From 9e1b9b80721661bd63b3662453767b22cd614fe7 Mon Sep 17 00:00:00 2001 From: Alan Jenkins Date: Sat, 7 Nov 2009 21:03:54 +0000 Subject: module: make MODULE_SYMBOL_PREFIX into a CONFIG option The next commit will require the use of MODULE_SYMBOL_PREFIX in .tmp_exports-asm.S. Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).
