From: Bob Moore <robert.moore@xxxxxxxxx> ACPICA commit e1342c9f2dde37a67e916099658b65984ef8a434 Implicit result conversion was incorrectly disabled for the following functions: FromBCD ToBCD ToDecimalString ToHexString ToInteger ToBuffer Subject rephrased by Lv Zheng due to SMTP 550: The capital Triple-X in subject is a way too often associated with junk email.
