From 843b8ed2ec598aae5e3516b21957ede62a070e36 Mon Sep 17 00:00:00 2001 From: Attilio Rao Date: Tue, 21 Aug 2012 21:22:39 +0100 Subject: [PATCH] x86: Move paging_init() call to x86_init.paging.pagetable_init() Move the paging_init() call to the platform specific pagetable_init() function, so we can get rid of the extra pagetable_setup_done() function pointer.
