From f928c16dbfaff447c637d8c22c29a642be0044f1 Mon Sep 17 00:00:00 2001 From: James Morse Date: Mon, 5 Sep 2016 09:43:04 +0100 Subject: [PATCH] arm64: Drop generic xlate_dev_mem_{k,}ptr() The code that provides /dev/mem uses xlate_dev_mem_{k,}ptr() to avoid making a cachable mapping of a non-cachable area on ia64. On arm64 we do this via phys_mem_access_prot() instead, but provide dummy versions of xlate_dev_mem_{k,}ptr(). These are the same as those in asm-generic/io.h, which we include from asm/io.h Signed-off-by: James Morse Signed-off-by: Will Deacon --- arch/arm64/include/asm/io.h | 11 ----------- 1 file changed, 11 deletions(-) diff --git a/arch/arm64/include/asm/io.h b/arch/arm64/include/asm/io.h index 9b6e408cfa51..ce20741b2cb5 100644 --- a/arch/arm64/include/asm/io.h +++ b/arch/arm64/include/asm/io.h @@ -184,17 +184,6 @@ extern void __iomem *ioremap_cache(phys_addr_t phys_addr, size_t size); #define iowrite32be(v,p) ({ __iowmb(); __raw_writel((__force __u32)cpu_to_be32(v), p); }) #define iowrite64be(v,p) ({ __iowmb(); __raw_writeq((__force __u64)cpu_to_be64(v), p); }) -/* - * Convert a physical pointer to a virtual kernel pointer for /dev/mem - * access - */ -#define xlate_dev_mem_ptr(p) __va(p) - -/* - * Convert a virtual cached pointer to an uncached pointer - */ -#define xlate_dev_kmem_ptr(p) p - #include /* -- 2.20.1
