commit 121a6a17439b000b9699c3fa876636db20fa4107 upstream.
Explicitly set 1024x768 as default mode, so the display doesn't come up
with the largest supported mode.
While being at it drop first three drm_add_modes_noedid calls. As
drm_add_modes_noedid fills the mode list with modes from the database
*up to* the specified size it is pretty pointless to call it multiple
times with different sizes.

commit c683f427bdc43525f61e26609d34e799e7ea4c12 upstream.
Currently drm_pick_cmdline_mode() doesn't care about the interlace
when the given mode line has no "i" suffix. That is, when there are
multiple entries for the same resolution, an interlace mode might be
picked up just depending on the assigned order, and there is no way to
exclude it.
This patch changes the logic for the mode selection, to prefer the
noninterlace mode unless the interlace mode is explicitly given.
When no matching mode is found, it still tries the interlace mode as
fallback.

commit a4945f9522d27e1e6d64a02ad055e83768cb0896 upstream.
The PIPEA quirk is specifically for the issue with the PIPEB PLL on
830gm being slaved to the PIPEA PLL, and so to use PIPEB requires PIPEA
running. i845 doesn't even have the second PLL or pipe, and enabling
the quirk results in a blank DVO LVDS.

This patch enhances the type safety for the kfifo API. It is now safe
to put const data into a non const FIFO and the API will now generate a
compiler warning when reading from the fifo where the destination
address is pointing to a const variable.
As a side effect the kfifo_put() does now expect the value of an element
instead a pointer to the element. This was suggested Russell King. It
make the handling of the kfifo_put easier since there is no need to
create a helper variable for getting the address of a pointer or to pass
integers of different sizes.
IMHO the API break is okay, since there are currently only six users of
kfifo_put().
The code is also cleaner by kicking out the "if (0)" expressions.

commit d0ce7b8567ae76b8a6c0eb8361d121deb98c1b3f upstream.
Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux
switching.") broke the build on non-x86 architectures due to the new
dependency on MXM and MXM being an x86 platform driver.
It built previously since the vga switcheroo registration routines were
zereod out on !X86. The code was built in but unused.
This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO,
allowing it to build on non-x86 and shrinking the module size as well.

commit 0f4706d2740f2a221cd502922b22e522009041d9 upstream.
We have reports of heavy screen corruption if we try to use the stolen
memory reserved by the BIOS whilst the DMA-Remapper is active. This
quirk may be only specific to a few machines or BIOSes, but first lets
apply the big hammer and always disable use of stolen memory when DMAR
is active.
v2 by Jani: Rebase on -fixes, only look at intel_iommu_gfx_mapped.

commit 07ae78c9798b79bad3d3adf983c94ba23fde54d4 upstream.
We always stop the rings when disabling the engines so just
call the stop functions directly from the sdma enable function.
This way the rings' status is set correctly on suspend so
there are no problems on resume. Fixes resume failures that
result in acceleration getting disabled.

commit 14eedc32a3c0ec9dd70448a73763ee21feae3111 upstream.
Without this, a bo may get created in the cpu-inaccessible vram.
Before the CP engines get setup, all copies are done via cpu memcpy.
This means that the cpu tries to read from inaccessible memory, fails,
and the radeon module proceeds to disable acceleration.
Doing this has no downsides, as the real VRAM size gets set as soon as the
CP engines get init.
This is a candidate for 3.14 fixes.

commit a7f1c1e65b68e1e1ab70898528d5977ed68a0a7d upstream.
Commit 0a0afd282f ("drm/nv50-/disp: move DP link training to core and
train from supervisor") added code that uses the wrong register for
computing the display bpp, used for bandwidth calculation. Adjust to use
the same register as used by exec_clkcmp and nv50_disp_intr_unk20_2_dp.

commit 7d3428cd4b2ad51af86fdbdf8284ca38fa95e601 upstream.
Since commit 0fa9061ae8c ("drm/nouveau/mc: handle irq-related setup
ourselves"), drm_device->irq_enabled remained unset. This is needed in
order to properly wait for a vblank event in the generic drm code.
