      ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep states · a4e90bed
      Rafael J. Wysocki authored
      If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
      the optional sleep control and sleep status registers for making
      the system enter sleep states (including S5), so it is not possible
      to use system sleep states or power it off using ACPI if the HW
      Reduced ACPI mode bit is set and those registers are not available.
      
      For this reason, add a new function, acpi_sleep_state_supported(),
      checking if the HW Reduced ACPI mode bit is set and whether or not
      system sleep states are usable in that case in addition to checking
      the return value of acpi_get_sleep_type_data() and make the ACPI
      sleep setup routines use that function to check the availability of
      system sleep states.
      
      Among other things, this prevents the kernel from attempting to
      use ACPI for powering off HW Reduced ACPI systems without the sleep
      control and sleep status registers, because ACPI power off doesn't
      have a chance to work on them.  That allows alternative power off
      mechanisms that may actually work to be used on those systems.  The
      affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
      Desktop SDP and Ivy Bridge EP Demo depot.
