53efaf562a amdgpu: Set cik/si_support to 1 by default if radeon isn't built
It was required to explicitly set these parameters to 1, even if the
radeon driver isn't built at all, which is not intuitive.

7b8d925d5c drm/amdgpu/gfx9: fix driver reload with KIQ
Drop the KCQ disabling via KIQ.  We disable the MEC shortly
after anyway, so there is no need to wait for all of this.
Doing so seems to leave the MEC in a bad way.

7bc7b7777e drm/amdgpu: Don't call amd_powerplay_destroy() if we don't have powerplay
amd_powerplay_destroy() expects a handle pointing to a struct pp_instance.
On chips without PowerPlay, pp_handle points to a struct amdgpu_device. The
resulting attempt to kfree() fields of the wrong struct ends in fire:

Pull scheduler updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Add the SYSTEM_SCHEDULING bootup state to move various scheduler
     debug checks earlier into the bootup. This turns silent and
     sporadically deadly bugs into nice, deterministic splats. Fix some
     of the splats that triggered. (Thomas Gleixner)

   - A round of restructuring and refactoring of the load-balancing and
     topology code (Peter Zijlstra)

   - Another round of consolidating ~20 of incremental scheduler code
     history: this time in terms of wait-queue nomenclature. (I didn't
     get much feedback on these renaming patches, and we can still
     easily change any names I might have misplaced, so if anyone hates
     a new name, please holler and I'll fix it.) (Ingo Molnar)

   - sched/numa improvements, fixes and updates (Rik van Riel)

   - Another round of x86/tsc scheduler clock code improvements, in hope
     of making it more robust (Peter Zijlstra)

   - Improve NOHZ behavior (Frederic Weisbecker)

   - Deadline scheduler improvements and fixes (Luca Abeni, Daniel
     Bristot de Oliveira)

   - Simplify and optimize the topology setup code (Lauro Ramos
     Venancio)

   - Debloat and decouple scheduler code some more (Nicolas Pitre)

   - Simplify code by making better use of llist primitives (Byungchul
     Park)

   - ... plus other fixes and improvements"

81e3e04489 UUID/GUID updates:
- introduce the new uuid_t/guid_t types that are going to replace
    the somewhat confusing uuid_be/uuid_le types and make the terminology
    fit the various specs, as well as the userspace libuuid library.
    (me, based on a previous version from Amir)
  - consolidated generic uuid/guid helper functions lifted from XFS
    and libnvdimm (Amir and me)
  - conversions to the new types and helpers (Amir, Andy and me)

  them. Note that various other subsystems have pulled in this tree, so
  I'd like it to go in early.

  UUID/GUID summary:

   - introduce the new uuid_t/guid_t types that are going to replace the
     somewhat confusing uuid_be/uuid_le types and make the terminology
     fit the various specs, as well as the userspace libuuid library.
     (me, based on a previous version from Amir)

   - consolidated generic uuid/guid helper functions lifted from XFS and
     libnvdimm (Amir and me)

   - conversions to the new types and helpers (Amir, Andy and me)"

2347728934 drm/i915/cfl: Fix Workarounds.
During the review of Coffee Lake workarounds Mika pointed out
that WaDisableKillLogic and GEN9_DISABLE_OCL_OOB_SUPPRESS_LOGIC
should be removed from CFL and with that I should carry the rv-b.

However when doing the v2 I removed another Workaround that should
remain because although not mentioned by spec the history of hangs
around it advocates on its favor.

On some follow-up patches I continued operating on the wrong
workardound, but Ville noticed that, so here is the fix for the
current CFL code that is upstream already.

4ec654bf3a drm/i915: Avoid undefined behaviour of "u32 >> 32"
When computing a hash for looking up relocation target handles in an
execbuf, we start with a large size for the hashtable and proceed to
halve it until the allocation succeeds. The final attempt is with an
order of 0 (i.e. a single element). This means that we then pass bits=0
to hash_32() which then computes "hash >> (32 - 0)" to lookup the single
element. Right shifting a value by the width of the operand is
undefined, so limit the smallest hash table we use to order 1.

v2: Keep the retry allocation flag for the final pass

ce3f7163e4 drm/i915: Disable MSI for all pre-gen5
We have pretty clear evidence that MSIs are getting lost on g4x and
somehow the interrupt logic doesn't seem to recover from that state
even if we try hard to clear the IIR.

