The MANIFEST file is used in the following Makefile targets:
$ make tar{,gz,bz2,xz}-src-pkg
to generate an archive that can be used outside the kernel tree. It
contains entries that are used for pathspec filtering 'git archive',
which ultimately generates the archive. Remove the stale
entries (non-existent paths) by running:
$ while read l; do file $l; done <tools/perf/MANIFEST | grep ERROR
in the toplevel kernel tree.

Thanks to David for pointing out that the MANIFEST is used by
scripts/package. This patch safely removes the stale entries.

Did you create a tarfile after this change, unpack it somewhere out of
three and then verify perf builds?

Yeah, it builds fine. In fact, the archive generated from the current
upstream is broken.

Could you please describe how it is broken?

Oh, I meant the torvalds/linux.git master.
$ git describe
v3.12-rc2-83-g4b97280
$ make perf-tarbz2-src-pkg
TAR
$ tar tf perf-3.12.0-rc2.tar.bz2 | grep tools
perf-3.12.0-rc2/tools/
As you can see, the tools/perf directory is completely missing. With
my patch applied, the archive is totally fine (and perf builds and
runs fine). I suspect the issue has to do with non-existent paths
given as the pathspec filtering argument to 'git archive'. Note that
I'm running the latest git HEAD.
Thanks.
