Subject: [PATCH v3 5/7] powerpc: Add ppc_md.name to dump stack arch description
Date: Thu, 7 Feb 2019 23:46:33 +1100 [thread overview]
Message-ID: <20190207124635.3885-5-mpe@ellerman.id.au> (raw)
In-Reply-To: <20190207124635.3885-1-mpe@ellerman.id.au>
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
