[PATCH 4.8 66/92] x86/build: Fix build with older GCC versions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jan Beulich <JBeulich@xxxxxxxx>

commit a2209b742e6cf978b85d4f31a25a269c3d3b062b upstream.

Older GCC (observed with 4.1.x) doesn't support -Wno-override-init and
also doesn't ignore unknown -Wno-* options.
