2020-11-22mm: fix phys_to_target_node() and memory_add_physaddr_to_nid() exportsDan Williams1-1/+0
The core-mm has a default __weak implementation of phys_to_target_node() to mirror the weak definition of memory_add_physaddr_to_nid(). That symbol is exported for modules. However, while the export in mm/memory_hotplug.c exported the symbol in the configuration cases of: CONFIG_NUMA_KEEP_MEMINFO=y CONFIG_MEMORY_HOTPLUG=y ...and: CONFIG_NUMA_KEEP_MEMINFO=n CONFIG_MEMORY_HOTPLUG=y ...it failed to export the symbol in the case of: CONFIG_NUMA_KEEP_MEMINFO=y CONFIG_MEMORY_HOTPLUG=n Not only is that broken, but Christoph points out that the kernel should not be exporting any __weak symbol, which means that memory_add_physaddr_to_nid() example that phys_to_target_node() copied is broken too. Rework the definition of phys_to_target_node() and memory_add_physaddr_to_nid() to not require weak symbols. Move to the common arch override design-pattern of an asm header defining a symbol to replace the default implementation. The only common header that all memory_add_physaddr_to_nid() producing architectures implement is asm/sparsemem.h. In fact, powerpc already defines its memory_add_physaddr_to_nid() helper in sparsemem.h. Double-down on that observation and define phys_to_target_node() where necessary in asm/sparsemem.h. An alternate consideration that was discarded was to put this override in asm/numa.h, but that entangles with the definition of MAX_NUMNODES relative to the inclusion of linux/nodemask.h, and requires powerpc to grow a new header. The dependency on NUMA_KEEP_MEMINFO for DEV_DAX_HMEM_DEVICES is invalid now that the symbol is properly exported / stubbed in all combinations of CONFIG_NUMA_KEEP_MEMINFO and CONFIG_MEMORY_HOTPLUG.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs. The simplest fix, explained in detail in Lukas' commit message, is to move to a devm_ function for allocation of the controller and hence driver data in order to push the free of that after anything tries to reference the driver data in the remove path. This results in a relatively large diff due to the addition of a new function but isn't particularly complex. There's also a fix from Sven van Asbroeck which fixes yet more fallout from the conflicts between the various different places one can configure the polarity of GPIOs in modern systems.

2020-11-19HID: logitech-dj: Fix Dinovo Mini when paired with a MX5x00 receiverHans de Goede2-0/+26
Some users are pairing the Dinovo keyboards with the MX5000 or MX5500 receivers, instead of with the Dinovo receivers. The receivers are mostly the same (and the air protocol obviously is compatible) but currently the Dinovo receivers are handled by hid-lg.c while the MX5x00 receivers are handled by logitech-dj.c. When using a Dinovo keyboard, with its builtin touchpad, through logitech-dj.c then the touchpad stops working because when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired mouse, we have nowhere to send mouse-events to, so we drop them. Extend the existing fix for the Dinovo Edge for this to also cover the Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the Media key on the Dinovo Mini, so that that keeps working too.

2020-11-19drm/i915: Handle max_bpc==16Ville Syrjälä1-1/+2
EDID can declare the maximum supported bpc up to 16, and apparently there are displays that do so. Currently we assume 12 bpc is tha max. Fix the assumption and toss in a MISSING_CASE() for any other value we don't expect to see. This fixes modesets with a display with EDID max bpc > 12. Previously any modeset would just silently fail on platforms that didn't otherwise limit this via the max_bpc property. In particular we don't add the max_bpc property to HDMI ports on gmch platforms, and thus we would see the raw max_bpc coming from the EDID. I suppose we could already adjust this to also allow 16bpc, but seeing as no current platform supports that there is little point.

2020-11-18drm/amd/display: Always get CRTC updated constant values inside commit tailRodrigo Siqueira1-1/+2
We recently improved our display atomic commit and tail sequence to avoid some issues related to concurrency. One of the major changes consisted of moving the interrupt disable and the stream release from our atomic commit to our atomic tail (commit 6d90a208cfff ("drm/amd/display: Move disable interrupt into commit tail")) . However, the new code introduced inside our commit tail function was inserted right after the function drm_atomic_helper_update_legacy_modeset_state(), which has routines for updating internal data structs related to timestamps. As a result, in certain conditions, the display module can reach a situation where we update our constants and, after that, clean it. This situation generates the following warning: amdgpu 0000:03:00.0: drm_WARN_ON_ONCE(drm_drv_uses_atomic_modeset(dev)) WARNING: CPU: 6 PID: 1269 at drivers/gpu/drm/drm_vblank.c:722 drm_crtc_vblank_helper_get_vblank_timestamp_internal+0x32b/0x340 [drm] ...

Basically, this commit uses this new helper and place it right after our release module to avoid a situation where our CRTC struct gets wrong values.

The driver sends Ethernet Management Datagram (EMAD) packets to the device for configuration purposes and waits for up to 200ms for a reply. A request is retried up to 5 times. When the system is under heavy load, replies are not always processed in time and EMAD transactions fail. Make the process more robust to such delays by using exponential backoff. First wait for up to 200ms, then retransmit and wait for up to 400ms and so on.

2020-11-18regulator: ti-abb: Fix array out of bound read access on the first transitionNishanth Menon1-1/+11
At the start of driver initialization, we do not know what bias setting the bootloader has configured the system for and we only know for certain the very first time we do a transition. However, since the initial value of the comparison index is -EINVAL, this negative value results in an array out of bound access on the very first transition. Since we don't know what the setting is, we just set the bias configuration as there is nothing to compare against. This prevents the array out of bound access. NOTE: Even though we could use a more relaxed check of "< 0" the only valid values(ignoring cosmic ray induced bitflips) are -EINVAL, 0+.

2020-11-18can: flexcan: flexcan_chip_start(): fix erroneous ↵Marc Kleine-Budde1-9/+9
flexcan_transceiver_enable() during bus-off recovery If the CAN controller goes into bus off, the do_set_mode() callback with CAN_MODE_START can be used to recover the controller, which then calls flexcan_chip_start(). If configured, this is done automatically by the framework or manually by the user. In flexcan_chip_start() there is an explicit call to flexcan_transceiver_enable(), which does a regulator_enable() on the transceiver regulator. This results in a net usage counter increase, as there is no corresponding flexcan_transceiver_disable() in the bus off code path. This further leads to the transceiver stuck enabled, even if the CAN interface is shut down. To fix this problem the flexcan_transceiver_enable()/flexcan_transceiver_disable() are moved out of flexcan_chip_start()/flexcan_chip_stop() into flexcan_open()/flexcan_close().

"intel_iommu=off" command line is used to disable iommu but iommu is force enabled in a tboot system for security reason. However for better performance on high speed network device, a new option "intel_iommu=tboot_noforce" is introduced to disable the force on. By default kernel should panic if iommu init fail in tboot for security reason, but it's unnecessory if we use "intel_iommu=tboot_noforce,off". Fix the code setting force_on and move intel_iommu_tboot_noforce from tboot code to intel iommu code.

2020-11-18dmaengine: fix error codes in channel_register()Dan Carpenter1-8/+9
The error codes were not set on some of these error paths. Also the error handling was more confusing than it needed to be so I cleaned it up and shuffled it around a bit.
