Subject: [RFC PATCH v1 2/3] powerpc: Mark all .S files invalid for objtool
A lot of work is required in .S files in order to get them ready
for objtool checks.
For the time being, exclude them from the checks.
This is done with the script below:
#!/bin/sh
DIRS=`find arch/powerpc -name "*.S" -exec dirname {} \; | sort | uniq`
for d in $DIRS
do
pushd $d
echo >> Makefile
for f in *.S
do
echo "OBJECT_FILES_NON_STANDARD_$f := y" | sed s/"\.S"/".o"/g
done >> Makefile
popd
done
