From 6a570b28b5948e7bf54ea42ec3161bded0a1c460 Mon Sep 17 00:00:00 2001 From: "Hyok S. Choi" Date: Tue, 26 Sep 2006 17:37:07 +0900 Subject: [PATCH] [ARM] nommu: allows to support module in nommu A simple patch to support module in nommu mode. The vmalloc is used instead of __vmalloc_area which depends on CONFIG_MMU. Signed-off-by: Hyok S.
