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.
