Subject: sata_nv: handle SError status indication
From: Robert Hancock <[EMAIL PROTECTED]>
ADMA-capable controllers provide a bit in the status register that appears
to indicate that the controller detected an SError condition. Update
sata_nv to detect this and trigger error handling in order to handle the
fault.
