* Tue Feb 17 2015 Kyle McMartin <kyle@fedoraproject.org> - 3.20.0-0.rc0.git7.2
- kernel-arm64.patch merge, but leave it off.
- kernel-arm64-fix-psci-when-pg.patch: when -pg (because of ftrace) is enabled
we must explicitly annotate which registers should be assigned, otherwise
gcc will do unexpected things behind our backs.
* Tue Feb 17 2015 Josh Boyer <jwboyer@fedoraproject.org> - 3.20.0-0.rc0.git7.1
- Linux v3.19-7478-g796e1c55717e
- DRM merge
