[GIT PULL 00/12] perf/urgent fixes
From: Arnaldo Carvalho de Melo
Date: Wed Jan 04 2017 - 13:14:11 EST
Hi Ingo,
Please consider pulling,
- Arnaldo
Test results at the end of this message, as usual, news about it:
Has two new targets, debian:experimental-x-mipsel and
debian:experimental-x-arm64.
Those use debian's multi-arch packages allowing cross building more than with
the other crossbuild containers.
This still doesn't generate a full featured tool, as there are some buggy
multi-arch packages, such as the devel packages for perl, gtk2, etc.
The following changes since commit 3705b97505bcbf6440f38119c0e7d6058f585b54:
Merge tag 'perf-urgent-for-mingo-20161222' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent (2016-12-23 20:23:29 +0100)
are available in the git repository at:
