From 4b2e0162e4ab1a976eec0a36ca0bd920b02bfff3 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 3 Aug 2016 17:33:32 +0200 Subject: [PATCH] fs/proc: Add compiler check for -Wno-override-init to support gcc < 4.2 With gcc < 4.2 (e.g. 4.1.2): CC fs/proc/task_mmu.o cc1: error: unrecognized command line option "-Wno-override-init" To fix this, only enable the compiler option when it is actually supported by the compiler.
