Merge tag 'vmwgfx-fixes-3.14-2014-02-05' of git://people.freedesktop.org/~thomash/linux into drm-next

A couple of vmwgfx fixes together with missing bits of legacy device
emulation to facilitate old user-space drivers on new devices.

The shader emulation bits are a bit large, but since they mostly touch the
new device code, regressions are unlikely. I figure the gain of having
this from the start clearly outweighs the risc of adding these bits at
this point.

When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.

This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.

Makes suspend and hibernate now also work with legacy user-space drivers on
guest-backed devices.

GB aware mesa userspace drivers are detected by the fact that they are

Pull parisc updates from Helge Deller:
 "The three major changes in this patchset is a implementation for
  flexible userspace memory maps, cache-flushing fixes (again), and a
  long-discussed ABI change to make EWOULDBLOCK the same value as
  EAGAIN.

  parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
  to keep HP-UX compatibility.  Since we will probably never implement
  full HP-UX support, we prefer to drop this compatibility to make it
  easier for us with Linux userspace programs which mostly never checked
  for both values.  We don't expect major fall-outs because of this
  change, and if we face some, we will simply rebuild the necessary
  applications in the debian archives"
