From 8e31c2ac1101b09ad6c6d3539b032d312cc3302b Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 11 Feb 2008 10:50:21 +0100 Subject: x86: CPA: remove BUG_ON for LRU/Compound pages New implementation does not use lru for anything so there is no need to reject pages that are in the LRU. Similar for compound pages (which were checked because they also use page->lru) [ tglx@linutronix.de: removed unused variable ] Signed-off-by: Andi Kleen Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- arch/x86/mm/pageattr.c | 5 ----- 1 file changed, 5 deletions(-) (limited to 'arch') diff --git a/arch/x86/mm/pageattr.c b/arch/x86/mm/pageattr.c index 3ee14996c829..e2a74ea11a53 100644 --- a/arch/x86/mm/pageattr.c +++ b/arch/x86/mm/pageattr.c @@ -513,7 +513,6 @@ static int __change_page_attr(struct cpa_data *cpa, int primary) unsigned long address = cpa->vaddr; int do_split, err; unsigned int level; - struct page *kpte_page; pte_t *kpte, old_pte; repeat: @@ -532,10 +531,6 @@ repeat: return -EINVAL; } - kpte_page = virt_to_page(kpte); - BUG_ON(PageLRU(kpte_page)); - BUG_ON(PageCompound(kpte_page)); - if (level == PG_LEVEL_4K) { pte_t new_pte; pgprot_t new_prot = pte_pgprot(old_pte); -- cgit v1.2.3
