Subject: [PATCH v2 2/2] powerpc/pseries: Remove call to memblock_add()
Date: Wed, 29 Jun 2016 12:20:30 -0500 [thread overview]
Message-ID: <5774035E.3080403@linux.vnet.ibm.com> (raw)
In-Reply-To: <5774027B.6070708@linux.vnet.ibm.com>
The call to memblock_add is not needed, this is already done by
memory_add(). This patch removes this call which shrinks
dlpar_add_lmb_memory() enough that it can be merged into dlpar_add_lmb().
