Drivers where the DRM objects have a lifetime that extends beyond that
of the DRM device need to zero out the DRM object memory to void stale
data such as properties. The DRM core code expects to operate on newly
allocated and zeroed out objects and will behave unexpectedly, such as
add duplicate properties, otherwise.

I was playing with clang and oh surprise! a warning trigerred by
-Wshift-overflow (gcc doesn't have this one):

Turned out GEN6_WIZ_HASHING_MASK was already shifted by 16, and we were
trying to shift it a bit more.
The other thing is that it's not the usual case of setting WA bits here, we
need to have separate mask and value.
To fix this, I've introduced a new _MASKED_FIELD() macro that takes both the
(unshifted) mask and the desired value and the rest of the patch ripples
through from it.

When we unplug a dp mst branch we unreference the entire tree from
the root towards the leaves. Which is ok, since that's the way the
pointers and so also the refcounts go.
But when we drop the reference we must make sure that we remove the
branches/ports from the lists/pointers before dropping the reference.
Otherwise the get_validated functions will still return it instead
of returning NULL (which indicates a potentially on-going unplug).
The mst branch destroy gets this right for ports: First it deletes
the port from the ports list, then it unrefs. But the ports destroy
function gets it wrong: First it unrefs, then it drops the ref. Which
means a zombie mst branch can still be validate with get_validated_mstb_ref
when it shouldn't.
Fix this.
This should address a backtrace Dave dug out somewhere on unplug:

On MST systems the monitors don't appear when we set the fb up,
but plymouth opens the drm device and holds it open while they
come up, when plymouth finishes and lastclose gets called we
don't do the delayed fb probe, so the monitor never appears on the
console.
Fix this by moving the delayed checking into the mode restore.
v2: Daniel suggested that ->delayed_hotplug is set under
the mode_config mutex, so we should check it under that as
well, while we are in the area.

After a bit of irc discussion we've concluded that it would be prudent
to check that callers use the mask/enable paramters correctly. So add
a WARN_ON.
Spurred by Damien's bugfix which added _MASKED_FIELD.
v2: We use WARN_ON(1) a lot to catch default cases in switch blocks
which should always be extended. So this doesn't work really. Dunno
why gcc only started complaining when I've moved the WARN out of the
static inline helper to address a feedback from Jani.

Similar to a patch from Thomas Daniel for lrc contexts. This keeps
both sides somewhat in sync and should make Dave Gordon happy.
Note that both the wa and the golden context init code suffer a bit
from an inssuficient split into driver load and hw init code. Which
means we have a bunch of tests all over the place to check whether the
one-time initialization has been done already or not.
All that one-tim code should be moved into the one-time ring setup
code, but that's work for later.

Added the request structure's 'uniq' identifier to the trace information. Also
renamed the '_complete' trace event to '_notify' as it actually happens in the
IRQ 'notify_ring()' function. The intention is to add a new '_complete' trace
event which occurs when a request structure is actually marked as complete.
However, at the moment the completion status is re-tested every time the query
is made so there isn't a completion event as such.
v2: New patch added to series.
v3: Rebased to remove completion caching as that is apparently contentious.

There is a general theory that kzmalloc is better/safer than kmalloc, especially
for interesting data structures. This change updates the request structure
allocation to be zero filled.
This also fixes crashes in the reset code. Quoting Mika's patch:
"Clean the request structure on alloc. Otherwise we might end up
referencing uninitialized fields. This is apparent when we try to
cleanup the preallocated request on ring reset, before any request has
been submitted to the ring. The request->ctx is foobar and we end up
freeing the foobarness."

The display related patches earlier in this series were edited during merge to
improve the request unreferencing. Specifically, the need for de-referencing at
interrupt time was removed. However, the resulting code did a 'deref(req) ; req
= NULL' sequence rather than using the 'req_assign(req, NULL)' wrapper. The two
are functionally equivalent, but using the wrapper is more consistent with all
the other places where requests are assigned.
Note that the whole point of the wrapper is that using it everywhere that
request pointers are assigned means that the reference counting is done
automatically and can't be accidentally forgotten about. Plus it allows simpler
future maintainance if the reference counting mechanisms ever need to change.

