Description Peter Robinson 2016-02-12 08:16:57 UTC 
The aarch64 kernel is failing to build due to some issues with gcc 6

Upstream thread discussion is here:

https://gcc.gnu.org/ml/gcc-patches/2016-02/msg00313.html

Final patch for the thread looks to be here:

https://gcc.gnu.org/ml/gcc-patches/2016-02/msg00758.html

This is causing a lot of issues on the mass rebuild. Please review and add relevant patch to Fedora's gcc6 builds

FWIW, that patch was installed into the GCC sources today, so it'll be in the next GCC spin for Fedora 24 from Jakub.
Comment 2 Marcin Juszkiewicz 2016-02-12 10:50:40 UTC 
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=233342 is what got merged into gcc trunk.

I rebuilt gcc with it yesterday and kernel build goes fine with it.
