2015-01-01myri10ge: fix error return codeJulia Lawall
Return a negative error code on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> The patch also modifies the test of mgp->cmd to satisfy checkpatch.

Although it doesn't explicitly say so, commit 60ffa478759f39a2 ("e100: Fix MDIO/MDIO-X") appears to be intended to revert the earlier commit 648951451e6d2d53 ("e100: fixed e100 MDI/MDI-X issues"). However, careful examination reveals that the attempted revert actually _inverted_ the test for eeprom_mdix_enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal management updates from Zhang Rui: "First of all, the most important change is the thermal cpu cooling fixes. The major fix here is to have proper sequencing between cpufreq layer and thermal cpu cooling registration. A take away of this fix is an improvement in the thermal drivers code. Thermal drivers that require cpu cooling do not need to check for cpufreq layer. The requirement now is to propagate the error code, if any, while registering cpu cooling device. Thanks to Viresh for implementing the required CPUfreq changes. Second, a new driver is introduced for int340x processor thermal device. Given that int340x thermal is disabled by default, and this processor thermal device is only available on limited platforms, plus the driver does nothing but exposes some thermal limitation information for user space to use, thus I think it is safe to include it in this pull request after missing 3.19-rc2.

2014-12-26net: Generalize ndo_gso_check to ndo_features_checkJesse Gross
GSO isn't the only offload feature with restrictions that potentially can't be expressed with the current features mechanism. Checksum is another although it's a general issue that could in theory apply to anything. Even if it may be possible to implement these restrictions in other ways, it can result in duplicate code or inefficient per-packet behavior. This generalizes ndo_gso_check so that drivers can remove any features that don't make sense for a given packet, similar to netif_skb_features(). It also converts existing driver restrictions to the new format, completing the work that was done to support tunnel protocols since the issues apply to checksums as well. By actually removing features from the set that are used to do offloading, it solves another problem with the existing interface. In these cases, GSO would run with the original set of features and not do anything because it appears that segmentation is not required.

Use generic config_init callback also for KSZ8021 and KSZ8031. This has been avoided this far due to commit b838b4aced99 ("phy/micrel: KSZ8031RNL RMII clock reconfiguration bug"), which claims that the PHY becomes unresponsive if the broadcast-disable flag is set before configuring the clock mode. Turns out that the problem seemingly worked-around by the above mentioned commit was really due to a hardware-configuration issue, where the PHY was in fact strapped to address 3 rather than 0.

The Int340x thermal provides a processor thermal device, which is used to control processor thermal states. These devices are either reported as a PCI device or an ACPI device. This device provides power limits, control states and optional temperature. This change implements minimal requirements to expose processor power limits which can be used during thermal power limiting. Power limits are exposed via an attribute group called "power_limits" under the device. The exported attributes are: power_limit_0_max_uw power_limit_1_max_uw power_limit_0_min_uw power_limit_1_min_uw power_limit_0_tmin_us power_limit_1_tmin_us power_limit_0_tmax_us power_limit_1_tmax_us power_limit_0_step_uw power_limit_1_step_uw Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

git://people.freedesktop.org/~tagr/linux into drm-fixes drm/tegra: Fixes for v3.19-rc1 This is a set of fixes for two regressions and one bug in the IOMMU mapping code. It turns out that all of these issues turn up primarily on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers that aren't multiples of the page size. I happened to be testing HDMI with 1080p while writing the code and framebuffers for that happen to fit exactly within 2025 pages of 4 KiB each. One of the regressions is caused by the IOMMU code allocating pages from shmem which can have associated cache lines. If the pages aren't flushed then these cache lines may be flushed later on and cause framebuffer corruption. I'm not sure why I didn't see this before. Perhaps the board that I was using had enough RAM so that the pages shmem would hand out had a better chance of being unused. Or maybe I didn't look too closely. The fix for this is to fake up an SG table so that it can be passed to the DMA API. Ideally this would use drm_clflush_*(), but implementing that for ARM causes DRM to fail to build as a module since some of the low-level cache maintenance functions aren't exported. Hopefully we can get a suitable API exported on ARM for the next release. The second regression is caused by a mismatch between the hardware pipe number and the CRTC's DRM index. These were used inconsistently, which could cause one code location to call drm_vblank_get() with a different pipe than the corresponding drm_vblank_put(), thereby causing the reference count to become unbalanced. Alexandre also reported a possible race condition related to this, which this series also fixes. * tag 'drm/tegra/for-3.19-rc1-fixes' of git://people.freedesktop.org/~tagr/linux: drm/tegra: dc: Select root window for event dispatch drm/tegra: gem: Use the proper size for GEM objects drm/tegra: gem: Flush buffer objects upon allocation drm/tegra: dc: Fix a potential race on page-flip completion drm/tegra: dc: Consistently use the same pipe drm/irq: Add drm_crtc_vblank_count() drm/irq: Add drm_crtc_handle_vblank() drm/irq: Add drm_crtc_send_vblank_event()

git://anongit.freedesktop.org/drm-intel into drm-fixes Yeah a pull for one patch is a bit overkill but I started to assemble the various patches for 3.20 in a branch for atomic props/ioctl and didn't realize that this bugfix here at the beginnning of the branch should be in 3.19 (because msm is using the helpers arleady). So if you'd merge we'd have it twice or or I need to shuffle branches again. Can do if you want. * tag 'topic/atomic-fixes-2014-12-17' of git://anongit.freedesktop.org/drm-intel: drm/atomic: fix potential null ptr on plane enable

2014-12-22nouveau: bring back legacy mmap handlerDave Airlie
nouveau userspace back at 1.0.1 used to call the X server DRIOpenDRMMaster interface even for DRI2 (doh!), this attempts to map the sarea and fails if it can't. Since 884c6dabb0eafe7227f099c9e78e514191efaf13 from Daniel, this fails, but only ancient drivers would see it. Revert the nouveau bits of that fix.

2014-12-22caif: Fix napi poll list corruptionHerbert Xu
The commit d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt masking in NAPI) breaks caif. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers caif tries to do a last-ditch check and if there is more work it will call napi_schedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in caif.

iowrite32() will byteswap it's argument on big endian archs. iowrite32be() will byteswap on little endian archs. Since we don't want to do this unnecessary byteswap on the fast path, doorbell is stored in the NIC's native endianness. Using the right iowrite() according to the arch endianness.
