[git pull] drm fixes

Hi Linus,

Please pull the 'drm-next' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-next

This contains some fixes since the kms code got merged, one reported
regression, and updates the kms driver to work on a few machines that
needed a different object for cursor use.

I suspect we have at least one more kms fixup coming, with a locking
cleanup and ref count on certain objects needs fixing.

drm/i915: lock correct mutex around object unreference.

This makes sure the mutex is held around the unreference.

drm/i915: add support for physical memory objects

This is an initial patch to do support for objects which needs physical
contiguous main ram, cursors and overlay registers on older chipsets.

These objects are bound on cursor bin, like pinning, and we copy
the data to/from the backing store object into the real one on attach/detach.

possible over the top in attach/detach operations.
no overlay support yet.

drm/i915: make LVDS fixed mode a preferred mode

The detected fixed panel mode really is preferred, so mark it as such and
add it to the LVDS connector mode list.

drm: initial KMS config fixes

When mode setting is first initialized, the driver will call into
drm_helper_initial_config() to set up an initial output and framebuffer
configuration. This routine is responsible for probing the available
connectors, encoders, and crtcs, looking for modes and putting together
something reasonable (where reasonable is defined as "allows kernel
messages to be visible on as many displays as possible").

However, the code was a bit too aggressive in setting default modes when
none were found on a given connector. Even if some connectors had modes,
any connectors found lacking modes would have the default 800x600 mode added
to their mode list, which in some cases could cause problems later down the
line. In my case, the LVDS was perfectly available, but the initial config
code added 800x600 modes to both of the detected but unavailable HDMI
connectors (which are on my non-existent docking station). This ended up
preventing later code from setting a mode on my LVDS, which is bad.

This patch fixes that behavior by making the initial config code walk
through the connectors first, counting the available modes, before it decides
to add any default modes to a possibly connected output. It also fixes the
logic in drm_target_preferred() that was causing zeroed out modes to be set
as the preferred mode for a given connector, even if no modes were available.

drm/i915: set vblank enabled flag correctly across IRQ install/uninstall

In the absence of kernel mode setting, many drivers disable IRQs across VT
switch. The core DRM vblank code is missing a check for this case however;
even after IRQ disable, the vblank code will still have the vblank_enabled
flag set, so unless we track the fact that they're disabled at IRQ uninstall
time, when we VT switch back in we won't actually re-enable them, which means
any apps waiting on vblank before the switch will hang.

This patch does that and also adds a sanity check to the wait condition to
look for the irq_enabled flag in general, as well as adding a wakeup to the
IRQ uninstall path.

Fixes fdo bug #18879 with compiz hangs at VT switch.

drm/i915: don't enable vblanks on disabled pipes

In some cases userland may be confused and try to wait on vblank events from
pipes that aren't actually enabled. We shouldn't allow this, so return
-EINVAL if the pipe isn't on.
