From fe87f94f341a4b4097285b46f003059b26eb59bf Mon Sep 17 00:00:00 2001 From: Jesper Nilsson Date: Wed, 24 Jun 2009 15:13:41 +0900 Subject: CRIS: Change DEFINE_PER_CPU of current_pgd to be non volatile. The DEFINE_PER_CPU of current_pgd was on CRIS defined using volatile, which is not needed. Remove volatile. Tested on an ARTPEC-3 (CRISv32) board. tj: extern DEFINE_PER_CPU() replaced with DECLARE_PER_CPU() [ Impact: code cleanup ] Signed-off-by: Jesper Nilsson Signed-off-by: Tejun Heo --- arch/cris/include/asm/mmu_context.h | 3 ++- arch/cris/mm/fault.c | 2 +- 2 files changed, 3 insertions(+), 2 deletions(-) (limited to 'arch/cris') diff --git a/arch/cris/include/asm/mmu_context.h b/arch/cris/include/asm/mmu_context.h index 72ba08dcfd1..1d45fd6365b 100644 --- a/arch/cris/include/asm/mmu_context.h +++ b/arch/cris/include/asm/mmu_context.h @@ -17,7 +17,8 @@ extern void switch_mm(struct mm_struct *prev, struct mm_struct *next, * registers like cr3 on the i386 */ -extern volatile DEFINE_PER_CPU(pgd_t *,current_pgd); /* defined in arch/cris/mm/fault.c */ +/* defined in arch/cris/mm/fault.c */ +DECLARE_PER_CPU(pgd_t *, current_pgd); static inline void enter_lazy_tlb(struct mm_struct *mm, struct task_struct *tsk) { diff --git a/arch/cris/mm/fault.c b/arch/cris/mm/fault.c index f925115e325..4a7cdd9ea1e 100644 --- a/arch/cris/mm/fault.c +++ b/arch/cris/mm/fault.c @@ -29,7 +29,7 @@ extern void die_if_kernel(const char *, struct pt_regs *, long); /* current active page directory */ -volatile DEFINE_PER_CPU(pgd_t *,current_pgd); +DEFINE_PER_CPU(pgd_t *, current_pgd); unsigned long cris_signal_return_page; /* -- cgit v1.2.3
