Subject: [PATCH 5/6] powerpc/powernv: Add opal details to dump stack arch description
Date: Tue,  5 May 2015 21:12:16 +1000	[thread overview]
Message-ID: <1430824337-15339-5-git-send-email-mpe@ellerman.id.au> (raw)
In-Reply-To: <1430824337-15339-1-git-send-email-mpe@ellerman.id.au>

Once we have unflattened the device tree we can easily grab these opal
version details and add them to dump stack arch description, which is
printed in case of an oops.
