  ACPICA: Limit maximum time for Sleep() operator
  ACPICA: Fix namestring associated with AE_NO_HANDLER exception
  ACPI / ACPICA: Fix sysfs GPE interface
  ACPI / ACPICA: Fix GPE initialization
  ACPI / ACPICA: Avoid writing full enable masks to GPE registers
  ACPI / ACPICA: Fix low-level GPE manipulation code
  ACPI / ACPICA: Use helper function for computing GPE masks
  ACPI / ACPICA: Do not attempt to disable GPE when installing handler
  ACPI: Disable Vista compatibility for Sony VGN-NS50B_L
  ACPI: fan: fix unbalanced code block
  ACPI: Store NVS state even when entering suspend to RAM
  suspend: Move NVS save/restore code to generic suspend functionality
  ACPI: Do not try to set up acpi processor stuff on cores exceeding maxcpus=
  ACPI: acpi_pad: Don't needlessly mark LAPIC unstable
