139 * Entry points to ACPI from above are global functions defined in this
140 * file, sysctls, and I/O on the control device. Entry points from below
141 * are interrupts (the SCI), notifies, task queue threads, and the thermal
142 * zone polling thread.
143 *
144 * ACPI tables and global shared data are protected by a global lock
145 * (acpi_lock).
146 *
147 * Each ACPI device can have its own driver-specific mutex for protecting
148 * shared access to local data. The ACPI_LOCK macros handle mutexes.
149 *
150 * Drivers that need to serialize access to functions (e.g., to route
151 * interrupts, get/set control paths, etc.) should use the sx lock macros
152 * (ACPI_SERIAL).
153 *
154 * ACPI-CA handles its own locking and should not be called with locks held.
