From f456da5e1305672c86e2cbe07483388a75a9bb2e Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 1 Feb 2013 15:21:41 -0500 Subject: [PATCH] tile: fix memcpy_*io functions for allnoconfig On tilepro without CONFIG_PCI, we can't provide inlines of these functions, as we don't have readl/writel. In addition, fix memset_io() signature to take a volatile void *.
