2020-10-05serial: fsl_lpuart: add sysrq support when using dmaAngelo Dureghello
Add handling of magic sysrq keys when using dma/edma. Tested by sending BREAK followed by a sysrq command inside a 5 secs time window, by: echo 1 > /proc/sys/kernel/sysrq BREAK + h, t, e, b, c Tested also sending a command after 5 secs after BREAK, that's properly ignored.

2020-10-05ACPI: button: fix handling lid state changes when input device closeddmitry.torokhov@gmail.com
The original intent of 84d3f6b76447 was to delay evaluating lid state until all drivers have been loaded, with input device being opened from userspace serving as a signal for this condition. Let's ensure that state updates happen even if userspace closed (or in the future inhibited) input device. Note that if we go through suspend/resume cycle we assume the system has been fully initialized even if LID input device has not been opened yet. This has a side-effect of fixing access to input->users outside of input->mutex protections by the way of eliminating said accesses and using driver private flag.

The fops field in the w1_family struct is never modified. Make it const to indicate that. Constifying the pointer makes it possible for drivers to declare static w1_family_ops structs const, which in turn will allow the compiler to put it in read-only memory.

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.

The jz4780_dma_tx_status() function would check if a channel's cookie state was set to 'completed', and if not, it would enter the critical section. However, in that time frame, the jz4780_dma_chan_irq() function was able to set the cookie to 'completed', and clear the jzchan->vchan pointer, which was deferenced in the critical section of the first function. Fix this race by checking the channel's cookie state after entering the critical function and not before.

2020-10-04x86/xen: disable Firmware First mode for correctable memory errorsJuergen Gross
When running as Xen dom0 the kernel isn't responsible for selecting the error handling mode, this should be handled by the hypervisor. So disable setting FF mode when running as Xen pv guest. Not doing so might result in boot splats like: [ 7.509696] HEST: Enabling Firmware First mode for corrected errors. [ 7.510382] mce: [Firmware Bug]: Ignoring request to disable invalid MCA bank 2.

[ 7.510386] mce: [Firmware Bug]: Ignoring request to disable invalid MCA bank 7. [ 7.510386] mce: [Firmware Bug]: Ignoring request to disable invalid MCA bank 8.

The VCPUOP_register_runstate_memory_area hypercall takes a virtual address of a buffer as a parameter. The semantics of the hypercall are such that the virtual address should always be valid. When KPTI is enabled and we are running userspace code, the virtual address is not valid, thus, Linux is violating the semantics of VCPUOP_register_runstate_memory_area.
