Subject: [RESEND PATCH 1/2] ppc: Fix compiler warning in ptrace.c [-Wno-array-bounds]
Date: Sat,  7 May 2011 18:54:34 +0300	[thread overview]
Message-ID: <1304783674-3977-1-git-send-email-psomas@cslab.ece.ntua.gr> (raw)
In-Reply-To: <m2oc3eh744.fsf@igel.home>

The trick used to bypass the thread_struct fpr array in order to access the
struct fpscr, in arch/powerpc/kernel/ptrace.c, can trigger an "array subscript
is above array bounds [-Werror=array-bounds]" warning.

Add -Wno-array-bounds to CFLAGS_ptrace.o, in arch/powerpc/kernel/Makefile to
slience this warning.
