From 1221ed10f2a56ecdd8ff75f436f52aca5ba0f1d3 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 4 Apr 2015 17:25:20 +0100 Subject: [PATCH] ARM: cleanup early_paging_init() calling Eliminate the needless nommu version of this function, and get rid of the proc_info_list structure argument - we no longer need this in order to fix up the page table entries.
