#     
#     Pull ACPI fixes from Rafael Wysocki:
#      "These address a device ID bounds check error in the device enumeration
#       code and fix a mistake in the documentation.
#     
#       Specifics:
#     
#        - Harden the ACPI device enumeration code against device ID length
#          overflows to address a Linux VM cash on Hyper-V (Dexuan Cui).
#     
#        - Fix a mistake in the documentation of error type values for PCIe
#          errors (Qiuxu Zhuo)"
