Good:

- rpmlint checks return:

mcelog.spec:28: W: rpm-buildroot-usage %build rm -rf $RPM_BUILD_ROOT
$RPM_BUILD_ROOT should not be touched during %build or %prep stage, as it may
break short circuit builds.

mcelog.spec:29: W: rpm-buildroot-usage %build mkdir -p $RPM_BUILD_ROOT/%{_sysconfdir}
$RPM_BUILD_ROOT should not be touched during %build or %prep stage, as it may
break short circuit builds.

mcelog.spec:30: W: rpm-buildroot-usage %build mkdir -p $RPM_BUILD_ROOT/%{_sbindir}
$RPM_BUILD_ROOT should not be touched during %build or %prep stage, as it may
break short circuit builds.

mcelog.spec:31: W: rpm-buildroot-usage %build mkdir -p $RPM_BUILD_ROOT/%{_mandir}
$RPM_BUILD_ROOT should not be touched during %build or %prep stage, as it may
break short circuit builds.

mcelog.spec:39: E: hardcoded-library-path in $RPM_BUILD_ROOT/lib/systemd/system
A library path is hardcoded to one of the following paths: /lib, /usr/lib. It
should be replaced by something like /%{_lib} or %{_libdir}.

mcelog.spec:50: E: hardcoded-library-path in $RPM_BUILD_ROOT/lib/systemd/system/mcelog.service
A library path is hardcoded to one of the following paths: /lib, /usr/lib. It
should be replaced by something like /%{_lib} or %{_libdir}.

mcelog.spec:82: E: hardcoded-library-path in /lib/systemd/system/mcelog.service
A library path is hardcoded to one of the following paths: /lib, /usr/lib. It
should be replaced by something like /%{_lib} or %{_libdir}.

Fix.  For /lib/systemd/system, use %{_unitdir}.

mcelog.spec: W: invalid-url Source0: mcelog-6e4e2a00.tar.bz2
The value should be a valid, public HTTP, HTTPS, or FTP URL.

Fix if there's a URL for git checkouts.

mcelog.x86_64: W: summary-ended-with-dot C Tool to translate x86-64 CPU Machine Check Exception data.
Summary ends with a dot.

Fix.

mcelog.x86_64: W: spelling-error %description -l en_US cron -> corn, con, crone
The value of this tag appears to be misspelled. Please double-check.

Ignore.

Lots of wrong fsf address, file a bug upstream.

You also need the following requires:

Requires(post): systemd-units
Requires(preun): systemd-units
Requires(postun): systemd-units


Other than the things from rpmlint and the requires, no major issues.  Let me know if you'd like me to commit anything.

Done.