If we extend the commit_plane handlers for each plane type to be able to
handle fb=0, then we can easily implement plane disable via the
update_plane handler. The cursor plane already works this way, and this
is the direction we need to go to integrate with the atomic plane
handler. We can now kill off the type-specific disable functions, as
well as the redundant intel_plane_disable() (not to be confused with
intel_disable_plane()).
Note that prepare_plane_fb() only gets called as part of update_plane
when fb!=NULL (by design, to match the semantics of the atomic plane
helpers); this means that our commit_plane handlers need to handle the
frontbuffer tracking for the disable case, even though they don't handle
it for normal updates.
v2:
- Change BUG_ON to WARN_ON (Ander/Daniel)
v3:
- Drop unnecessary plane->crtc check since a previous patch to plane
update ensures that plane->crtc will always be non-NULL, even for
disable calls that might pass NULL from userspace. (Ander)
- Drop a s/crtc/plane->crtc/ hunk that was unnecessary. (Ander)
v4:
- Fix missing whitespace (Ander)
v5:
- Use state's crtc rather than plane's crtc in
intel_check_primary_plane(). plane->crtc could be NULL, but we've
already fixed up state->crtc to ensure it's non-NULL (even if
userspace passed it as NULL during a disable call). (Ander)

When disabling a plane, it is legal to pass crtc = NULL. Since planes
on Intel hardware are tied to a fixed CRTC, go ahead and set state->crtc
to the appropriate crtc in cases where it is passed to us as NULL.
In a future patch, we will start using the update handler for plane
disables, so this will help ensure we always have a non-NULL crtc
pointer to work with.

The 'prepare' step for all types of planes are pretty similar;
consolidate the three 'prepare' functions into a single function. This
paves the way for future integration with the atomic plane handlers.
Note that we pull the 'wait for pending flips' functionality out of the
primary plane's prepare step and place it directly in the 'setplane'
code. When we move to the atomic plane handlers, this code will be in
the 'atomic begin' step.

Primary and sprite planes have already been refactored to include a
'prepare' step which handles all the commit-time operations that could
fail (i.e., pinning buffers and such). Refactor the cursor commit in a
similar manner.
For simplicity and consistency with other plane types, we also switch to
using intel_pin_and_fence_fb_obj() to perform our pinning for
non-physical cursors. This will allow us to more easily migrate the
code into the atomic 'begin' handler in a plane-agnostic manner in a
future patchset.
v2:
- Update GEM fb tracking for physical cursors too. (Ander)
- Use intel_unpin_fb_obj() rather than
i915_gem_object_unpin_from_display_plane() and do so while holding
struct_mutex. (Ander)
- Update plane->fb in commit_cursor_plane. This isn't really necessary
since the DRM core does this for us in __setplane_internal(), but
doing it in our driver once we know we're going to succeed helps
avoid confusion. (Ander)

After some refactor intel_primary_plane_setplane() does the same
as intel_pipe_set_base() so we can get rid of it and replace the calls
with intel_primary_plane_setplane().
v2: take Ville's comments:
- get the right arguments for update_plane()
- use drm_crtc_get_hv_timing()
v3 (by Matt):
- Rebase to latest di-nightly codebase
- Use primary->funcs->update_plane() in __intel_set_mode()
- Use primary->funcs->disable_plane() in intel_crtc_disable()
v4 (by Matt):
- Drop redundant calls to intel_crtc_wait_for_pending_flips() before
calling update_plane() (Ville)

Merge it into the plane update_plane() callback and make other
users use the update_plane() functions instead.
The fb != crtc->cursor->fb was already inside intel_crtc_cursor_set_obj()
so we fold intel_crtc_cursor_set_obj() inside intel_commit_cursor_plane()
and merge both paths into one.
v5 (by Matt):
- Rebase onto latest di-nightly codebase
- Drop extra unreference call when we fail to pin (Ville)

We need to get hdisplay and vdisplay in a few places so create a
helper to make our job easier.
Note that drm_crtc_check_viewport() and intel_modeset_pipe_config() were
previously making adjustments for doublescan modes and vscan > 1 modes,
which was incorrect. Using our new helper fixes this mistake.
v2 (by Matt): Use new stereo doubling function (suggested by Ville)
v3 (by Matt):
- Add missing kerneldoc (Daniel)
- Use drm_mode_copy() (Jani)
v4 (by Matt):
- Drop stereo doubling function again; add 'stereo only' flag
to drm_mode_set_crtcinfo() instead (Ville)
v5 (by Matt):
- Note behavioral change in drm_crtc_check_viewport() and
intel_modeset_pipe_config(). (Ander)
- Describe new adjustment flags in drm_mode_set_crtcinfo()'s
kerneldoc. (Ander)

This patch checks if the process that opens the /dev/kfd device is 32-bit
process. If so, it returns -EPERM and prints a warning message in dmesg.
This is done to prevent 32-bit user processes from using amdkfd, and hence, HSA
features.
AMD's HSA userspace stack will also support only 64-bit processes on Linux.
