From 94e58e0ac31284fa26597c0e00a9b1d87a691d02 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 9 May 2018 16:23:49 +0900 Subject: export.h: remove code for prefixing symbols with underscore CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX was selected by BLACKFIN, METAG. They were removed by commit 4ba66a976072 ("arch: remove blackfin port"), commit bb6fb6dfcc17 ("metag: Remove arch/metag/"), respectively. No more architecture enables CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. Clean up the export.h headers. I am keeping VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR() because they are widely used.
