Subject: [PATCH v3 5/7] powerpc: Add ppc_md.name to dump stack arch description

From: Michael Ellerman <[email-masked]>
Date: Thu, 7 Feb 2019 23:46:33 +1100

As soon as we know the name of the machine description we're using, add
it to the dump stack arch description, which is printed in case of an
oops.

eg: Hardware name: ... machine:pSeries
