2023-02-14alpha: fix R_ALPHA_LITERAL reloc for large modulesEdward Humes
Previously, R_ALPHA_LITERAL relocations would overflow for large kernel modules. This was because the Alpha's apply_relocate_add was relying on the kernel's module loader to have sorted the GOT towards the very end of the module as it was mapped into memory in order to correctly assign the global pointer. While this behavior would mostly work fine for small kernel modules, this approach would overflow on kernel modules with large GOT's since the global pointer would be very far away from the GOT, and thus, certain entries would be out of range. This patch fixes this by instead using the Tru64 behavior of assigning the global pointer to be 32KB away from the start of the GOT. The change made in this patch won't work for multi-GOT kernel modules as it makes the assumption the module only has one GOT located at the beginning of .got, although for the vast majority kernel modules, this should be fine. Of the kernel modules that would previously result in a relocation error, none of them, even modules like nouveau, have even come close to filling up a single GOT, and they've all worked fine under this patch.

Pull kvm fixes from Paolo Bonzini: "Certain AMD processors are vulnerable to a cross-thread return address predictions bug. When running in SMT mode and one of the sibling threads transitions out of C0 state, the other thread gets access to twice as many entries in the RSB, but unfortunately the predictions of the now-halted logical processor are not purged. Therefore, the executing processor could speculatively execute from locations that the now-halted processor had trained the RSB on. The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB when context switching to the idle thread. However, KVM allows a VMM to prevent exiting guest mode when transitioning out of C0 using the KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change this behavior. To mitigate the cross-thread return address predictions bug, a VMM must not be allowed to override the default behavior to intercept C0 transitions. These patches introduce a KVM module parameter that, if set, will prevent the user from disabling the HLT, MWAIT and CSTATE exits" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: Documentation/hw-vuln: Add documentation for Cross-Thread Return Predictions KVM: x86: Mitigate the cross-thread return address predictions bug x86/speculation: Identify processors vulnerable to SMT RSB predictions

During removal of the glink edge interrupts are disabled and no more incoming messages are being serviced. In addition to the remote endpoint being defunct that means that any outstanding requests for intents will not be serviced, and qcom_glink_request_intent() will blindly wait for up to 10 seconds. Mark the intent request as not granted and complete the intent request completion to fail the waiting client immediately. Once the current intent request is failed, any potential clients waiting for the intent request mutex will not enter the same wait, as the qcom_glink_tx() call will fail fast.

2023-02-14ALSA: hda: cs35l41: Ensure firmware/tuning pairs are always loadedStefan Binding
To ensure firmware for cs35l41 is correctly running, it is necessary that a corresponding tuning file is also loaded. Without both, the firmware may not be performing correctly Ensure that if we load the firmware, we have also loaded the correct tuning file. Otherwise, fall back to default firmware and tuning. If default tuning is also missing, then disable DSP firmware.
