Subject: [RFC PATCH 16/29] memblock: replace __alloc_bootmem_node with appropriate memblock_ API
Date:   Wed,  5 Sep 2018 18:59:31 +0300
In-Reply-To: <1536163184-26356-1-git-send-email-rppt@linux.vnet.ibm.com>
References: <1536163184-26356-1-git-send-email-rppt@linux.vnet.ibm.com>
Message-Id: <1536163184-26356-17-git-send-email-rppt@linux.vnet.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use memblock_alloc_try_nid whenever goal (i.e. mininal address is
specified) and memblock_alloc_node otherwise.
