ACPI: ACPICA 20060526
Restructured, flattened, and simplified the internal interfaces for namespace object evaluation - resulting in smaller code, less CPU stack use, and fewer interfaces. (With assistance from Mikhail Kouzmich) Fixed a problem with the CopyObject operator where the first parameter was not typed correctly for the parser, interpreter, compiler, and disassembler. Caused various errors and unexpected behavior. Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits produced incorrect results with some C compilers. Since the behavior of C compilers when the shift value is larger than the datatype width is apparently not well defined, the interpreter now detects this condition and simply returns zero as expected in all such cases. (BZ 395) Fixed problem reports (Valery Podrezov) integrated: - Update String-to-Integer conversion to match ACPI 3.0A spec http://bugzilla.kernel.org/show_bug.cgi?id=5329 Allow interpreter to handle nested method declarations http://bugzilla.kernel.org/show_bug.cgi?id=5361 Fixed problem reports (Fiodor Suietov) integrated: - acpi_terminate() doesn't free debug memory allocation list objects (BZ 355) - After Core Subsystem shutdown, acpi_subsystem_status() returns AE_OK (BZ 356) - acpi_os_unmap_memory() for RSDP can be invoked inconsistently (BZ 357) - Resource Manager should return AE_TYPE for non-device objects (BZ 358) - Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359) - Use acpi_os_free() instead of ACPI_FREE in acpi_rs_set_srs_method_data (BZ 360) - Incomplete cleanup branch in acpi_ps_parse_aml (BZ 361) - Incomplete cleanup branch in acpi_ds_delete_walk_state (BZ 362) - acpi_get_table_header returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365) - Status of the Global Initialization Handler call not used (BZ 366) - Incorrect object parameter to Global Initialization Handler (BZ 367) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
