From 31fcb99d9958bdf04e84224e202f69e6cdac893b Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Thu, 30 Jun 2011 22:52:13 +0000 Subject: [PATCH] net: sh_eth: remove __flush_purge_region It is a function of SuperH architecture. There is no good to use the function on a driver generally. So, the driver uses dma_map_single() instead of __flush_purge_region. Signed-off-by: Yoshihiro Shimoda Signed-off-by: David S.
