2014-01-30drm/nouveau: resume display if any later suspend bits failIlia Mirkin
If either idling channels or suspending the fence were to fail, the display would never be resumed. Also if a client fails, resume the fence (not functionally important, but it would potentially leak memory).

2014-01-30drm/nv50: fill in crtc mode struct members from crtc_mode_fixupBen Skeggs
The DRM uses the adjusted mode to calculate constants for vblank timestamping. Our encoder mode_fixup (usually) replaces this data with our backend mode information, which doesn't have the needed data filled in already.

2014-01-29drm/radeon/dce8: workaround for atom BlankCrtc tableAlex Deucher
Some DCE8 boards have a funky BlankCrtc table that results in a timeout when trying to blank the display. The timeout is harmless (all operations needed from the table are complete), but wastes time and is confusing to users so work around it. bug: https://bugs.freedesktop.org/show_bug.cgi?id=73420 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

2014-01-29drm/radeon: set si_notify_smc_display_change properlyAlex Deucher
This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c. Forcing a display active when there is none causes problems with dpm on some SI boards which results in improperly initialized dpm state and boot failures on some boards. As for the bug commit 4573388c92ee tried to address, one can manually force the state to high for better performance when using the card as a headless compute node until a better fix is developed. bugs: https://bugs.freedesktop.org/show_bug.cgi?id=73788 https://bugs.freedesktop.org/show_bug.cgi?id=69395 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> cc: stable@vger.kernel.org

2014-01-29drm/radeon: clean up active vram sizingAlex Deucher
If we are not able to properly initialize one of the gpu engines for buffer paging, we limit vram to the size of the cpu visible aperture. We generally either use the gfx or dma engine to do this. Clean up the size limiting code to only adjust the size based on what ring is selected for buffer paging rather than making assumptions about which engine is selected for paging.

First of all, we should not touch the GPIOs. They are not for selecting the capture source, but they seems just enable the whole audio input curcuit.

2014-01-29ALSA: oxygen: Xonar DG(X): use headphone volume controlRoman Volkov
I tried both variants: volume control and impedance selector. In the first case one minus is that we can't change the volume of multichannel output without additional software volume control. However, I am using this variant for the last three months and this seems good. All multichannel speaker systems have internal amplifier with the volume control included, but not all headphones have this regulator. In the second case, my software volume control does not save the value after reboot. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

Add the new SPI write and read functions. The SPI read function is used for creating initial registers dump and may be used for debugging purposes. SPI operations are cached, so there is a new function to manage the cache (shadow).

When the user switches the output from stereo to multichannel or vice versa, the driver needs to update the channel routing.

2014-01-29x86, kvm: correctly access the KVM_CPUID_FEATURES leaf at 0x40000101Paolo Bonzini
When Hyper-V hypervisor leaves are present, KVM must relocate its own leaves at 0x40000100, because Windows does not look for Hyper-V leaves at indices other than 0x40000000. In this case, the KVM features are at 0x40000101, but the old code would always look at 0x40000001. Fix by using kvm_cpuid_base(). This also requires making the function non-inline, since kvm_cpuid_base() is static.

2014-01-29ALSA: hda - Add parameter for dumping processing coefficientsDavid Henningsson
Processing coefficients are often a vital part of the codec's configuration, so dumping them can be important. However, because they are undocumented and secret, we do not want to enable this for all codecs by default. Therefore instead add this as a debugging parameter. I have prepared for codecs that want to enable this by default by the extra dump_coef bitfield, but unsure if we want to do that as long as the (unlikely, but still) race remains.

2014-01-29Btrfs: setup inode location during btrfs_init_inode_lockedChris Mason
We have a race during inode init because the BTRFS_I(inode)->location is setup after the inode hash table lock is dropped. btrfs_find_actor uses the location field, so our search might not find an existing inode in the hash table if we race with the inode init code. This commit changes things to setup the location field sooner. Also the find actor now uses only the location objectid to match inodes. For inode hashing, we just need a unique and stable test, it doesn't have to reflect the inode numbers we show to userland. Signed-off-by: Chris Mason <clm@fb.com> CC: stable@vger.kernel.org
