Fix that, and also fix up an instance where page_to_virt was expected to return 'unsigned long', and drop another instance that was entirely unused (page_to_bus) Signed-off-by: Ard Biesheuvel --- arch/nios2/include/asm/io.h | 1 - arch/nios2/include/asm/page.h | 2 +- arch/nios2/include/asm/pgtable.h | 2 +- 3 files changed, 2 insertions(+), 3 deletions(-) diff --git a/arch/nios2/include/asm/io.h b/arch/nios2/include/asm/io.h index c5a62da22cd2..ce072ba0f8dd 100644 --- a/arch/nios2/include/asm/io.h +++ b/arch/nios2/include/asm/io.h @@ -50,7 +50,6 @@ static inline void iounmap(void __iomem *addr) /* Pages to physical address... */ #define page_to_phys(page) virt_to_phys(page_to_virt(page)) -#define page_to_bus(page) page_to_virt(page) /* Macros used for converting between virtual and physical mappings. */ #define phys_to_virt(vaddr) \ diff --git a/arch/nios2/include/asm/page.h b/arch/nios2/include/asm/page.h index 4b32d6fd9d98..c1683f51ad0f 100644 --- a/arch/nios2/include/asm/page.h +++ b/arch/nios2/include/asm/page.h @@ -84,7 +84,7 @@ extern struct page *mem_map; ((void *)((unsigned long)(x) + PAGE_OFFSET - PHYS_OFFSET)) #define page_to_virt(page) \ - ((((page) - mem_map) << PAGE_SHIFT) + PAGE_OFFSET) + ((void *)(((page) - mem_map) << PAGE_SHIFT) + PAGE_OFFSET) # define pfn_to_kaddr(pfn) __va((pfn) << PAGE_SHIFT) # define pfn_valid(pfn) ((pfn) >= ARCH_PFN_OFFSET && \ diff --git a/arch/nios2/include/asm/pgtable.h b/arch/nios2/include/asm/pgtable.h index a213e8c9aad0..298393c3cb42 100644 --- a/arch/nios2/include/asm/pgtable.h +++ b/arch/nios2/include/asm/pgtable.h @@ -209,7 +209,7 @@ static inline void set_pte(pte_t *ptep, pte_t pteval) static inline void set_pte_at(struct mm_struct *mm, unsigned long addr, pte_t *ptep, pte_t pteval) { - unsigned long paddr = page_to_virt(pte_page(pteval)); + unsigned long paddr = (unsigned long)page_to_virt(pte_page(pteval)); flush_dcache_range(paddr, paddr + PAGE_SIZE); set_pte(ptep, pteval); -- 2.5.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
