2018-06-04PCI: shpchp: Fix AMD POGO identificationBjorn Helgaas
The fix for an AMD POGO erratum related to SHPC incorrectly identified the device. The workaround should be applied only for AMD POGO devices, but it was instead applied to: - all AMD bridges, and - all devices from any vendor with device ID 0x7458 Fixes: 53044f357448 ("[PATCH] PCI Hotplug: shpchp: AMD POGO errata fix") Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Rafael J.

2018-06-04igb: Clear TSICR interrupts together with ICRJoanna Yurdal
Issuing "ip link set up/down" can block TSICR interrupts, what results in missing PTP Tx timestamp and no PPS pulse generation. Problem happens when the link is set up with the TSICR interrupts pending. ICR is cleared before enabling interrupts, while TSICR is not. When all TSICR interrupts are pending at this moment, time_sync interrupt will never be generated. TSICR should be cleared as well. In order to reproduce the issue: 1. Setup linux with IEEE 1588 grandmaster and PPS output enabled 2. Continue setting link up/down with random intervals between commands 3. Wait until PPS is not generated ( only one pulse is generated and PPS dies), and ptp4l complains constantly about Tx timeout.

2018-06-04drm/msm: Fix NULL deref on bind/probe deferralSean Paul
This patch avoids dereferencing msm_host->dev when it is NULL. If we find ourselves tearing down dsi before calling (mdp4|mdp5|dpu)_kms_init(), we'll end up in a state where the dev pointer is NULL and trying to extract priv from it will fail. This was introduced in a seemingly innocuous commit to ensure the arguments to msm_gem_put_iova() are correct (even though that function has been a stub for ~5 years).

2018-06-04e1000e: Ignore TSYNCRXCTL when getting I219 clock attributesBenjamin Poirier
There have been multiple reports of crashes that look like kernel: RIP: 0010:[<ffffffff8110303f>] timecounter_read+0xf/0x50 [...] kernel: Call Trace: kernel: [<ffffffffa0806b0f>] e1000e_phc_gettime+0x2f/0x60 [e1000e] kernel: [<ffffffffa0806c5d>] e1000e_systim_overflow_work+0x1d/0x80 [e1000e] kernel: [<ffffffff810992c5>] process_one_work+0x155/0x440 kernel: [<ffffffff81099e16>] worker_thread+0x116/0x4b0 kernel: [<ffffffff8109f422>] kthread+0xd2/0xf0 kernel: [<ffffffff8163184f>] ret_from_fork+0x3f/0x70 These can be traced back to the fact that e1000e_systim_reset() skips the timecounter_init() call if e1000e_get_base_timinca() returns -EINVAL, which leads to a null deref in timecounter_read(). Commit 83129b37ef35 ("e1000e: fix systim issues", v4.2-rc1) reworked e1000e_get_base_timinca() in such a way that it can return -EINVAL for e1000_pch_spt if the SYSCFI bit is not set in TSYNCRXCTL. Some experimentation has shown that on I219 (e1000_pch_spt, "MAC: 12") adapters, the E1000_TSYNCRXCTL_SYSCFI flag is unstable; TSYNCRXCTL reads sometimes don't have the SYSCFI bit set. Retrying the read shortly after finds the bit to be set. This was observed at boot (probe) but also link up and link down. Moreover, the phc (PTP Hardware Clock) seems to operate normally even after reads where SYSCFI=0. Therefore, remove this register read and unconditionally set the clock parameters.

2018-06-04of: platform: stop accessing invalid dev in of_platform_device_destroySrinivas Kandagatla

2018-06-04infiniband: fix a possible use-after-free bugCong Wang
ucma_process_join() will free the new allocated "mc" struct, if there is any error after that, especially the copy_to_user(). But in parallel, ucma_leave_multicast() could find this "mc" through idr_find() before ucma_process_join() frees it, since it is already published. So "mc" could be used in ucma_leave_multicast() after it is been allocated and freed in ucma_process_join(), since we don't refcnt it. Fix this by separating "publish" from ID allocation, so that we can get an ID first and publish it later after copy_to_user().

