From 8fc63658681f32e6e29f6d1138de933d7272e0ec Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 30 Apr 2008 13:38:44 +0200 Subject: [PATCH] [S390] vmemmap: use clear_table to initialise page tables. Always use clear_table to initialise page tables. The overlapping memcpy is just a leftover of a previous version that wasn't fully converted to clear_table.