Disabling IER around the normal IIR clearing in the irq handler isn't
sufficient to avoid this, so the problem really seems to be further
up the interrupt chain. This should guarantee that there's always
an edge if any IIR bits are set after the interrupt handler is done,
which should normally guarantee that the CPU interrupt is generated.
That approach seems to work perfectly on VLV/CHV, but apparently
not on g4x.

MSI is documented to be broken on 965gm at least. The chipset spec
says MSI is defeatured because interrupts can be delayed or lost,
which fits well with what we're seeing on g4x. Previously we've
already disabled GMBUS interrupts on g4x because somehow GMBUS
manages to raise legacy interrupts even when MSI is enabled.

Since there's such widespread MSI breakahge all over in the pre-gen5
land let's just give up on MSI on these platforms.

Seqno reporting might be negatively affected by this since the legcy
interrupts aren't guaranteed to be ordered with the seqno writes,
whereas MSI interrupts may be? But an occasioanlly missed seqno
seems like a small price to pay for generally working interrupts.

5938628c51 drm/radeon: make MacBook Pro d3_delay quirk more generic
The PCI Power Management Spec, r1.2, sec 5.6.1, requires a 10 millisecond
delay when powering on a device, i.e., transitioning from state D3hot to
D0.

Apparently some devices require more time, and d1f9809ed131 ("drm/radeon:
add quirk for d3 delay during switcheroo poweron for apple macbooks") added
an additional delay for the Radeon device in a MacBook Pro.  4807c5a8a0c8
("drm/radeon: add a PX quirk list") made the affected device more explicit.

Add a generic PCI quirk to increase the d3_delay.  This means we will use
the additional delay for *all* wakeups from D3, not just those initiated by
radeon_switcheroo_set_state().

Pull drm fixes from Dave Airlie:
 "This is the final set of fixes for -rc8, just a few i915 and one
  vmwgfx ones.

  I'm off on holidays for a week, so if anything shows up for fixes I've
  asked Daniel or Sean Paul to herd it in the right direction"

[ The additional etnaviv fixes were already herded towards me as seen in
  my previous pull - Linus ]

Pull drm/etnaviv fixes from Lucas Stach:
 "I realized I just missed the cut-off point for the final drm fixes
  pull, but I have 2 more etnaviv fixes that need to go into 4.12, as
  they fix fallout from the explicit sync work introduced in the last
  merge window"

7204e97685 drm: adv7511_audio: Add .get_dai_id callback to map port number to dai id
ALSA SoC needs to know connected DAI ID for probing. Using
the new audio-card-graph approach, ports/endpoints are used
to describe how the links are connected. Unfortunately, since
ports/endpoints are used as well for video linkages, there
are some issues mixing the port ids to the two (video and
audio) namespaces.

To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.

The will assume that HDMI audio out will be connected to
reg = <2>. This will then be remapped to the ALSA SoC side will
as DAI 0. Allowing the adv7511's hdmi audio support to be used
with the audio-card-graph.

Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c
was what this was mostly copy-pasted from.

e3839bd6f5 drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoC
ALSA SoC needs to know connected DAI ID for probing.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.
dw-hdmi-i2s will assume that HDMI sound will be connected
to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0

	ports {
		#address-cells = <1>;
		#size-cells = <0>;
		port@0 {
			reg = <0>;
			/* HDMI Video IN */
		};
		port@1 {
			reg = <1>;
			/* HDMI OUT */
		};
		port@2 {
			reg = <2>;
			/* HDMI Sound IN */
		};
	};

426ef1bb40 drm/etnaviv: Fix implicit/explicit sync sense inversion
We were reading the no-implicit sync flag the wrong way around,
synchronizing too much for the explicit case, and not at all for the
implicit case. Oops.
