Linux does not use new ACPI 3.0 FADT Fixed Feature Flags

Hmmm,
While ACPI defines these bits that are new with ACPI 3.0, Linux doesn't talk to them yet...

#define ACPI_FADT_PCI_EXPRESS_WAKE  (1<<14)     /* 14: System supports PCIEXP_WAKE (STS/EN) bits (ACPI 3.0) */
#define ACPI_FADT_PLATFORM_CLOCK    (1<<15)     /* 15: OSPM should use platform-provided timer (ACPI 3.0) */
#define ACPI_FADT_S4_RTC_VALID      (1<<16)     /* 16: Contents of RTC_STS valid after S4 wake (ACPI 3.0) */
#define ACPI_FADT_REMOTE_POWER_ON   (1<<17)     /* 17: System is compatible with remote power on (ACPI 3.0) */
#define ACPI_FADT_APIC_CLUSTER      (1<<18)     /* 18: All local APICs must use cluster model (ACPI 3.0) */
#define ACPI_FADT_APIC_PHYSICAL     (1<<19)     /* 19: All local x_aPICs must use physical dest mode (ACPI 3.0) */
