From 51e99be00ce2713cbb841cedc997cafa6e26c7f4 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 9 Dec 2009 17:43:19 +0900 Subject: m68k: rename global variable vmalloc_end to m68k_vmalloc_end On SUN3, m68k defines macro VMALLOC_END as unsigned long variable vmalloc_end which is adjusted from mmu_emu_init(). This becomes problematic if a local variables vmalloc_end is defined in some function (not very unlikely) and VMALLOC_END is used in the function - the function thinks its referencing the global VMALLOC_END value but would be referencing its own local vmalloc_end variable. Rename the global variable to m68k_vmlloc_end which is much less likely to be used as local variable name.
