The variable became unused when we started storing the CPU specific DSCR value in the PACA structure instead. This patch just removes this extern declaration. It was originally added by the following commit. efcac658: powerpc: Per process DSCR + some fixes (try#4) Signed-off-by: Anshuman Khandual --- arch/powerpc/kernel/process.c | 1 - 1 file changed, 1 deletion(-) diff --git a/arch/powerpc/kernel/process.c b/arch/powerpc/kernel/process.c index febb50d..8005e18 100644 --- a/arch/powerpc/kernel/process.c +++ b/arch/powerpc/kernel/process.c @@ -1112,7 +1112,6 @@ static void setup_ksp_vsid(struct task_struct *p, unsigned long sp) /* * Copy a thread.. */ -extern unsigned long dscr_default; /* defined in arch/powerpc/kernel/sysfs.c */ /* * Copy architecture-specific thread state -- 1.9.3
