de18a29e0f drm/i915: fix regression due to ba3d8d749b
We don't track gpu flush request in any special way. So even with
obj->write_domain == 0, a gpu flush might be outstanding but no
yet executed. Even worse, the latest request might use the object
only for reading. So and unconditional call to object_wait_rendering
is needed for !pipelined.

Hence revert that patch fully and untangle the flushing from the
synchronization again.

bcf50e2775 drm/i915: Handle pagefaults in execbuffer user relocations
Currently if we hit a pagefault when applying a user relocation for the
execbuffer, we bail and return EFAULT to the application. Instead, we
need to unwind, drop the dev->struct_mutex, copy all the relocation
entries to a vmalloc array (to avoid any potential circular deadlocks
when resolving the pagefault), retake the mutex and then apply the
relocations.  Afterwards, we need to again drop the lock and copy the
vmalloc array back to userspace.

v2: Incorporate feedback from Daniel Vetter.

Under KMS, restoring the cursor is handled upon modeswitch in order to
avoid enabling an undefined set of registers. At the moment, the cursor
is restored before the aperture and modes are fully setup causing some
invalid access during resume, such as:

  PGTBL_ER: 0x00040000
    Invalid GTT entry during Cursor Fetch

Fix this by only performing cursor register save/restore under UMS where
it is done in the correct sequence.

e7dbb2f2f8 drm/i915: Take advantage of auto-polling CRT hotplug detection on PCH hardware
Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough
that we can dispense with the manual force hotplug trigger stuff. This means that
hotplug detection is as simple as reading the current hotplug register values.

The first time the hotplug detection is activated, the code synchronously waits for a hotplug
sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

51311d0a5c drm/i915: Do not hold mutex when faulting in user addresses
Linus Torvalds found that it was rather trivial to trigger a system
freeze:

  In fact, with lockdep, I don't even need to do the sysrq-d thing: it
  shows the bug as it happens. It's the X server taking the same lock
  recursively.

  Here's the problem:

    =============================================
    [ INFO: possible recursive locking detected ]
    2.6.37-rc2-00012-gbdbd01a #7
    ---------------------------------------------
    Xorg/2816 is trying to acquire lock:
     (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e

    but task is already holding lock:
     (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a

    other info that might help us debug this:
    2 locks held by Xorg/2816:
     #0:  (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a
     #1:  (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b

This recursion was introduced by rearranging the locking to avoid the
double locking on the fast path (4f27b5d and fbd5a26d) and the
introduction of the prefault to encourage the fast paths (b5e4f2b). In
order to undo the problem, we rearrange the code to perform the access
validation upfront, attempt to prefault and then fight for control of the
mutex.  the best case scenario where the mutex is uncontended the
prefaulting is not wasted.

A process suspended waiting for a higher sequence or no sequence to unreserve,
a bo may be beaten to the reservation by a process with a lower sequence.
In that case the first process should give up trying to reserve and
