Fix the following warning(s) (treated as error in W=1): arch/powerpc/kernel/hw_breakpoint.c:106:6: error: no previous prototype for ‘arch_unregister_hw_breakpoint’ arch/powerpc/kernel/hw_breakpoint.c:209:5: error: no previous prototype for ‘hw_breakpoint_handler’ Signed-off-by: Mathieu Malaterre Signed-off-by: Michael Ellerman --- arch/powerpc/include/asm/hw_breakpoint.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/powerpc/include/asm/hw_breakpoint.h b/arch/powerpc/include/asm/hw_breakpoint.h index ac6432d..90c708e 100644 --- a/arch/powerpc/include/asm/hw_breakpoint.h +++ b/arch/powerpc/include/asm/hw_breakpoint.h @@ -66,6 +66,7 @@ extern int hw_breakpoint_exceptions_notify(struct notifier_block *unused, unsigned long val, void *data); int arch_install_hw_breakpoint(struct perf_event *bp); void arch_uninstall_hw_breakpoint(struct perf_event *bp); +void arch_unregister_hw_breakpoint(struct perf_event *bp); void hw_breakpoint_pmu_read(struct perf_event *bp); extern void flush_ptrace_hw_breakpoint(struct task_struct *tsk); @@ -82,6 +83,7 @@ static inline void hw_breakpoint_disable(void) __set_breakpoint(&brk); } extern void thread_change_pc(struct task_struct *tsk, struct pt_regs *regs); +int hw_breakpoint_handler(struct die_args *args); #else /* CONFIG_HAVE_HW_BREAKPOINT */ static inline void hw_breakpoint_disable(void) { } -- 2.7.4
