From 3e37fd3153ac95088a74f5e7c569f7567e9f993a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 17 Nov 2011 18:17:59 -0800 Subject: sparc: Kill custom io_remap_pfn_range(). To handle the large physical addresses, just make a simple wrapper around remap_pfn_range() like MIPS does. Signed-off-by: David S.
