From 1598e38c0770b08c4d6371b670f9ee61a42ec68b Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 12 Dec 2017 09:08:35 +0100 Subject: [PATCH] serial: forbid 8250 on s390 Using "make kvmconfig" results in a potentially unusable linux image on s390. The reason is that both the (default on s390) sclp consoles as well as the 8250 console register a ttyS as console. Since there will be no 8250 on s390 let's fence 8250. This will ensure that there is always a working sclp console.
