ 64-bit
    architectures, instead of only x86_64 and ia64.  And thus it breaks
    32-bit compatibility on every other arch, where 64-bit integers are
    aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.

    Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
    attributes according to the 32-bit ABI, but for now let's just make the
    compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
    whose 32-bit compat support isn't for i386.  It would be a no-op with
    compat_u64 anyway.

Jesse Barnes 741d1c8031 Remove broken crtc enable checks, radeon does it slightly differently 
(this makes get_vblank_counter return an actual value).

Michel Dänzer 0f5334be2b Remove DRIVER_IRQ_VBL(2). 
If the driver doesn't support vertical blank interrupts, it won't call
drm_vblank_init(), and dev->num_crtcs will be 0.

Also fix an off-by-one test against dev->num_crtcs.

Jesse Barnes b06268294a Comment new vblank routines and fixup several issues: 
- use correct refcount variable in get/put routines
  - extract counter update from drm_vblank_get
  - make signal handling callback per-crtc
  - update interrupt handling logic, drivers should use drm_handle_vblank
  - move wakeup and counter update logic to new drm_handle_vblank routine
  - fixup usage of get/put in light of counter update extraction
  - fix longstanding bug in signal code, update pending counter only
    *after* we're sure we'll setup signal handling

Remove the implicit fence-class mechanism.

Wang Zhenyu 109e2a10f2 Add support for the G33, Q33, and Q35 chipsets. 
These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory.  So, we have the X Server allocate that memory and tell
us the address, instead.

root a4cddc6596 Revert "drm: add new drm_wait_on function to replace macro" 
This reverts commit 6e860d08d0.

As I said not a good plan - this macro will have to stay for now,
trying to do the vbl code with the inline was a bit messy - may need specialised
drm wait on functions

root 8d95f4bd91 Revert "move i915 to new drm_wait_on function" 
This reverts commit feb6803778.
