From: Tejun Heo Date: Sun, 30 Oct 2005 23:02:42 +0000 (-0800) Subject: [PATCH] vm: remove unused/broken page_pte[_prot] macros X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1426d7a81dea8e9d85f9d69de85ab04ba37018ab;p=openwrt%2Fstaging%2Fblogic.git [PATCH] vm: remove unused/broken page_pte[_prot] macros This patch removes page_pte_prot and page_pte macros from all architectures. Some architectures define both, some only page_pte (broken) and others none. These macros are not used anywhere. page_pte_prot(page, prot) is identical to mk_pte(page, prot) and page_pte(page) is identical to page_pte_prot(page, __pgprot(0)). * The following architectures define both page_pte_prot and page_pte arm, arm26, ia64, sh64, sparc, sparc64 * The following architectures define only page_pte (broken) frv, i386, m32r, mips, sh, x86-64 * All other architectures define neither Signed-off-by: Tejun Heo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/include/asm-arm/pgtable.h b/include/asm-arm/pgtable.h index 366bafbdfbb1..5a0d19b466b0 100644 --- a/include/asm-arm/pgtable.h +++ b/include/asm-arm/pgtable.h @@ -397,9 +397,6 @@ static inline pte_t *pmd_page_kernel(pmd_t pmd) #define pgd_clear(pgdp) do { } while (0) #define set_pgd(pgd,pgdp) do { } while (0) -#define page_pte_prot(page,prot) mk_pte(page, prot) -#define page_pte(page) mk_pte(page, __pgprot(0)) - /* to find an entry in a page-table-directory */ #define pgd_index(addr) ((addr) >> PGDIR_SHIFT) diff --git a/include/asm-arm26/pgtable.h b/include/asm-arm26/pgtable.h index f602cf572411..a590250277f8 100644 --- a/include/asm-arm26/pgtable.h +++ b/include/asm-arm26/pgtable.h @@ -98,8 +98,6 @@ extern struct page *empty_zero_page;
