+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+This is needed for the Maia SDR kernel module, which calls

+Subject: [PATCH] arch: arm: export Zynq cache invalidation functions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is needed for the Maia SDR kernel module, which calls
+these functions directly rather than going through the DMA API.
