From 9dec17eb577169f78d642c5424e4264186d27115 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 10 Jul 2006 04:44:51 -0700 Subject: [PATCH] FRV: Fix FRV arch compile errors Fix some FRV arch compile errors, including: (*) Marking nr_kernel_pages as __meminitdata so that references to it end up being properly calculated rather than being assumed to be in the small data section (and thus calculated wrt the GP register). Not doing this causes the linker to emit errors as the offset is too big to fit into the load instruction. (*) Move pm_power_off into an unconditionally compiled .c file as it's now unconditionally accessed. (*) Declare frv_change_cmode() in a header file rather than in a .c file, and declare it asmlinkage.
