From: Riku Voipio <riku.voipio@xxxxxxxxxx>
When building with $srctree != $objtree, perf-tar-* targets fail
to read the MANIFEST file and add the PERF-VERSION-FILE needed
by out-of-tree builds. The build errors and an incorrect tar is created:
$ make O=build-x86 perf-targz-src-pkg
TAR
cat: ../tools/perf/MANIFEST: No such file or directory
tar: perf-4.1.0-rc8/PERF-VERSION-FILE: Cannot stat: No such file or dir..
tar: Exiting with failure status due to previous errors
Kbuild sets objtree to "." and srctree to ".." The command to output
MANIFEST becomes:
$(cd ..; echo $(cat ../tools/perf/MANIFEST))
Without MANIFEST, the entire kernel source tree is added to the perf
source tarball. The easy fix is removing the unneccesary cd $objtree bit.
Second, PERF-VERSION-FILE gets not added, because in-tree build path is
hardcoded to Makefile:
util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null)
The PERF-VERSION-GEN needs to be run from tools/perf directory, so
we can't just replace the hardcoded "../../" bit the relative $objtree
contents - we need a fully expanded $objtree_full variable to place
PERF-VERSION-FILE to the right place. Also remove the error redirect
to /dev/null which hid the error.
