From 0aeb3408ca9773283b0ae63771c4b17f39e204df Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 13 Apr 2014 19:43:26 +0100 Subject: ARM: remove global cr_no_alignment cr_no_alignment is really only used by the alignment code. Since we no longer change the setting of cr_alignment after boot, we can localise this to alignment.c Signed-off-by: Russell King --- arch/arm/mm/alignment.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'arch/arm/mm/alignment.c') diff --git a/arch/arm/mm/alignment.c b/arch/arm/mm/alignment.c index 054e995d2f5b..b8cb1a2688a0 100644 --- a/arch/arm/mm/alignment.c +++ b/arch/arm/mm/alignment.c @@ -82,6 +82,7 @@ static unsigned long ai_word; static unsigned long ai_dword; static unsigned long ai_multi; static int ai_usermode; +static unsigned long cr_no_alignment; core_param(alignment, ai_usermode, int, 0600); @@ -979,6 +980,8 @@ static int __init alignment_init(void) ai_usermode = safe_usermode(ai_usermode, false); } + cr_no_alignment = get_cr() & ~CR_A; + hook_fault_code(FAULT_CODE_ALIGNMENT, do_alignment, SIGBUS, BUS_ADRALN, "alignment exception"); -- cgit v1.2.3
