From 0b94a1eeeeb3542d046b928ca01fcd4bf0ea7587 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 17 Sep 2007 16:05:00 +1000 Subject: [POWERPC] Store the base address in dcr_host_t In its current form, dcr_map() doesn't remember the base address you passed it, which means you need to store it somewhere else. Rather than adding the base to another struct it seems simpler to store it in the dcr_host_t.
