2022-01-23arm64: dts: exynos: add necessary clock inputs in Exynos7Krzysztof Kozlowski1-6/+27
Exynos7 devicetree bindings require more input clocks for TOP0 and PERIC1 clock controllers, than already provided. Existing DTS was not matching the bindings, so let's update the DTS, even though the error could be in the bindings.

2022-01-23ARM: dts: exynos: add necessary clock controller inputs in Exynos5260Krzysztof Kozlowski2-0/+149
Exynos5260 bindings require to feed clock controllers with certain clock inputs. The IO clocks are expected to be provided by the board. The PHY clocks are usually followed by mux which can choose between the PHY clock and main 24 MHz oscillator, so skip defining them and just use the latter one.

2022-01-23arm64: dts: exynos: use dedicated wake-up pinctrl compatible in ExynosAutov9Krzysztof Kozlowski1-1/+1
Older Samsung Exynos SoC pin controller nodes (Exynos3250, Exynos4, Exynos5, Exynos5433) with external wake-up interrupts, expected to have one interrupt for multiplexing these wake-up interrupts. Also they expected to have exactly one pin controller capable of external wake-up interrupts. It seems however that newer ARMv8 Exynos SoC like Exynos850 and ExynosAutov9 have differences: 1. No multiplexed external wake-up interrupt, only direct, 2. More than one pin controller capable of external wake-up interrupts. Use dedicated ExynosAutov9 compatible for its external wake-up interrupts controller to indicate the differences.

machine check validity bits reflect the state of the machine check. If a guest does not make use of guarded storage, the validity bit might be off. We can not use the host CR bit to decide if the validity bit must be on. So ignore "invalid" guarded storage controls for KVM guests in the host and rely on the machine check being forwarded to the guest. If no other errors happen from a host perspective everything is fine and no process must be killed and the host can continue to run.

2022-01-22KVM: arm64: vgic-v3: Restrict SEIS workaround to known broken systemsMarc Zyngier2-2/+18
Contrary to what df652bcf1136 ("KVM: arm64: vgic-v3: Work around GICv3 locally generated SErrors") was asserting, there is at least one other system out there (Cavium ThunderX2) implementing SEIS, and not in an obviously broken way. So instead of imposing the M1 workaround on an innocent bystander, let's limit it to the two known broken Apple implementations.

2022-01-22mm: remove cleancacheChristoph Hellwig16-16/+0
Patch series "remove Xen tmem leftovers". Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap. This patch (of 13): The cleancache subsystem is unused since the removal of Xen tmem driver in commit 814bbf49dcd0 ("xen: remove tmem driver").
