Thanks for your help, Helge. binutils-hppa64-linux-gnu gcc-hppa64-linux-gnu binutils-hppa-linux-gnu gcc-hppa-linux-gnu make ARCH=parisc defconfig make ARCH=parisc -j320 CROSS_COMPILE=/usr/bin/hppa-linux-gnu- make ARCH=parisc64 defconfig make ARCH=parisc64 -j320 CROSS_COMPILE=/usr/bin/hppa64-linux-gnu- The below draft patch can fix all build errors. There are some symbol declaration or defination conflict among asm-generic/io.h, asm-generic/iomap.h, asm-generic/pci-iomap.h and asm/io.h. Some of them may need be taken out to be an independent patch since it could be a generic issue if enable GENERIC_IOREMAP. I saw the build error on superH too. diff --git a/arch/parisc/include/asm/io.h b/arch/parisc/include/asm/io.h index 614e21d9749f..879578edf342 100644 --- a/arch/parisc/include/asm/io.h +++ b/arch/parisc/include/asm/io.h @@ -126,7 +126,7 @@ static inline void gsc_writeq(unsigned long long val, unsigned long addr) * I/O memory mapping functions. */ void __iomem * -arch_ioremap(phys_addr_t *paddr, size_t size, unsigned long prot); +arch_ioremap(phys_addr_t *paddr, size_t size, unsigned long *prot_val); #define arch_ioremap arch_ioremap #define _PAGE_IOREMAP (_PAGE_PRESENT | _PAGE_RW | _PAGE_DIRTY | \ @@ -137,6 +137,8 @@ arch_ioremap(phys_addr_t *paddr, size_t size, unsigned long prot); #define ioremap_uc(addr, size) \ ioremap_prot((addr), (size), _PAGE_IOREMAP) +#define ARCH_HAS_IOREMAP_WC + static inline unsigned char __raw_readb(const volatile void __iomem *addr) { return (*(volatile unsigned char __force *) (addr)); @@ -205,6 +207,15 @@ static inline void writeq(unsigned long long q, volatile void __iomem *addr) __raw_writeq((__u64 __force) cpu_to_le64(q), addr); } +#define __raw_readb __raw_readb +#define __raw_readw __raw_readw +#define __raw_readl __raw_readl +#define __raw_readq __raw_readq +#define __raw_writeb __raw_writeb +#define __raw_writew __raw_writew +#define __raw_writel __raw_writel +#define __raw_writeq __raw_writeq + #define readb readb #define readw readw #define readl readl @@ -223,6 +234,9 @@ static inline void writeq(unsigned long long q, volatile void __iomem *addr) #define writel_relaxed(l, addr) writel(l, addr) #define writeq_relaxed(q, addr) writeq(q, addr) +#define memset_io memset_io +#define memcpy_fromio memcpy_fromio +#define memcpy_toio memcpy_toio void memset_io(volatile void __iomem *addr, unsigned char val, int count); void memcpy_fromio(void *dst, const volatile void __iomem *src, int count); void memcpy_toio(volatile void __iomem *dst, const void *src, int count); @@ -244,10 +258,17 @@ extern void eisa_out16(unsigned short data, unsigned short port); extern void eisa_out32(unsigned int data, unsigned short port); #if defined(CONFIG_PCI) +#define inb inb +#define inw inw +#define inl inl extern unsigned char inb(int addr); extern unsigned short inw(int addr); extern unsigned int inl(int addr); +#define outb outb +#define outw outw +#define outl outl +#define inl inl extern void outb(unsigned char b, int addr); extern void outw(unsigned short b, int addr); extern void outl(unsigned int b, int addr); @@ -292,6 +313,13 @@ extern void outsb (unsigned long port, const void *src, unsigned long count); extern void outsw (unsigned long port, const void *src, unsigned long count); extern void outsl (unsigned long port, const void *src, unsigned long count); +#define insb insb +#define insw insw +#define insl insl +#define outsb outsb +#define outsw outsw +#define outsl outsl + /* IO Port space is : BBiiii where BB is HBA number. */ #define IO_SPACE_LIMIT 0x00ffffff @@ -320,6 +348,7 @@ extern void iowrite64be(u64 val, void __iomem *addr); */ #define xlate_dev_mem_ptr(p) __va(p) +#include <asm-generic/io.h> extern int devmem_is_allowed(unsigned long pfn); #endif diff --git a/include/asm-generic/iomap.h b/include/asm-generic/iomap.h index 08237ae8b840..7bf3581ecb0e 100644 --- a/include/asm-generic/iomap.h +++ b/include/asm-generic/iomap.h @@ -26,12 +26,19 @@ * in the low address range.
