This feels a bit odd, but I couldn't really come up with a better way to do it. There already appears to be a workaround for this macro not being defined in userspace, so I figured I'd better leave that in place, since someone is probably using it. The result is that unless you include <asm/fixed_code.h> before <uapi/asm/fixed_code.h> then you'll get the wrong offsets. The only user of <uapi/asm/fixed_code.h> is currently <asm/fixed_code.h>, so it's at least safe for now. There's a CPP error in there to check for this. --- arch/blackfin/include/asm/fixed_code.h | 6 +++++ arch/blackfin/include/uapi/asm/fixed_code.h | 35 ++++++++++++++++------------- 2 files changed, 25 insertions(+), 16 deletions(-) diff --git a/arch/blackfin/include/asm/fixed_code.h b/arch/blackfin/include/asm/fixed_code.h index bc330f0..7e03b9b 100644 --- a/arch/blackfin/include/asm/fixed_code.h +++ b/arch/blackfin/include/asm/fixed_code.h @@ -9,6 +9,12 @@ #ifndef __BFIN_ASM_FIXED_CODE_H__ #define __BFIN_ASM_FIXED_CODE_H__ +#ifdef CONFIG_PHY_RAM_BASE_ADDRESS +#define CONFIG_PHY_RAM_BASE_ADDRESS 0x0 +#endif + +#define PHY_RAM_BASE_ADDRESS CONFIG_PHY_RAM_BASE_ADDRESS + #include <uapi/asm/fixed_code.h> #ifndef __ASSEMBLY__ diff --git a/arch/blackfin/include/uapi/asm/fixed_code.h b/arch/blackfin/include/uapi/asm/fixed_code.h index 3bef1dc..50b70a0 100644 --- a/arch/blackfin/include/uapi/asm/fixed_code.h +++ b/arch/blackfin/include/uapi/asm/fixed_code.h @@ -10,29 +10,32 @@ #ifndef _UAPI__BFIN_ASM_FIXED_CODE_H__ #define _UAPI__BFIN_ASM_FIXED_CODE_H__ - -#ifndef CONFIG_PHY_RAM_BASE_ADDRESS -#define CONFIG_PHY_RAM_BASE_ADDRESS 0x0 +#ifndef PHY_RAM_BASE_ADDRESS +#ifdef __KERNEL__ +#error "Don't include <uapi/asm/fixed_code.h>, include <asm/fixed_code.h>" +#else +#define PHY_RAM_BASE_ADDRESS 0x0 +#endif #endif -#define FIXED_CODE_START (CONFIG_PHY_RAM_BASE_ADDRESS + 0x400) +#define FIXED_CODE_START (PHY_RAM_BASE_ADDRESS + 0x400) -#define SIGRETURN_STUB (CONFIG_PHY_RAM_BASE_ADDRESS + 0x400) +#define SIGRETURN_STUB (PHY_RAM_BASE_ADDRESS + 0x400) -#define ATOMIC_SEQS_START (CONFIG_PHY_RAM_BASE_ADDRESS + 0x410) +#define ATOMIC_SEQS_START (PHY_RAM_BASE_ADDRESS + 0x410) -#define ATOMIC_XCHG32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x410) -#define ATOMIC_CAS32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x420) -#define ATOMIC_ADD32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x430) -#define ATOMIC_SUB32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x440) -#define ATOMIC_IOR32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x450) -#define ATOMIC_AND32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x460) -#define ATOMIC_XOR32 (CONFIG_PHY_RAM_BASE_ADDRESS + 0x470) +#define ATOMIC_XCHG32 (PHY_RAM_BASE_ADDRESS + 0x410) +#define ATOMIC_CAS32 (PHY_RAM_BASE_ADDRESS + 0x420) +#define ATOMIC_ADD32 (PHY_RAM_BASE_ADDRESS + 0x430) +#define ATOMIC_SUB32 (PHY_RAM_BASE_ADDRESS + 0x440) +#define ATOMIC_IOR32 (PHY_RAM_BASE_ADDRESS + 0x450) +#define ATOMIC_AND32 (PHY_RAM_BASE_ADDRESS + 0x460) +#define ATOMIC_XOR32 (PHY_RAM_BASE_ADDRESS + 0x470) -#define ATOMIC_SEQS_END (CONFIG_PHY_RAM_BASE_ADDRESS + 0x480) +#define ATOMIC_SEQS_END (PHY_RAM_BASE_ADDRESS + 0x480) -#define SAFE_USER_INSTRUCTION (CONFIG_PHY_RAM_BASE_ADDRESS + 0x480) +#define SAFE_USER_INSTRUCTION (PHY_RAM_BASE_ADDRESS + 0x480) -#define FIXED_CODE_END (CONFIG_PHY_RAM_BASE_ADDRESS + 0x490) +#define FIXED_CODE_END (PHY_RAM_BASE_ADDRESS + 0x490) #endif /* _UAPI__BFIN_ASM_FIXED_CODE_H__ */ -- 2.4.10 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
