ACPI: Handle BIOS that resumes from S3 to suspend routine rather than resume vector
A BIOS has been found that resumes from S3 to the routine that invoked suspend, ignoring the resume vector. This appears to the OS as a failed S3 attempt. This same system suspend/resume's properly with Windows. It is possible to invoke the protected mode register restore routine (which would normally restore the sysenter registers) when the BIOS returns from S3. This has no effect on a correctly running system and repairs the damage from the deviant BIOS.
