I spoke with Tri quickly about this proposal and we agree it's a better fix.

Andrew, would you mind dropping:
https://ozlabs.org/~akpm/mmotm/broken-out/gcov-clang-support-fix.patch

Matthew, would you please send that patch with a commit message? Or
if you would prefer us to send with your suggested-by tag, we can do
that, too. Whichever you prefer, please let me know. Thanks for the
suggestion.
