Hi, Arnaldo
I found something weird about perf/core branch on your repository.
(I don't know whether it is just my illusion or not)
I can't pull new commits on top of perf-core-for-mingo-20160606
by normal way as below
# git remote show acme
* remote acme
Fetch URL: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git
# git log --oneline
edb13ed tools lib bpf: Rename set_private() to set_priv()
be834ff tools lib bpf: Make bpf_program__get_private() use IS_ERR()
...
# git pull acme perf/core
From git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
* branch perf/core -> FETCH_HEAD
Already up-to-date.
And then nothing changed, I didn't also find new commits
and new tag 'perf-core-for-mingo-20160607'.
However, if using tag perf-core-for-mingo-20160607,
I can get new commits from your repository as below.
# git fetch acme --tags

* [new tag] v2.6.11 -> v2.6.11
* [new tag] v2.6.11-tree -> v2.6.11-tree
But there is a strange thing about git branch.
I can't find which branch is that have tag perf-core-for-mingo-20160607
like below.
# git branch -a --contains perf-core-for-mingo-20160607
As the final outcome, I got new commits on top of
perf-core-for-mingo-20160606 directly using a tag
'perf-core-for-mingo-20160607' as below.
# git reset --hard perf-core-for-mingo-20160607
HEAD is now at 057fbfb perf callchain: Support aarch64 cross-platform
But isn't it a problem ?
Just use a tag?
Thanks,
Taeung

perf callchain: Support aarch64 cross-platform (2016-06-07 15:13:35 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
in one machine and then doing analysis in another machine of a different
hardware architecture. This enables, for instance, to do:
perf record -a --call-graph dwarf
on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation. (He Kuang)
- Fix crash in build_id_cache__kallsyms_path(), recent regression (Wang Nan)
Infrastructure:
- Make tools/lib/bpf use the IS_ERR return facility consistently and also stop
using the _get_ term for non-reference count methods (Arnaldo Carvalho de
Melo)
- 'perf config' refactorings (Taeung Song)
