Subject: [PATCH v2 4/6] arm64: mm: make use of new memblocks_present() helper
Date: Mon, 15 Oct 2018 11:57:00 -0600 [thread overview]
Message-ID: <20181015175702.9036-5-logang@deltatee.com> (raw)
Message-ID: <20181015175700.86py78yg8ug6jDnyWkQR0VKeCXF1M8GmnXLhV6yHvxk@z> (raw)
In-Reply-To: <20181015175702.9036-1-logang@deltatee.com>
Cleanup the arm64_memory_present() function seeing it's very
similar to other arches.
memblocks_present() is a direct replacement of arm64_memory_present()
