From 69d15f6b352a681f1db9bc70219a3e8e9d503dbf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 4 Jun 2007 15:15:50 +1000 Subject: [PATCH] [POWERPC] Consolidate sys_sigaltstack sys_sigaltstack is the same on 32bit and 64 and we can consolidate it to signal.c. The only difference is that the 32bit code uses ints for the unused register paramaters and 64bit unsigned long. I've changed it to unsigned long because it's the same width on 32bit. (I also wonder who came up with this awkward calling convention.. :)) Signed-off-by: Christoph Hellwig Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras --- arch/powerpc/kernel/signal.c | 7 +++++++ arch/powerpc/kernel/signal_32.c | 8 -------- arch/powerpc/kernel/signal_64.c | 8 -------- include/asm-powerpc/syscalls.h | 7 ------- 4 files changed, 7 insertions(+), 23 deletions(-) diff --git a/arch/powerpc/kernel/signal.c b/arch/powerpc/kernel/signal.c index 88a12544e8..325d260abd 100644 --- a/arch/powerpc/kernel/signal.c +++ b/arch/powerpc/kernel/signal.c @@ -63,3 +63,10 @@ void check_syscall_restart(struct pt_regs *regs, struct k_sigaction *ka, regs->ccr |= 0x10000000; } } + +long sys_sigaltstack(const stack_t __user *uss, stack_t __user *uoss, + unsigned long r5, unsigned long r6, unsigned long r7, + unsigned long r8, struct pt_regs *regs) +{ + return do_sigaltstack(uss, uoss, regs->gpr[1]); +} diff --git a/arch/powerpc/kernel/signal_32.c b/arch/powerpc/kernel/signal_32.c index e5cc803476..f5713bfcc5 100644 --- a/arch/powerpc/kernel/signal_32.c +++ b/arch/powerpc/kernel/signal_32.c @@ -253,14 +253,6 @@ long sys_sigsuspend(old_sigset_t mask) return -ERESTARTNOHAND; } -#ifdef CONFIG_PPC32 -long sys_sigaltstack(const stack_t __user *uss, stack_t __user *uoss, int r5, - int r6, int r7, int r8, struct pt_regs *regs) -{ - return do_sigaltstack(uss, uoss, regs->gpr[1]); -} -#endif - long sys_sigaction(int sig, struct old_sigaction __user *act, struct old_sigaction __user *oact) { diff --git a/arch/powerpc/kernel/signal_64.c b/arch/powerpc/kernel/signal_64.c index 5d2faf0fbf..817f1cf4a4 100644 --- a/arch/powerpc/kernel/signal_64.c +++ b/arch/powerpc/kernel/signal_64.c @@ -66,14 +66,6 @@ struct rt_sigframe { char abigap[288]; } __attribute__ ((aligned (16))); -long sys_sigaltstack(const stack_t __user *uss, stack_t __user *uoss, unsigned long r5, - unsigned long r6, unsigned long r7, unsigned long r8, - struct pt_regs *regs) -{ - return do_sigaltstack(uss, uoss, regs->gpr[1]); -} - - /* * Set up the sigcontext for the signal frame. */ diff --git a/include/asm-powerpc/syscalls.h b/include/asm-powerpc/syscalls.h index c2fe79d4f9..b3ca41fc8b 100644 --- a/include/asm-powerpc/syscalls.h +++ b/include/asm-powerpc/syscalls.h @@ -43,16 +43,9 @@ asmlinkage long ppc_newuname(struct new_utsname __user * name); asmlinkage long sys_rt_sigsuspend(sigset_t __user *unewset, size_t sigsetsize); - -#ifndef __powerpc64__ -asmlinkage long sys_sigaltstack(const stack_t __user *uss, - stack_t __user *uoss, int r5, int r6, int r7, int r8, - struct pt_regs *regs); -#else /* __powerpc64__ */ asmlinkage long sys_sigaltstack(const stack_t __user *uss, stack_t __user *uoss, unsigned long r5, unsigned long r6, unsigned long r7, unsigned long r8, struct pt_regs *regs); -#endif /* __powerpc64__ */ #endif /* __KERNEL__ */ #endif /* __ASM_POWERPC_SYSCALLS_H */ -- 2.39.5
