2020-05-19ACPI: APEI: Kick the memory_failure() queue for synchronous errorsJames Morse
memory_failure() offlines or repairs pages of memory that have been discovered to be corrupt. These may be detected by an external component, (e.g. the memory controller), and notified via an IRQ. In this case the work is queued as not all of memory_failure()s work can happen in IRQ context. If the error was detected as a result of user-space accessing a corrupt memory location the CPU may take an abort instead. On arm64 this is a 'synchronous external abort', and on a firmware first system it is replayed using NOTIFY_SEA. This notification has NMI like properties, (it can interrupt IRQ-masked code), so the memory_failure() work is queued. If we return to user-space before the queued memory_failure() work is processed, we will take the fault again. This loop may cause platform firmware to exceed some threshold and reboot when Linux could have recovered from this error. For NMIlike notifications keep track of whether memory_failure() work was queued, and make task_work pending to flush out the queue. To save memory allocations, the task_work is allocated as part of the ghes_estatus_node, and free()ing it back to the pool is deferred.

2020-04-04x86: ACPI: fix CPU hotplug deadlockQian Cai
Similar to commit 0266d81e9bf5 ("acpi/processor: Prevent cpu hotplug deadlock") except this is for acpi_processor_ffh_cstate_probe(): "The problem is that the work is scheduled on the current CPU from the hotplug thread associated with that CPU. It's not required to invoke these functions via the workqueue because the hotplug thread runs on the target CPU already. Check whether current is a per cpu thread pinned on the target CPU and invoke the function directly to avoid the workqueue."

2020-03-25ACPICA: Allow acpi_any_gpe_status_set() to skip one GPERafael J. Wysocki
The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring. For this reason, redefine acpi_any_gpe_status_set() to take the number of a GPE to skip as an argument.

Commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") overlooked the fact that fixed events can wake up the system too and broke RTC wakeup from suspend-to-idle as a result. Fix this issue by checking the fixed events in acpi_s2idle_wake() in addition to checking wakeup GPEs and break out of the suspend-to-idle loop if the status bits of any enabled fixed events are set then.

2019-10-28ACPICA: make acpi_load_table() return table indexNikolaus Voss
ACPICA commit d1716a829d19be23277d9157c575a03b9abb7457 For unloading an ACPI table, it is necessary to provide the index of the table. The method intended for dynamically loading or hotplug addition of tables, acpi_load_table(), should provide this information via an optional pointer to the loaded table index. This patch fixes the table unload function of acpi_configfs.

2019-10-21cpufreq: Use per-policy frequency QoSRafael J. Wysocki
Replace the CPU device PM QoS used for the management of min and max frequency constraints in cpufreq (and its users) with per-policy frequency QoS to avoid problems with cpufreq policies covering more then one CPU. Namely, a cpufreq driver is registered with the subsys interface which calls cpufreq_add_dev() for each CPU, starting from CPU0, so currently the PM QoS notifiers are added to the first CPU in the policy (i.e. CPU0 in the majority of cases). In turn, when the cpufreq driver is unregistered, the subsys interface doing that calls cpufreq_remove_dev() for each CPU, starting from CPU0, and the PM QoS notifiers are only removed when cpufreq_remove_dev() is called for the last CPU in the policy, say CPUx, which as a rule is not CPU0 if the policy covers more than one CPU. Then, the PM QoS notifiers cannot be removed, because CPUx does not have them, and they are still there in the device PM QoS notifiers list of CPU0, which prevents new PM QoS notifiers from being registered for CPU0 on the next attempt to register the cpufreq driver. The same issue occurs when the first CPU in the policy goes offline before unregistering the driver. After this change it does not matter which CPU is the policy CPU at the driver registration time and whether or not it is online all the time, because the frequency QoS is per policy and not per CPU.
