Provide a new lock type acpi_raw_spinlock which is implemented as raw_spinlock_t on Linux. This type should be used in code which covers small areas of code and disables interrupts only for short time even on a realtime OS. There is a fallback to spinlock_t if an OS does not provide an implementation for acpi_raw_spinlock. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
