+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ * the latest version of Windows, which would respond to the latest/newest
+ * _OSI string. Not responding TRUE to the latest version of Windows will
+ * risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ * has the potential to cause problems on existing working machines because
+ * of the possibility that a new and different path through the ASL code
+ * will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ * in recognizing a new string for a significant amount of time risks the
+ * release of another string which only compounds the initial problem.
+ *
