Subject: [PATCH 1/2] powerpc/eeh: Create PHB PEs after EEH is initialized
Date: Thu, 07 Sep 2017 16:35:40 +1000	[thread overview]
Message-ID: <1504766140.12628.14.camel@kernel.crashing.org> (raw)

Otherwise we end up not yet having computed the right
diag data size on powernv where EEH initialization
is delayed, thus causing memory corruption later on
when calling OPAL.
