Merge branch 'acpi-pfrut'
Merge support for the Platform Firmware Runtime Update and Telemetry
interface based on ACPI.
The interface provided here allows updating certain pieces of the
platform firmware without restarting the system and collecting
platform firmware telemetry data.
This also includes a utility for accesing the new interface from user
space.
* acpi-pfrut:
ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl()
ACPI: pfr_update: Fix return value check in pfru_write()
ACPI: tools: Introduce utility for firmware updates/telemetry
ACPI: Introduce Platform Firmware Runtime Telemetry driver
ACPI: Introduce Platform Firmware Runtime Update device driver
efi: Introduce EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and corresponding structures
