Prevents the

These should be functionally equivalent to the older per/post modeset
functions, except that they block out drm_vblank_get right away.
There's only the clock adjusting code (outside of pageflips) in
readone which uses drm_vblank_get. But that code doesn't synchronize
against concurrent modesets and instead handles any such races by
waiting for the right vblank to arrive with a short timetout.
The longer-term plan here is to switch all kms drivers to
drm_vblank_on/off so that common code like pending event cleanup can
be done there, while drm_vblank_pre/post_modeset will be purely
drm internal for the old UMS ioctl.
Note that with this patch Michel uncovered a bug in the dri3
implementation of the DDX (it does vblank waits when the pipe is off),
which had to be fixed first.

On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register
controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS
function.
This is different for GPU's with a single CRTC but a primary and a
TV DAC: here it controls the single CRTC no matter where it is routed.
Therefore we set it here. This avoids an elaborate on/off state tracking
since both primary_dac_dpms() and tv_dac_dpms() functions would have
to touch this bit.
On single CRTC GPUs with just one DAC it's irrelevant where this bit
is handled.

Some devices such as the radeon chips receive information from user
space which needs to be saved when executing an atomic mode set
operation, else the user space would have to be queried again for the
information.
This patch extends the mode_set_base_atomic() call to pass an argument
to indicate if this is an entry or an exit from an atomic kernel mode
set change. Individual drm drivers can properly save and restore
state accordingly.

Get rid of _location and use _start/_end also simplify the
computation of vram_start|end & gtt_start|end. For R1XX-R2XX
we place VRAM at the same address of PCI aperture, those GPU
shouldn't have much memory and seems to behave better when
setup that way. For R3XX and newer we place VRAM at 0. For
R6XX-R7XX AGP we place VRAM before or after AGP aperture this
might limit to limit the VRAM size but it's very unlikely.
For IGP we don't change the VRAM placement.

PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710
