[PATCH 4.11 32/88] sed regex in Makefile.build requires line break between exported symbols
From: Greg Kroah-Hartman
Date: Wed Jul 19 2017 - 06:10:21 EST
4.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nagarathnam Muthusamy <nagarathnam.muthusamy@xxxxxxxxxx>
[ Upstream commit d16c0649feb4fe4e814f44803df5a617769c3233 ]
The following regex in Makefile.build matches only one ___EXPORT_SYMBOL per line.
sed
's/.*___EXPORT_SYMBOL[[:space:]]*\([a-zA-Z0-9_]*\)[[:space:]]*,.*/EXPORT_SYMBOL(\1);/'
ATOMIC_OPS macro in atomic_64.S expands multiple symbols in same line hence
version generation is done only for the last matched symbol. This patch adds
new line between the symbol expansions.
