afe842297f RADEON: fix race in vblank interrupt handling 
It's possible that we disable vblank interrupts and clear the
corresponding flag in irq_enable_reg, but receive an interrupt at just
the wrong time, causing us to not ack it properly, nor report to the
core kernel that it was handled.  Fix that case by always handling
vblank interrupts, even if the irq_enable_reg field is clear.

2d24455ed8 Remove broken CRTC enable checks and incorrect user irq enable in set_pipe 
routine.

d8ed021d29 radeon: VBlank rework fixups. 
Fix range of frame counter registers.

Use DRM_ERR() instead of Linux specific error codes in shared code.

Remove duplicate register definitions and superfluous local variables.

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

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.

1000d88ddf Fix memory leaks in vblank error paths. 
Also use drm_calloc instead of drm_alloc and memset, and use the size of the
struct instead of the size of the pointer for allocation...

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

ca47fa90b7 Update vblank code: 
- move pre/post modeset ioctl to core
  - fixup i915 buffer swap
  - fix outstanding signal count code
  - create new core vblank init routine
  - test (works with glxgears)
  - simplify i915 interrupt handler

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.

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

This reverts commit feb6803778.

This was a bad idea, the macro is actually a bit harder to convert
to a static for the other use cases
