2020-10-05mmc: sdhci-acpi: AMDI0040: Set SDHCI_QUIRK2_PRESET_VALUE_BROKENRaul E Rangel
This change fixes HS400 tuning for devices with invalid presets. SDHCI presets are not currently used for eMMC HS/HS200/HS400, but are used for DDR52. The HS400 retuning sequence is: HS400->DDR52->HS->HS200->Perform Tuning->HS->HS400 This means that when HS400 tuning happens, we transition through DDR52 for a very brief period. This causes presets to be enabled unintentionally and stay enabled when transitioning back to HS200 or HS400. Some firmware has invalid presets, so we end up with driver strengths that can cause I/O problems.

dma_alloc_coherent() is called with a fixed SZ_2M size, but frees happen with IOAT_CHUNK_SIZE. Recently, IOAT_CHUNK_SIZE was reduced to 512M but the allocation did not change. To fix, change to using the IOAT_CHUNK_SIZE define. This was caught with the upcoming patchset for converting Intel platforms to the dma-iommu implementation. It has a warning when the unmapped size differs from the mapped size.

2020-10-04net: team: fix memory leak in __team_options_registerAnant Thazhemadam
The variable "i" isn't initialized back correctly after the first loop under the label inst_rollback gets executed. The value of "i" is assigned to be option_count - 1, and the ensuing loop (under alloc_rollback) begins by initializing i--. Thus, the value of i when the loop begins execution will now become i = option_count - 2. Thus, when kfree(dst_opts[i]) is called in the second loop in this order, (i.e., inst_rollback followed by alloc_rollback), dst_optsp[option_count - 2] is the first element freed, and dst_opts[option_count - 1] does not get freed, and thus, a memory leak is caused. This memory leak can be fixed, by assigning i = option_count (instead of option_count - 1).

2020-10-04hwmon: (bt1-pvt) Test sensor power supply on probeSerge Semin
Baikal-T1 PVT sensor has got a dedicated power supply domain (feed up by the external GPVT/VPVT_18 pins). In case if it isn't powered up, the registers will be accessible, but the sensor conversion just won't happen. Due to that an attempt to read data from any PVT sensor will cause the task hanging up. For instance that will happen if XP11 jumper isn't installed on the Baikal-T1-based BFK3.1 board. Let's at least test whether the conversion work on the device probe procedure. By doing so will make sure that the PVT sensor is powered up at least at boot time.

2020-10-04hwmon: Add hwmon driver for Intel MAX 10 BMCXu Yilun
This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC chip connects to a set of sensor chips to monitor current, voltage, thermal and power of different components on board. The BMC firmware is responsible for sensor data sampling and recording in shared registers. Host driver reads the sensor data from these shared registers and exposes them to users as hwmon interfaces.

2020-10-04vhost-vdpa: fix page pinning leakage in error pathSi-Wei Liu
Pinned pages are not properly accounted particularly when mapping error occurs on IOTLB update. Clean up dangling pinned pages for the error path. As the inflight pinned pages, specifically for memory region that strides across multiple chunks, would need more than one free page for book keeping and accounting. For simplicity, pin pages for all memory in the IOVA range in one go rather than have multiple pin_user_pages calls to make up the entire region. This way it's easier to track and account the pages already mapped, particularly for clean-up in the error path.

2020-10-04vhost: Don't call log_access_ok() when using IOTLBGreg Kurz
When the IOTLB device is enabled, the log_guest_addr that is passed by userspace to the VHOST_SET_VRING_ADDR ioctl, and which is then written to vq->log_addr, is a GIOVA. All writes to this address are translated by log_user() to writes to an HVA, and then ultimately logged through the corresponding GPAs in log_write_hva(). No logging will ever occur with vq->log_addr in this case. It is thus wrong to pass vq->log_addr and log_guest_addr to log_access_vq() which assumes they are actual GPAs. Introduce a new vq_log_used_access_ok() helper that only checks accesses to the log for the used structure when there isn't an IOTLB device around.

2020-10-04vhost: Don't call access_ok() when using IOTLBGreg Kurz
When the IOTLB device is enabled, the vring addresses we get from userspace are GIOVAs. It is thus wrong to pass them down to access_ok() which only takes HVAs. Access validation is done at prefetch time with IOTLB. Teach vq_access_ok() about that by moving the (vq->iotlb) check from vhost_vq_access_ok() to vq_access_ok(). This prevents vhost_vring_set_addr() to fail when verifying the accesses. No behavior change for vhost_vq_access_ok().

2020-10-03net: stmmac: Modify configuration method of EEE timersVineetha G. Jaya Kumaran
Ethtool manual stated that the tx-timer is the "the amount of time the device should stay in idle mode prior to asserting its Tx LPI". The previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW timer duration which is not correct. Hence, this patch fixes the "ethtool --set-eee tx-timer" to configure the EEE LPI timer. The LPI TW Timer will be using the defined default value instead of "ethtool --set-eee tx-timer" which follows the EEE LS timer implementation. Changelog V2 *Not removing/modifying the eee_timer. *EEE LPI timer can be configured through ethtool and also the eee_timer module param. *EEE TW Timer will be configured with default value only, not able to be configured through ethtool or module param. This follows the implementation of the EEE LS Timer. Fixes: d765955d2ae0 ("stmmac: add the Energy Efficient Ethernet support") Signed-off-by: Vineetha G.
