  concurrency fixes
- Added public key of "Frank Ch. Eigler <fche@elastic.org>",
  since he signed the new package

Subject: adjust build source dir for SuSE packaging
References: bnc#796574
kernel-$flavor:
/lib/modules/$version-$flavor
kernel-$flavor-devel: requires kernel-source
/usr/src/linux-$version-obj/$arch/$flavor
/lib/modules/$version-$flavor/build -> /usr/src/linux-$version-obj/$arch/$flavor
/lib/modules/$version-$flavor/source -> /usr/src/linux-$version [kernel-source]
kernel-flavor-debugsource:
/usr/src/debug/kernel-$flavor/
linux-obj/ {corresponds to /lib/modules/$version-$flavor/build}
linux-3.0/ {mirrors kernel-source}
DW_AT_comp_dir points to debugsource/linux-obj directory but internal trace
headers are only found in linux-3.0. Regardless, we don't want to require
debugsource as devel already requires kernel-source which provides the
necessary headers.
