Subject: [PATCH] kexec/s390: Replace clgfi with cghi
Date: Fri, 15 Mar 2013 13:46:32 +0100 [thread overview]
Message-ID: <20130315134632.1177a239@holzheu> (raw)
The clgfi instruction needs at least z9 machine level. To allow kexec-tools
compiled also with z900, this patch replaces clgfi with the older cghi
instruction.
