d6014e776c drm/amd/display: remove dummy is_blanked() to optimise boot time 
is_blanked() hook is a dummy one for underlay pipe, hence
when called, it loops for ~300ms at boot.

This patch removes this dummy call and adds missing checks.

3098e5b7ee drm: rcar-du: disable dtc graph-endpoint warnings on DT overlays 
The rcar DT overlays are missing symetrical remote-endpoint properties
in their graph nodes because the remote-endpoint is fixed up at
run-time. Disable the dtc 'graph-endpoint' warnings when compiling these
overlays. If this becomes a common problem for overlays, then perhaps
this check needs to be disabled for all overlays.

444ac87bec Merge tag 'exynos-drm-next-for-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next 
- Add S5PV210 FIMD variant support.

- Add IPP v2 framework.
  . it is a rewritten version of the Exynos mem-to-mem image processing
    framework which supprts color space conversion, image up/down-scaling
    and rotation. This new version replaces existing userspace API with
    new easy-to-use and simple ones so we have already applied the use of
    these API to real user, Tizen Platform[1], and also makes existing
    Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API.

    And below are patch lists we have applied to a real user,
    https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/log/?h=tizen&qt=grep&q=ipp
    https://git.tizen.org/cgit/platform/adaptation/samsung_exynos/libtdm-exynos/commit/?h=tizen&id=b59be207365d10efd489e6f71c8a045b558c44fe
    https://git.tizen.org/cgit/platform/kernel/linux-exynos/log/?h=tizen&qt=grep&q=ipp

    TDM(Tizen Display Manager) is a Display HAL for Tizen platform.
    Ps. Only real user using IPP API is Tizen.

    [1] https://www.tizen.org/

- Two cleanups
  . One is to just remove mode_set callback from MIPI-DSI driver
    because drm_display_mode data is already available from crtc
    atomic state.
  . And other is to just use new return type, vm_fault_t
    for page fault handler.

76ef6b28ea drm: set FMODE_UNSIGNED_OFFSET for drm files 
Since we have the ttm and gem vma managers using a subset
of the file address space for objects, and these start at
0x100000000 they will overflow the new mmap checks.

I've checked all the mmap routines I could see for any
bad behaviour but overall most people use GEM/TTM VMA
managers even the legacy drivers have a hashtable.

cd078bf95d drm/i915/execlists: Use rmb() to order CSB reads 
We assume that the CSB is written using the normal ringbuffer
coherency protocols, as outlined in kernel/events/ring_buffer.c:

    *   (HW)                              (DRIVER)
    *
    *   if (LOAD ->data_tail) {            LOAD ->data_head
    *                      (A)             smp_rmb()       (C)
    *      STORE $data                     LOAD $data
    *      smp_wmb()       (B)             smp_mb()        (D)
    *      STORE ->data_head               STORE ->data_tail
    *   }

So we assume that the HW fulfils its ordering requirements (B), and so
we should use a complimentary rmb (C) to ensure that our read of its
WRITE pointer is completed before we start accessing the data.

The final mb (D) is implied by the uncached mmio we perform to inform
the HW of our READ pointer.

0c591a40af drm/i915: Mark up nested spinlocks 
When we process the outstanding requests upon banning a context, we need
to acquire both the engine and the client's timeline, nesting the locks.
This requires explicit markup as the two timelines are now of the same
class, since commit a89d1f921c ("drm/i915: Split i915_gem_timeline into
individual timelines").

68266f1c08 gpu: drm: qxl: Adding new typedef vm_fault_t 
Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

Reference id -> 1c8f422059 ("mm: change return type to

4db518e4e8 drm/i915/execlists: Relax CSB force-mmio for VT-d 
The original switch to use CSB from the HWSP was plagued by the effect
of read ordering on VT-d; we would read the WRITE pointer from the HWSP
before it had completed writing the CSB contents. The mystery comes down
to the lack of rmb() for correct ordering with respect to the writes
from HW, and with that resolved we can remove the VT-d special casing.

41e403d04e Revert "drm/i915/gvt: set max priority for gvt context" 
This reverts commit 11474e9091.

There are issues which will block the host preemption before, instead of
disabling it use one workaround "setting max priority for gvt context"
to avoid the gvt context be preempted by the host. Now the issues have been
cleared, so revert this patch to enable host preemption.

for LRM, SRM, we cannot get write data in a simple way.
On other side,  the force_to_nonpriv reigsters will only be written in LRI
in current drivers. so we don't want to bother the handler to handle those
memory access cmds, just leave a print message here.

0438a10598 drm/i915/gvt: do not return error on handling force_to_nonpriv registers 
Return error will cause vm hang and enter failsafe mode.
However, we don't want that happen on detecting an wrong force_to_nonpriv
register write.
Therefore, we just omit the wrong write or patch it to default value.

v2: only return 0 on detecting lri write of registers outside whitelist,
but still return error on other error conditions.  (zhenyu wang)

The disable_warn_untrack never prevent gvt from printing untracked
mmio errors. We were disturbed by this error storm and the fix is
just adding them to the list with no essential new change.

This message is only useful for enabling new platform during
developing process. So lower the message level to debug and then
remove disable_warn_untrack.

f79401b477 drm/i915/selftests: scrub 64K 
We write all 4K page entries, even when using 64K pages. In order to
verify that the HW isn't cheating by using the 4K PTE instead of the 64K
PTE, we want to remove all the surplus entries. If the HW skipped the
64K PTE, it will read/write into the scratch page instead - which we
detect as missing results during selftests.
