[S390] hypfs: Use subcode 6 if subcode 7 is not available
Michael Holzheu [Wed, 14 Oct 2009 10:43:44 +0000 (12:43 +0200)]
Hypfs never worked on systems that only provide D204 subcode 6.
In these cases we nevertheless used subcode 7. With this fix, we
use subcode 6, if it is available and the system does not provide
subcode 7.
