ef5ab24bd3 vmwgfx: Remove dmabuf check in present ioctl
Doesn't protect any error code and only gets in the way of debugging.

The driver implements the needed resource management required
to use that register.

24bb5a0ce3 vmwgfx: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107

d2c184fb10 vmwgfx: return -EFAULT instead of number of bytes remaining
The intent here was to return an error code, but instead the code
returns the number of bytes remaining (that weren't copied).

5438ae88d0 vmwgfx: Wrap drm_read and drm_poll
Make sure the device is processing the fifo when these functions are
called in case they might sleep waiting for an event.

f63f6a59d3 vmwgfx: Add functionality to get 3D caps
Since we don't allow user-space to map the fifo anymore,
add a parameter to get fifo hw version and
an ioctl to copy the 3D capabilities.

07999a7e0e vmwgfx: Remove the possibility to map the fifo from user-space
This was previously used by user-space to check whether a fence
sequence had passed or not.
With fence objects that's not needed anymore.

f77cef3db3 drm/vmwgfx: Update the user-space interface.
When time-based throttling is implemented, we need to bump minor.
When the old way of detecting scanout is removed, we need to bump major.
In the meantime, this change should not break existing user-space.

fb1d9738ca drm/vmwgfx: Add DRM driver for VMware Virtual GPU
This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
