From mboxrd@z Thu Jan 1 00:00:00 1970 From: logang@deltatee.com (Logan Gunthorpe) Date: Mon, 15 Oct 2018 11:56:59 -0600 Subject: [PATCH v2 3/6] ARM: mm: make use of new memblocks_present() helper In-Reply-To: <20181015175702.9036-1-logang@deltatee.com> References: <20181015175702.9036-1-logang@deltatee.com> Message-ID: <20181015175702.9036-4-logang@deltatee.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Cleanup the arm_memory_present() function seeing it's very similar to other arches. The new memblocks_present() helper checks for node ids which the arm version did not. However, this is equivalent seeing HAVE_MEMBLOCK_NODE_MAP should be false in this arch and therefore memblock_get_region_node() should return 0.
