Signed-off-by: Chris Metcalf --- Mike, thanks for the pointer to the hweight issue. Since we are using __builtin_popcount() and the compiler can do constant propagation, etc., with it at compile-time, this is less critical, but it seems like the easiest way to get the definitions of the HWEIGHT macros. arch/tile/include/asm/bitops.h | 9 +++++---- 1 files changed, 5 insertions(+), 4 deletions(-) diff --git a/arch/tile/include/asm/bitops.h b/arch/tile/include/asm/bitops.h index 84600f3..6832b4b 100644 --- a/arch/tile/include/asm/bitops.h +++ b/arch/tile/include/asm/bitops.h @@ -98,26 +98,27 @@ static inline int fls64(__u64 w) return (sizeof(__u64) * 8) - __builtin_clzll(w); } -static inline unsigned int hweight32(unsigned int w) +static inline unsigned int __arch_hweight32(unsigned int w) { return __builtin_popcount(w); } -static inline unsigned int hweight16(unsigned int w) +static inline unsigned int __arch_hweight16(unsigned int w) { return __builtin_popcount(w & 0xffff); } -static inline unsigned int hweight8(unsigned int w) +static inline unsigned int __arch_hweight8(unsigned int w) { return __builtin_popcount(w & 0xff); } -static inline unsigned long hweight64(__u64 w) +static inline unsigned long __arch_hweight64(__u64 w) { return __builtin_popcountll(w); } +#include #include #include #include -- 1.6.5.2 -- 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/
