Hi all,
After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:
kernel/signal.c: In function 'ptrace_stop':
kernel/signal.c:1860:3: error: implicit declaration of function 'synchronize_user_stack' [-Werror=implicit-function-declaration]
Presumably caused by commit d550bbd40c0e ("Disintegrate asm/system.h for
Sparc").
I added this patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Fri, 30 Mar 2012 14:26:24 +1100
Subject: [PATCH] sparc: fix fallout from system.h split
Fixes this build error:
kernel/signal.c: In function 'ptrace_stop':
kernel/signal.c:1860:3: error: implicit declaration of function 'synchronize_user_stack' [-Werror=implicit-function-declaration]