git://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git into for-next Pull verbs counters series from Leon Romanovsky: ==================== Verbs flow counters support This series comes to allow user space applications to monitor real time traffic activity and events of the verbs objects it manages, e.g.: ibv_qp, ibv_wq, ibv_flow. The API enables generic counters creation and define mapping to association with a verbs object, the current mlx5 driver is using this API for flow counters. With this API, an application can monitor the entire life cycle of object activity, defined here as a static counters attachment. This API also allows dynamic counters monitoring of measurement points for a partial period in the verbs object life cycle. In addition it presents the implementation of the generic counters interface. This will be achieved by extending flow creation by adding a new flow count specification type which allows the user to associate a previously created flow counters using the generic verbs counters interface to the created flow, once associated the user could read statistics by using the read function of the generic counters interface. The API includes: 1. create and destroyed API of a new counters objects 2. read the counters values from HW Note: Attaching API to allow application to define the measurement points per objects is a user space only API and this data is passed to kernel when the counted object (e.g. flow) is created with the counters object. =================== * tag 'verbs_flow_counters': IB/mlx5: Add counters read support IB/mlx5: Add flow counters read support IB/mlx5: Add flow counters binding support IB/mlx5: Add counters create and destroy support IB/uverbs: Add support for flow counters IB/core: Add support for flow counters IB/core: Support passing uhw for create_flow IB/uverbs: Add read counters support IB/core: Introduce counters read verb IB/uverbs: Add create/destroy counters support IB/core: Introduce counters object and its create/destroy IB/uverbs: Add an ib_uobject getter to ioctl() infrastructure net/mlx5: Export flow counter related API net/mlx5: Use flow counter pointer as input to the query function

The XPS 13 9370 doesn't expose the necessary KBD_LED_AC_TOKEN in the BIOS, so the driver thinks it cannot adjust the AC keyboard backlight timeout. This patch adds a quirk to fix this until Dell adds the missing token to the BIOS.

2018-06-04platform/x86: dell-wmi: Ignore new rfkill and fn-lock eventsKai Heng Feng
There are two new events generated by dell-wmi, rfkill and fn-lock, from Dell Systems. When Fn-lock hotkey gets pressed to switch to function mode: [85951.591542] dell_wmi: Unknown key with type 0x0010 and code 0xe035 pressed [85951.591546] dell_wmi: Unknown key with type 0x0010 and code 0x0000 pressed When Fn-lock hotkey gets pressed to switch to multimedia mode: [85956.667686] dell_wmi: Unknown key with type 0x0010 and code 0xe035 pressed [85956.667690] dell_wmi: Unknown key with type 0x0010 and code 0x0001 pressed When radio hotkey gets pressed: [85974.430220] dell_wmi: Unknown key with type 0x0010 and code 0xe008 pressed These events are for notification purpose, so we can ignore them. This patch is tested on XPS 9370.

2018-06-04mmc: renesas_sdhi: really fix WP logic regressionsWolfram Sang
This reverts commit e060d376cc61 ("mmc: renesas_sdhi: fix WP detection") and adds some code to really fix the regressions. It was missed so far that Renesas R-Car instantiations of SDHI chose to disable internal WP and used the existence of "wp-gpios" to en/disable WP at all. With the first refactoring by Yamada-san with commit 2ad1db059b9a ("mmc: renesas_sdhi: use MMC_CAP2_NO_WRITE_PROTECT instead of TMIO own flag"), WP was always disabled even when GPIOs were present. With Wolfram's first fix which gets now reverted, GPIOs were honored. But when not available, the fallback was to internal WP and not to disabled WP. This caused wrong WP status on uSD card slots. Restore the old behaviour now. By default, WP is disabled. When a GPIO is found, the GPIO re-enables WP. We will think about possible better ways to handle this in the future. Tested on a previously regressing Renesas Lager board (H2) and a still working Renesas Salvator-X board (M3-W).

2018-06-04mfd: cros_ec_dev: Don't advertise junk features on failureStephen Boyd
If the feature query fails during this driver's probe, we memset the features bits to 0, but then we continue to overwrite that with whatever junk we read back when the feature probing failed. In the case of a SPI device, it may be complete junk, causing the caller of this function to think certain features are present when they aren't. Don't copy over the bad message on failure so we can fail more gracefully. Fixes: e4244ebddae2 ("platform/chrome: Introduce a new function to check EC features.")

2018-06-04mfd: intel-lpss: Fix Intel Cannon Lake LPSS I2C input clockJarkko Nikula
Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C than Sunrisepoint which uses 120 MHz. Preliminary information was that both share the same clock rate but actual silicon implements elevated rate for better support for 3.4 MHz high-speed I2C. This incorrect input clock rate results too high I2C bus clock in case ACPI doesn't provide tuned I2C timing parameters since I2C host controller driver calculates them from input clock rate. Fix this by using the correct rate. We still share the same 230 ns SDA hold time value than Sunrisepoint.

2018-06-04pinctrl: cherryview: limit Strago DMI workarounds to version 1.0Dmitry Torokhov
As Google/Intel will fix the BIOS/Coreboot issues with hardcoding virtual interrupt numbers for keyboard/touchpad/touchscreen controllers in ACPI tables, they will also update BOARD version number from 1.0 to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ numbers on Strago boards to those that still carry older BIOSes. Note that ideally not BOARD but BIOS version should have been updated. However the BIOS version used by Chrome devices has format of Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as we do not have "less than" match mode for DMI data.
