commit b0616c5306b342ceca07044dbc4f917d95c4f825 upstream.

Otherwise we'll have backtraces in assert_panel_unlocked because the
BIOS locks the register. In the reporter's case this regression was
introduced in

<title>drm/i915: More cautious with pch fifo underruns</title>

<content type='text'>
commit b68362278af94e1171f5be9d4e44988601fb0439 upstream.

Apparently PCH fifo underruns are tricky, we have plenty reports that
we see the occasional underrun (especially at boot-up).

So for a change let's see what happens when we don't re-enable pch
fifo underrun reporting when the pipe is disabled. This means that the
kernel can't catch pch fifo underruns when they happen (except when
all pipes are on on the pch). But we'll still catch underruns when
disabling the pipe again. So not a terrible reduction in test
coverage.

Since the DRM_ERROR is new and hence a regression plan B would be to
revert it back to a debug output. Which would be a lot worse than this
hack for underrun test coverage in the wild. See the referenced
discussions for more.

    Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009

It has helped me to add a NULL pointer check that was suggested at
http://lists.freedesktop.org/archives/dri-devel/2014-October/070663.html

I am not familiar with the code. But the change looks sane
and we need something fast at this stage of 3.18 development.

It has helped me to add a NULL pointer check that was suggested at
http://lists.freedesktop.org/archives/dri-devel/2014-October/070663.html

I am not familiar with the code. But the change looks sane
and we need something fast at this stage of 3.18 development.

<title>gpu/radeon: Set flag to indicate broken 64-bit MSI</title>

commit 91ed6fd2c383bb8f02d66e98b4a4d2f7207249dc upstream.

Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.

This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.

This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

Adding Alex's review tag. Patch to the driver is identical to the
reviewed one, I dropped the arch/powerpc hunk rewrote the subject
and cset comment.

commit 8efe82ca908400785253c8f0dfcf301e6bd93488 upstream.

The power management code calls into the display code for
certain things.  If certain power management sysfs attributes
are called before the driver has finished initializing all of
the hardware we can run into problems with uninitialized
modesetting state.  Add a check to make sure modesetting
init has completed to the bandwidth update callbacks to
fix this.  Can be triggered by the tlp and laptop start
up scripts depending on the timing.

commit 9a72384d86b26cb8a2b25106677e1197f606668f upstream.

When screen objects are enabled, the bpp is assumed to be 32, otherwise
it is set to 16.

v2:
* Use u32 instead of u64 for assumed_bpp.
* Fixed mechanism to check for screen objects
* Limit the back buffer size to VRAM.
