#     powerpc: Enable kcov
#     
#     kcov provides kernel coverage data that's useful for fuzzing tools like
#     syzkaller.
#     
#     Wire up kcov support on powerpc. Disable kcov instrumentation on the same
#     files where we currently disable gcov and UBSan instrumentation, plus some
#     additional exclusions which appear necessary to boot on book3e machines.
