Date: Tue, 22 Dec 2015 16:12:00 +0530 From: Sudip Mukherjee <sudipm.mukherjee@...il.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, Sudip Mukherjee <sudipm.mukherjee@...il.com> Subject: [PATCH 2/2] m32r: add io*_rep helpers m32r allmodconfig was failing with the error: error: implicit declaration of function 'read' On checking io.h it turned out that 'read' is not defined but 'readb' is defined and 'ioread8' will then obviously mean 'readb'. At the same time some of the helper functions ioreadN_rep() and iowriteN_rep() were missing which also led to the build failure. Signed-off-by: Sudip Mukherjee <sudip@...torindia.org> --- After the change from read to readb the build has been verified with a defconfig build. arch/m32r/include/asm/io.h | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/arch/m32r/include/asm/io.h b/arch/m32r/include/asm/io.h index 61b8931..4b0f5e0 100644 --- a/arch/m32r/include/asm/io.h +++ b/arch/m32r/include/asm/io.h @@ -168,13 +168,21 @@ static inline void _writel(unsigned long l, unsigned long addr) #define writew_relaxed writew #define writel_relaxed writel -#define ioread8 read +#define ioread8 readb #define ioread16 readw #define ioread32 readl #define iowrite8 writeb #define iowrite16 writew #define iowrite32 writel +#define ioread8_rep(p, dst, count) insb((unsigned long)(p), (dst), (count)) +#define ioread16_rep(p, dst, count) insw((unsigned long)(p), (dst), (count)) +#define ioread32_rep(p, dst, count) insl((unsigned long)(p), (dst), (count)) + +#define iowrite8_rep(p, src, count) outsb((unsigned long)(p), (src), (count)) +#define iowrite16_rep(p, src, count) outsw((unsigned long)(p), (src), (count)) +#define iowrite32_rep(p, src, count) outsl((unsigned long)(p), (src), (count)) + #define ioread16be(addr) be16_to_cpu(readw(addr)) #define ioread32be(addr) be32_to_cpu(readl(addr)) #define iowrite16be(v, addr) writew(cpu_to_be16(v), (addr)) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
