2018-02-01drm/i915: Only attempt to scan the requested number of shrinker slabsChris Wilson
Since commit 4e773c3a8a69 ("drm/i915: Wire up shrinkctl->nr_scanned"), we track the number of objects we scan and do not wish to exceed that as it will overly penalise our own slabs under mempressure. Given that we now know the target number of objects to scan, use that as our guide for deciding to shrink as opposed to the number of objects we manage to shrink (which doesn't correspond to the numbers we report to shrinkctl).

2018-02-01drm/i915/gvt: Keep obj->dma_buf link NULL during exportingTina Zhang
According to commit (319c933c71f3dbdb2b3274d1634d3494c70efa06) Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Aug 15 00:02:46 2013 +0200 drm/prime: proper locking+refcounting for obj->dma_buf link obj->dma_buf link should be reinstated at import time. Gvt-g dma-buf buffer exposeing might be simpler, as there won't be much racing during Gvt-g dma-buf exposing. In other words, Gvt-g dma-buf exposing can guarantee exposing happens before gem close ioctl, and Gvt-g is the only exporter of the guest framebuffer. But following the drm prime scheme can give Gvt-g a chance to increase a dma-buf reference count during importing. Otherwise, we have to increase the reference during exposing, which will break the case that the only reference userspace has held was through the dma-buf fd and the reference count is one.

2018-02-01drm/i915: Try EDID bitbanging on HDMI after failed readStefan Brüns
The ACK/NACK implementation as found in e.g. the G965 has the falling clock edge and the release of the data line after the ACK for the received byte happen at the same time. This is conformant with the I2C specification, which allows a zero hold time, see footnote [3]: "A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the V IH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL." Some HDMI-to-VGA converters apparently fail to adhere to this requirement and latch SDA at the falling clock edge, so instead of an ACK sometimes a NACK is read and the slave (i.e. the EDID ROM) ends the transfer. The bitbanging releases the data line for the ACK only 1/4 bit time after the falling clock edge, so a slave will see the correct value no matter if it samples at the rising or the falling clock edge or in the center. Fallback to bitbanging is already done for the CRT connector.

2018-01-14x86/retpoline: Remove compile time warningThomas Gleixner
Remove the compile time warning when CONFIG_RETPOLINE=y and the compiler does not have retpoline support. Linus rationale for this is: It's wrong because it will just make people turn off RETPOLINE, and the asm updates - and return stack clearing - that are independent of the compiler are likely the most important parts because they are likely the ones easiest to target. And it's annoying because most people won't be able to do anything about it. The number of people building their own compiler? Very small. So if their distro hasn't got a compiler yet (and pretty much nobody does), the warning is just annoying crap. It is already properly reported as part of the sysfs interface. The compile-time warning only encourages bad things.
