[PATCH v5 00/11] A collection of cleanups, revisited

[Dave Gordon <david.s.gordon@intel.com>]

Various things can go wrong during initialisation and teardown, but they
usually don't, so the error-handling paths go largely untested.  This
collection of patches fixes some things I recently noticed. Some might
lead to a kernel OOPS, but mostly they're leaks and other inconsistencies.

Includes Nick Hoath's patch to swap context/engine teardown, because that
helps make setup & teardown more consistent too; but more importantly, that
patch [10/11] is dependent on patch [9/11] of this set to work correctly.
Applying [10/11] without at least [9/11] as well may cause a fault on
driver unload!

v2:
    Patches reordered and the previous [1/4] split into [4..6/6],
    so that the bugs that it's fixing are more clearly visible
    (Mika Kuoppala, although he said it wasn't actually *necessary*).

v3:
    Patches reordered again; the bug fixes are now in patches 3 and 5.
    The former could stand alone; the latter depends on patch 4 and is
    a prerequisite for Nick's patch [6/6] to function.

v4:
    Rebased

v5:
    Patches repartitioned, reordered, and rebased again.
    The first two are now the ones that have already been reviewed
    (R-b: Chris Wilson), the remaining ones have been broken up
    into smaller more digestible chunks.

Dave Gordon (9):
  drm/i915: unmap the correct page in intel_logical_ring_cleanup()
  drm/i915: consolidate LRC mode HWSP setup & teardown
  drm/i915: remove useless copypasted code
  drm/i915: tidy up initialisation failure paths (GEM)
  drm/i915: tidy initialisation failure paths (legacy, part 1)
  drm/i915: tidy initialisation failure paths (legacy, part 2)
  drm/i915: tidy initialisation failure paths (legacy, part 3)
  drm/i915: tear down hardware status page mappings earlier
  drm/i915: make LRC status page teardown code a bit more robust

Nick Hoath (2):
  drm/i915: two small moves towards more consistency
  drm/i915: interchange context/engine cleanup order
