The systemd maintainers decided they don't want to carry sysctl files
for the kernel. So I have attached an alternative patch to
https://bugzilla.redhat.com/show_bug.cgi?id=1209492 (an to this email)
to revert the yama config setting to the upstream default. This fixes
all packages relying on the default ptrace security settings. The patch
is against the f22 kernel git repo (but I saw mention of some alternate
git tree, so please let me know if I should regenerate it against
something else).

Thanks,

Mark
