ACPI: APEI: Kick the memory_failure() queue for synchronous errors

2020-05-19T17:51:11Z

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.

ACPI: utils: Add acpi_evaluate_reg() helper

2020-05-09T09:40:25Z

With a recent fix to the pinctrl-cherryview driver we now have 2 drivers open-coding the parameter building / passing for calling _REG on an ACPI handle. Add a helper for this, so that these 2 drivers can be converted to this helper. Suggested-by: Andy Shevchenko Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
