From bb152f53120d66c98c1f16518407df6a84f23714 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Fri, 6 Jan 2006 00:12:05 -0800 Subject: [PATCH] x86/x86_64: mark rodata section read-only: make some datastructures const Mark some key kernel datastructures readonly. This patch was previously posted on Jun 28th but was back then not merged because nothing was enforcing rodata anyway.. well that changed now :) Patch by Christoph Lameter and Dave Jones Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Cc: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/x86_64/kernel/syscall.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/x86_64/kernel/syscall.c') diff --git a/arch/x86_64/kernel/syscall.c b/arch/x86_64/kernel/syscall.c index e263685f864c..7c176b3edde0 100644 --- a/arch/x86_64/kernel/syscall.c +++ b/arch/x86_64/kernel/syscall.c @@ -19,7 +19,7 @@ typedef void (*sys_call_ptr_t)(void); extern void sys_ni_syscall(void); -sys_call_ptr_t sys_call_table[__NR_syscall_max+1] __cacheline_aligned = { +const sys_call_ptr_t sys_call_table[__NR_syscall_max+1] = { /* Smells like a like a compiler bug -- it doesn't work when the & below is removed. */ [0 ... __NR_syscall_max] = &sys_ni_syscall, #include -- cgit v1.2.3
