[GIT PULL 00/11] perf/core improvements and fixes

Show all headers | View raw

Hi Ingo,

	Please consider pulling,

- Arnaldo

Build news:

Now the 16.04-x-armhf and 16.04-x-powerpc64 cross build docker images have libz
and libelf cross built from sources, so that we can cover cross build testing
more of the codebase.

In those images objtool is not built, as checking powerpc and arm binaries is
not supported, so trying to build it will end up in linker errors.
