From 81ac3ad9061dd9cd490ee92f0c5316a14d77ce18 Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Tue, 22 Sep 2009 16:45:49 -0700 Subject: kcore: register module area in generic way Some archs define MODULED_VADDR/MODULES_END which is not in VMALLOC area. This is handled only in x86-64. This patch make it more generic. And we can use vread/vwrite to access the area. Fix it.
