2015-11-19cpufreq: intel_pstate: Add separate support for Airmont coresPhilippe Longepe
There are two flavors of Atom cores to be supported by intel_pstate, Silvermont and Airmont, so make the driver distinguish between them by adding separate frequency tables. Separate the CPU defaults params for each of them and match the CPU IDs against them as appropriate.

2015-11-19cpufreq: intel_pstate: Replace BYT with ATOMPhilippe Longepe
Rename symbol and function names starting with "BYT" or "byt" to start with "ATOM" or "atom", respectively, so as to make it clear that they may apply to Atom in general and not just to Baytrail (the goal is to support several Atoms architectures eventually). This should not lead to any functional changes.

2015-11-19Revert "cpufreq: intel_pstate: Use ACPI perf configuration"Rafael J. Wysocki
Revert commit 37afb0003242 (cpufreq: intel_pstate: Use ACPI perf configuration) that is reported to cause a regression to happen on a system where invalid data are returned by the ACPI _PSS object. Since that commit makes assumptions regarding the _PSS output correctness that may turn out to be overly optimistic in general, there is a concern that it may introduce regression on more systems, so it's better to revert it now and we'll revisit the underlying issue in the next cycle with a more robust solution.

the commit cdf3464e6c6b ("ipv6: Fix dst_entry refcnt bugs in ip6_tunnel") introduced percpu storage for ip6_tunnel dst cache, but while clearing such cache it used raw_cpu_ptr to walk the per cpu entries, so cached dst on non current cpu are not actually reset.

ssh://ra.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First set of IIO fixes for the 4.4 cycle. This set does not include those for issues introduced during the merge window. Fixes of those will follow in a future series. * ad5064 - Make sure the local i2c_write returns 0 on success rather than the number of bytes transfered. Otherwise we report an error on all writes. - Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on these parts. * ad7793 - The product ID on the datasheet is wrong. Fix it in the driver. * IIO_DUMMY_EVGEN - select IRQ_WORK as a dependency. * lpc32xx - make sure clock is prepared before enabling. * si7020 - data byte order was reversed. Fix it. * vf610 - Internal temperature calculation was wrong if a different reference voltage was used. Now use a linear interpolation function to make it work over the full range. - Fix a division by zero in the case of a device tree property not being present (same issue two fixes). * xilinx XADC - VREFN scale was wrong - fix it.

This patch adds the PCI device ID (0xe0a1) and alx_pci_tbl entry for the Killer E2400 Ethernet controller, modeled after the Killer E2200 controller support (0xe091) already present in the alx driver. This patch was originally authored by Ben Pope, but it got held up by issues in the commit message, so I'm resubmitting it on his behalf. I've extensively used a kernel with this patch on a System76 serw9 laptop and am quite confident it works well (at least on the hardware I have available for testing). Note that as a favor to System76, Ubuntu has been carrying this as a sauce patch in their 4.2 based Wily kernel, which presumably has given it real-world testing on other E2400 equipped hardware (I don't know of any Ubuntu kernel bugs filed about it): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1498633 Signed-off-by: Jason Gerard DeRose <jason@system76.com> Signed-off-by: Ben Pope <benpope81@gmail.com> Signed-off-by: David S.

2015-11-18drm/i915/ddi: fix intel_display_port_aux_power_domain() after HDMI detectImre Deak
Due to the current sharing of the DDI encoder between DP and HDMI connectors we can run the DP detection after the HDMI detection has already set the shared encoder's type. For now solve this keeping the current behavior and running the detection in this case too. For a proper solution Ville suggested to split the encoder into an HDMI and DP one, that can be done as a follow-up.

2015-11-18ASoC: Change the PCM runtime array to a listMengdong Lin
Currently the number of DAI links is statically defined by the machine driver at build time using an array. This makes it difficult to shrink/ grow the number of DAI links at runtime in order to reflect any changes in topology. We can change the DAI link array in the core to a list so that PCMs and FE DAI links can be added and deleted at runtime to reflect changes in use case and DSP topology. The machine driver can still register DAI links as an array. As the 1st step, this patch change the PCM runtime array to a list. A new PCM runtime is added to the list when a DAI link is bound successfully. Later patches will further implement the DAI link list. More: - define snd_soc_new/free_pcm_runtime() to create/free a runtime. - define soc_add_pcm_runtime() to add a runtime to the rtd list. - define soc_remove_pcm_runtimes() to clean up the runtime list. - traverse the rtd list to probe the link components and dais. - Add a field "num" to PCM runtime struct, used to specify the device number when creating the pcm device, and for a soc card to access its dai_props array. - The following 3rd party machine/platform drivers iterate the rtd list to check the runtimes: sound/soc/intel/atom/sst-mfld-platform-pcm.c sound/soc/intel/boards/cht_bsw_rt5645.c sound/soc/intel/boards/cht_bsw_rt5672.c sound/soc/intel/boards/cht_bsw_max98090_ti.c Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-11-18arm64: barriers: fix smp_load_acquire to work with const argumentsWill Deacon
A newly introduced function in include/net/sock.h passes a const argument to smp_load_acquire: static inline int sk_state_load(const struct sock *sk) { return smp_load_acquire(&sk->sk_state); } This cause an allmodconfig build failure, since our underlying load-acquire implementation does not handle const types correctly: include/net/sock.h: In function 'sk_state_load': ./arch/arm64/include/asm/barrier.h:71:3: error: read-only variable '___p1' used as 'asm' output asm volatile ("ldarb %w0, %1" \ This patch fixes the problem by reusing the trick in READ_ONCE that loads via a non-const member of an anonymous union. This has the advantage of allowing us to use smp_load_acquire on packed structures (e.g. arch_spinlock_t) as well as primitive types.

2015-11-18ASoC: s3c24xx-i2s: pass DMA channels as platform dataArnd Bergmann
This is a minor cleanup to make the s3c2412-i2s and s3c24xx-i2s drivers independent of the mach/dma.h header file and to allow removing the dependency on the specific dmaengine driver in the next patch. As a side not, only the s3c24xx-i2s driver seems to still be used, while the definition of the s3c2412-i2s platform device was removed in commit 6d259a25b56d ("ARM: SAMSUNG: use static declaration when it is not used in other files") after it had never been referenced since its introduction in f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). Apparently it should have been used by mach-jive.c, but that never happened. My patch at this point leaves the current state unchanged, we can decide whether to fix or delete the jive driver and s3c2412-i2s another time.

2015-11-18ASoC: samsung: pass DMA channels as pointersArnd Bergmann
ARM64 allmodconfig produces a bunch of warnings when building the samsung ASoC code: sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data': sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] playback_data->filter_data = (void *)playback->channel; sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] capture_data->filter_data = (void *)capture->channel; We could easily shut up the warning by adding an intermediate cast, but there is a bigger underlying problem: The use of IORESOURCE_DMA to pass data from platform code to device drivers is dubious to start with, as what we really want is a pointer that can be passed into a filter function. Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.
