   6 This one is part of a patch series:
   7 acpi_thinkpad_introduce_acpi_root_table_boot_param.patch
   8 acpi_thinkpad_introduce_acpica_rsdt_global_variable.patch
   9 acpi_thinkpad_remove_R40e_c-state_blacklist.patch

  12 The FADT pointed to through XSDT is wrong on this (and similar)
  13 machines.
  14 The HW addresses to switch C-states are coming from the FADT.
  15 When using the FADT pointed to in the RSDT the info is correct.
  16 Previous patches blacklist this machine to use the right FADT and
  17 C-states finally work fine.
