From 0eefed84fe9e1eb90f4b089ead95904306b23233 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 31 Oct 2010 21:23:55 +0100 Subject: [PATCH] m68k/sun3: Kill pte_unmap() warnings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 31c911329e048b715a1dfeaaf617be9430fd7f4e ("mm: check the argument of kunmap on architectures without highmem"), we get lots of warnings like arch/m68k/kernel/sys_m68k.c:508: warning: passing argument 1 of ‘kunmap’ from incompatible pointer type As m68k doesn't support highmem anyway, open code the calls to kmap() and kunmap() (the latter is a no-op) to kill the warnings, like is done on most other architectures without CONFIG_HIGHPTE.
