commit 09fb8bd1a63b0f9f15e655c4fe8d047e5d2bf67a upstream.
Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.

drm: Introduce an iterator over holes in the drm_mm range manager
helpers and iterators for hole handling have been introduced with some
debug BUG_ONs sprinkled over. Unfortunately this broke the mm dumper
which unconditionally tried to compute the size of the very first
hole.
While at it unify the code a bit with the hole dumping in the loop.
v2: Extract a hole dump helper.

GMBUS based DVO transmitter detection seems to be unreliable which could
result in an unusable DVO port.

commit 054430e773c9a1e26f38e30156eff02dedfffc17 upstream.
Okay so Alan's patch handled the case where there was no registered fbcon,
however the other path entered in set_con2fb_map pit.
In there we called fbcon_takeover, but we also took the console lock in a couple
of places. So push the console lock out to the callers of set_con2fb_map,
this means fbmem and switcheroo needed to take the lock around the fb notifier
entry points that lead to this.
This should fix the efifb regression seen by Maarten.

commit d627b62ff8d4d36761adbcd90ff143d79c94ab22 upstream.
This is rather a hack to fix brightness hotkeys on a Clevo laptop. CADL is not
used anywhere in the driver code at the moment, but it could be used in BIOS as
is the case with the Clevo laptop.
The Clevo B7130 requires the CADL field to contain at least the ID of
the LCD device. If this field is empty, the ACPI methods that are called
on pressing brightness / display switching hotkeys will not trigger a
notification. As a result, it appears as no hotkey has been pressed.

commit c19b3b0f6eed552952845e4ad908dba2113d67b4 upstream.
When KMS has parsed an EDID "detailed timing", it leaves the frame rate
zeroed. Consecutive (debug-) output of that mode thus yields 0 for
vsync. This simple fix also speeds up future invocations of
drm_mode_vrefresh().
While it is debatable whether this qualifies as a -stable fix I'd apply
it for consistency's sake; drm_helper_probe_single_connector_modes()
does the same thing already for all probed modes.

commit 16dad1d743d31a104a849c8944e6b9eb479f6cd7 upstream.
EDID spreads some values across multiple bytes; bit-fiddling is needed
to retrieve these. The current code to parse "detailed timings" has a

See
http://en.wikipedia.org/wiki/EDID
and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why
that needs to be a left shift.

Okay you don't really want to use udl devices as your console, but if
you are unlucky enough to do so, you run into a lot of schedule while atomic
due to printk being called from all sorts of funky places. So check if we
are in an atomic context, and queue the damage for later, the next printk
should cause it to appear. This isn't ideal, but it is simple, and seems to
work okay in my testing here.
(dirty area idea came from xenfb)

commit 83e68189745ad931c2afd45d8ee3303929233e7f upstream.
Originally 'efi_enabled' indicated whether a kernel was booted from
EFI firmware. Over time its semantics have changed, and it now
indicates whether or not we are booted on an EFI machine with
bit-native firmware, e.g. 64-bit kernel with 64-bit firmware.
The immediate motivation for this patch is the bug report at,
https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
which details how running a platform driver on an EFI machine that is
designed to run under BIOS can cause the machine to become
bricked. Also, the following report,
https://bugzilla.kernel.org/show_bug.cgi?id=47121
details how running said driver can also cause Machine Check
Exceptions. Drivers need a new means of detecting whether they're
running on an EFI machine, as sadly the expression,
if (!efi_enabled)
hasn't been a sufficient condition for quite some time.
Users actually want to query 'efi_enabled' for different reasons -
what they really want access to is the list of available EFI
facilities.
For instance, the x86 reboot code needs to know whether it can invoke
the ResetSystem() function provided by the EFI runtime services, while
the ACPI OSL code wants to know whether the EFI config tables were
mapped successfully. There are also checks in some of the platform
driver code to simply see if they're running on an EFI machine (which
would make it a bad idea to do BIOS-y things).
This patch is a prereq for the samsung-laptop fix patch.

If the requested number of DWs on the ring is larger than
the size of the ring itself, return an error.
In testing with large VM updates, we've seen crashes when we
try and allocate more space on the ring than the total size
of the ring without checking.
This prevents the crash but for large VM updates or bo moves
of very large buffers, we will need to break the transaction
down into multiple batches. I have patches to use IBs for
the next kernel.

commit bb588820ef421c6098dca1fec29c3b347f1c8c19 upstream.
Force the crtc mem requests on/off immediately rather
than waiting for the double buffered updates to kick in.
Seems we miss the update in certain conditions. Also
handle the DCE6 case.

the MC before the requests actually stop.

commit e521a29014794d139cca46396d1af8faf1295a26 upstream.
Aruba and newer gpu does not need the avivo cursor work around,
quite the opposite this work around lead to corruption.
agd5f: check DCE6 rather than ARUBA since the issue is DCE
version specific rather than family specific.

commit 262b6d363fcff16359c93bd58c297f961f6e6273 upstream.
In the slow path, we are forced to copy the relocations prior to
acquiring the struct mutex in order to handle pagefaults. We forgo
copying the new offsets back into the relocation entries in order to
prevent a recursive locking bug should we trigger a pagefault whilst
holding the mutex for the reservations of the execbuffer. Therefore, we
need to reset the presumed_offsets just in case the objects are rebound
back into their old locations after relocating for this exexbuffer - if
that were to happen we would assume the relocations were valid and leave
the actual pointers to the kernels dangling, instant hang.
Fixes regression from commit bcf50e2775bbc3101932d8e4ab8c7902aa4163b4

commit 48e858340dae43189a4e55647f6eac736766f828 upstream.
This reverts commit 9756fe38d10b2bf90c81dc4d2f17d5632e135364.
The bogus lvds output is actually a lvds->hdmi bridge, which we don't
really support. But unconditionally disabling it breaks some existing
setups.
