acpi_is_global_locked() functions. AcpiGlobalLock() API should be used to acquire lock between BIOS and OS. This API cannot be used to lock between threads of the OS side, because this function immediately returns if the lock is already acquired by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c - make sure that acpiec driver uses above functions. - use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(), in acpi_eval_string()/acpi_eval_struct(). Twice AcpiEvaluateObject() calls may cause twice side effects to ACPI machine / hardware and this may be wrong in some cases.
