into drm-fixes
radeon and amdgpu fixes for 4.3. Highlights:
- Move pm sysfs setup later in the driver init process to avoid
problems with laptop scripts attempting to change pm settings
before the driver has finished setting up the pm hardware.
- Fix console restore if a drm app (e.g. X) is forcibly killed
- Flag iceland support as experimental for now
- Misc bug fixes

If amdgpu_ib_get() fails we returned the error code but we missed
freeing ib.

The new amdgpu driver passes a user space pointer in a 64-bit structure
member, which is the correct way to do it, but it attempts to
directly cast it to a __user pointer in the kernel, which causes
a warning in three places:
drm/amd/amdgpu/amdgpu_cs.c: In function 'amdgpu_cs_parser_init':
drm/amd/amdgpu/amdgpu_cs.c:180:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
chunk_array_user = (uint64_t __user *)(cs->in.chunks);
This changes all three to add an intermediate cast to 'unsigned long'
as other drivers do. This avoids the warning and works correctly on
both 32-bit and 64-bit architectures.

These have not been tested very extensively and generally
seem to be problematic. Mark them as experimental for now.

They were added relatively early in the driver init process
which meant that in some cases the driver was not finished
initializing before external tools tried to use them which
could result in a crash depending on the timing.

qxl_bo_unref calls drm_gem_object_unreference_unlocked which
locks dev->struct_mutex. However this lock could be already
locked if the call came from qxl_gem_object_free.
As we don't need to call qxl_bo_ref/qxl_bo_unref cause
qxl_release_list_add will hold a reference by itself avoid
to call them and the possible deadlock.

This avoid a dependency lock error.
According to https://lwn.net/Articles/548909/ users of WW mutex API
should avoid using different context.
When a buffer is reserved with qxl_bo_reserve a ww_mutex_lock without
context is used. However during qxl_draw_dirty_fb different locks
with specific context are used.
This is detected during a machine booting with a debug kernel with lock
dependency checking enabled.
Like many other function in this file to avoid this problem object
pinning is used. Once the object is pinned is not necessary to keep
the lock so it can be released avoiding the locking problem.

Since 9eb1e57f564d4e6e10991402726cc83fe0b9172f
drm/dp/mst: make sure mst_primary mstb is valid in work function
we validate the mstb structs in the work function, and doing
that takes a reference. So we should never get here with the
work function running using the mstb device, only if the work
function hasn't run yet or is running for another mstb.
So we don't need to sync the work here, this was causing
lockdep spew as below.

In order to cache the EDID properly for tiled displays, we
need to retrieve it before we register the connector with
userspace, otherwise userspace can call get resources
and try and get the edid before we've even cached it.
This fixes some problems when hotplugging mst monitors,
with X/mutter running. As mutter seems to get 0 modes
for one of the monitors in the tile.
v2: fix warning in radeon
handle tile setting in cached path rather than
get edid path.

output ports should always have a connector, unless
in the rare case connector allocation fails in the

In this case we only need to teardown the pdt,

send a hotplug msg.
In the case were we add the port to the destroy
list we need to send a hotplug if we destroy
any connectors, so userspace knows to reprobe
stuff.
this patch also handles port->connector allocation
failing which should be a rare event, but makes
the code consistent.

This is unnecessary and it makes it easier to see what is needed
from port.
also add blank line to make things nicer.

called cursor_set2 in addition. Now that the core handles
this, drop this radeon specific version.

If a driver uses the cursor_set2 crtc callback rather than
cursor_set, use that. This fixes the fbdev helper for drivers
that use cursor_set2.

drm_kms_helper_poll_enable() is called from a context in
intel_hpd_irq_storm_disable() where the the mode_config mutex is
already locked.
When this function was converted to lock this mutex in
commit 8c4ccc4ab6f6 ("drm/probe-helper: Grab mode_config.mutex
in poll_init/enable") a deadlock occurred.
Call the newly implemented non-locking version of this function.
Changes since v1:
- use function name suffix '_locked' for the function that
is to be called from a locked context.

A previous commit resets the Context Status Buffer (CSB) read pointer in
ring init
commit c0a03a2e4c4e ("drm/i915: Reset CSB read pointer in ring init")
This is generally correct, but this pointer is not reset after
suspend/resume in some platforms (cht). In this case, the driver should
read the register value instead of resetting the sw read counter to 0.
Otherwise we process old events, leading to unwanted pre-emptions or
something worse.
But in other platforms (bdw) and also during GPU reset or power up, the
CSBWP is reset to 0x7 (an invalid number), and in this case the read
pointer should be set to 5 (the interrupt code will increment this
counter one more time, and will start reading from CSB[0]).
v2: When the CSB registers are reset, the read pointer needs to be set
to 5, otherwise the first write (CSB[0]) won't be read (Mika).
Replace magic numbers with GEN8_CSB_ENTRIES (6) and GEN8_CSB_PTR_MASK
(0x07).

So let's protect this case.
My first attempt was to remove the intel_prepare_ddi, but Daniel had pointed out
this is really needed to restore those registers values. And Imre pointed out
that this case was without the flag protection and this was actually where things
were going bad. So I've just checked and this indeed solves my issue.
The regressing intel_prepare_ddi call was added in

When we're out of command buffer space, we turn on the command buffer
processed irq without re-checking for finished command buffers afterwards.
This might lead to a missed irq and the command submission process waiting
forever for space.
Fix this by rerunning the command buffer submission handler whenever we're
out of command space. This ensures both that we don't needlessly turn on
the irq, and that if we decide to turn on the irq, we recheck for finished
command buffers before going to sleep.

The only thing mode_fixup was doing was set the adjusted_mode->vrefresh to
60, but it already has the value of 60 when the decon_mode_fixup() is
called. That means this call is actually pointless and can be removed.

The only thing mode_fixup was doing was set the adjusted_mode->vrefresh to
60, but it already has the value of 60 when the fimd_mode_fixup() is
called. That means this call is actually pointless and can be removed.

When obj->import_attach is existed, code calling drm_prime_gem_destroy()
was removed from commit 67e93c808b48 ("drm/exynos: stop copying sg
table"), and it's a fault.
The drm_prime_gem_destroy() is cleanup function which GEM drivers need
to call when they use drm_gem_prime_import() to import dma-bufs, so
exynos-drm driver using drm_gem_prime_import() needs calling
drm_prime_gem_destroy().

There is no guarantee that DMA addresses are the same as physical
addresses, but dma_to_pfn() knows how to convert a dma_addr_t to a PFN
which can then be converted to a struct page.
