Subject: [S390] s390/setup: set default preferred console device "ttyS"
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0946100f566d04cc93e86654f3ba588ee94b3f4c;p=deliverable%2Flinux.git

[S390] s390/setup: set default preferred console device "ttyS"

This patch sets the default console device for s390.

The console= kernel parameter can be still used to switch the preferred
console to some other device. In that case, console messages are also
printed on the default console device (ttyS0).
