2020-08-28selftests/bpf: Fix massive output from test_mapsJesper Dangaard Brouer
When stdout output from the selftests tool 'test_maps' gets redirected into e.g file or pipe, then the output lines increase a lot (from 21 to 33949 lines). This is caused by the printf that happens before the fork() call, and there are user-space buffered printf data that seems to be duplicated into the forked process. To fix this fflush() stdout before the fork loop in __run_parallel().

2020-08-28arm64: use a common .arch preamble for inline assemblySami Tolvanen
Commit 7c78f67e9bd9 ("arm64: enable tlbi range instructions") breaks LLVM's integrated assembler, because -Wa,-march is only passed to external assemblers and therefore, the new instructions are not enabled when IAS is used. This change adds a common architecture version preamble, which can be used in inline assembly blocks that contain instructions that require a newer architecture version, and uses it to fix __TLBI_0 and __TLBI_1 with ARM64_TLB_RANGE.

After the recent conversion of the media build infrastructure to select V4L2 components instead of depending on their presence, which took place in: 32a363d0b0b14 ("media: Kconfig files: use select for V4L2 subdevs and MC") imx214 stands out as being the (only?) media I2C driver that still depends on a V4L2 core symbol instead of selecting it.

2020-08-28mfd: mfd-core: Ensure disabled devices are ignored without errorLee Jones
Commit e49aa9a9bd22 ("mfd: core: Make a best effort attempt to match devices with the correct of_nodes") changed the semantics for disabled devices in mfd_add_device(). Instead of silently ignoring a disabled child device, an error was returned. On receipt of the error mfd_add_devices() the precedes to remove *all* child devices and returns an all-failed error to the caller, which will inevitably fail the parent device as well. This patch reverts back to the old semantics and ignores child devices which are disabled in Device Tree.

commit b5a84ecf025a ("mmc: tegra: Add Tegra210 support") Tegra210 and later has a separate sdmmc_legacy_tm (TMCLK) used by Tegra SDMMC hawdware for data timeout to achive better timeout than using SDCLK and using TMCLK is recommended. USE_TMCLK_FOR_DATA_TIMEOUT bit in Tegra SDMMC register SDHCI_TEGRA_VENDOR_SYS_SW_CTRL can be used to choose either TMCLK or SDCLK for data timeout. Default USE_TMCLK_FOR_DATA_TIMEOUT bit is set to 1 and TMCLK is used for data timeout by Tegra SDMMC hardware and having TMCLK not enabled is not recommended. So, this patch adds quirk NVQUIRK_HAS_TMCLK for SoC having separate timeout clock and keeps TMCLK enabled all the time.

2020-08-27net: ethernet: ti: cpsw_new: fix error handling in cpsw_ndo_vlan_rx_kill_vid()Murali Karicheri
This patch fixes a bunch of issues in cpsw_ndo_vlan_rx_kill_vid() - pm_runtime_get_sync() returns non zero value. This results in non zero value return to caller which will be interpreted as error. So overwrite ret with zero. - If VID matches with port VLAN VID, then set error code. - Currently when VLAN interface is deleted, all of the VLAN mc addresses are removed from ALE table, however the return values from ale function calls are not checked. These functions can return error code -ENOENT. But that shouldn't happen in a normal case. So add error print to catch the situations so that these can be investigated and addressed. return zero in these cases as these are not real error case, but only serve to catch ALE table update related issues and help address the same in the driver.

If sun8i_r40_tcon_tv_set_mux() succeed, sun8i_r40_tcon_tv_set_mux() doesn't have a corresponding put_device(). Thus add put_device() to fix the exception handling for this function implementation.

2020-08-27EDAC/ghes: Fix NULL pointer dereference in ghes_edac_register()Shiju Jose
After b9cae27728d1 ("EDAC/ghes: Scan the system once on driver init") and with CONFIG_DEBUG_TEST_DRIVER_REMOVE enabled, ghes_hw.dimms becomes a NULL pointer after the second ->probe() (aka ghes_edac_register()) which the config option causes to be called. This happens because the static variable which holds down whether the system has been scanned already, doesn't get reset in ghes_edac_unregister(). Then, on the second probe, ghes_scan_system() doesn't get to enumerate the DIMMs, leading to ghes_hw.dimms remaining NULL. Clear the variable and rename it to something more descriptive so that a second probe succeeds.

2020-08-27drm/sun4i: lvds: Invert the LVDS polarityMaxime Ripard
The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels.

2020-08-27drm/amdgpu: Fix bug in reporting voltage for CIKSandeep Raghuraman
On my R9 390, the voltage was reported as a constant 1000 mV. This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor() function, where some magic constants were used in a condition, to determine whether the voltage should be read from PLANE2_VID or PLANE1_VID. The VDDC mask was incorrectly used, instead of the VDDGFX mask. This patch changes the code to use the correct defined constants (and apply the correct bitshift), thus resulting in correct voltage reporting.

Starting in Linux 5.8, the graphics and memory clock frequency were not being reported for CIK cards. This is a regression, since they were reported correctly in Linux 5.7. After investigation, I discovered that the smum_send_msg_to_smc() function, attempts to call the corresponding get_argument() function of ci_smu_funcs. However, the get_argument() function is not defined in ci_smu_funcs. This patch fixes the bug by specifying the correct get_argument() function.

2020-08-27crypto: af_alg - Work around empty control messages without MSG_MOREHerbert Xu
The iwd daemon uses libell which sets up the skcipher operation with two separate control messages. As the first control message is sent without MSG_MORE, it is interpreted as an empty request. While libell should be fixed to use MSG_MORE where appropriate, this patch works around the bug in the kernel so that existing binaries continue to work. We will print a warning however. A separate issue is that the new kernel code no longer allows the control message to be sent twice within the same request. This restriction is obviously incompatible with what iwd was doing (first setting an IV and then sending the real control message). This patch changes the kernel so that this is explicitly allowed.
