From 7ae5a761d2ffc4cf7d3248e09f4d3da234434f30 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 6 Feb 2007 17:39:31 +0000 Subject: [ARM] Convert DMA cache handling to take const void * args The DMA cache handling functions take virtual addresses, but in the form of unsigned long arguments. This leads to a little confusion about what exactly they take. So, convert them to take const void * instead.
