  23           This driver adds support for the ACPI-WMI (Windows Management
  24           Instrumentation) mapper device (PNP0C14) found on some systems.
  25
  26           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
  27           ACPI firmware to userspace - this is done through various vendor
  28           defined methods and data blocks in a PNP0C14 device, which are then
  29           made available for userspace to call.
  30
  31           The implementation of this in Linux currently only exposes this to
  32           other kernel space drivers.
  33
  34           This driver is a required dependency to build the firmware specific
  35           drivers needed on many machines, including Acer and HP laptops.
  36

  38           any ACPI-WMI devices.

1006
1007           IMRs make it possible to control read/write access to an address
1008           by hardware agents inside the SoC. Read and write masks can be
