In swab.h the casting of constants is done away with as well - I simply don't see what the respective comment is concerned about in our environment (sizeof(int) >=3D 4, sizeof(long) >=3D {4,8} depending on architecture, sizeof(long long) >=3D 8). The comment is certainly relevant in more general cases. Excess parentheses are dropped as well, ___swab16()'s local variable is renamed, and __arch__swab16()'s is dropped as being redundant with ___swab16()'s. With that no uses of the type remain, so it moves to linux-compat.h. Signed-off-by: Jan Beulich Reviewed-by: Frediano Ziglio --- I'm unconvinced of the need of the separate ___constant_swab16(). I'm also unconvinced of the need for said constants (that even had casts on them). --- a/xen/include/xen/byteorder/big_endian.h +++ b/xen/include/xen/byteorder/big_endian.h @@ -16,25 +16,25 @@ #define __constant_cpu_to_le32(x) ((__force __le32)___constant_swab32((x))) #define __constant_le32_to_cpu(x) ___constant_swab32((__force __u32)(__le3= 2)(x)) #define __constant_cpu_to_le16(x) ((__force __le16)___constant_swab16((x))) -#define __constant_le16_to_cpu(x) ___constant_swab16((__force __u16)(__le1= 6)(x)) +#define __constant_le16_to_cpu(x) ___constant_swab16((__force uint16_t)(__= le16)(x)) #define __constant_cpu_to_be64(x) ((__force __be64)(__u64)(x)) #define __constant_be64_to_cpu(x) ((__force __u64)(__be64)(x)) #define __constant_cpu_to_be32(x) ((__force __be32)(__u32)(x)) #define __constant_be32_to_cpu(x) ((__force __u32)(__be32)(x)) -#define __constant_cpu_to_be16(x) ((__force __be16)(__u16)(x)) -#define __constant_be16_to_cpu(x) ((__force __u16)(__be16)(x)) +#define __constant_cpu_to_be16(x) ((__force __be16)(uint16_t)(x)) +#define __constant_be16_to_cpu(x) ((__force uint16_t)(__be16)(x)) #define __cpu_to_le64(x) ((__force __le64)__swab64((x))) #define __le64_to_cpu(x) __swab64((__force __u64)(__le64)(x)) #define __cpu_to_le32(x) ((__force __le32)__swab32((x))) #define __le32_to_cpu(x) __swab32((__force __u32)(__le32)(x)) #define __cpu_to_le16(x) ((__force __le16)__swab16((x))) -#define __le16_to_cpu(x) __swab16((__force __u16)(__le16)(x)) +#define __le16_to_cpu(x) __swab16((__force uint16_t)(__le16)(x)) #define __cpu_to_be64(x) ((__force __be64)(__u64)(x)) #define __be64_to_cpu(x) ((__force __u64)(__be64)(x)) #define __cpu_to_be32(x) ((__force __be32)(__u32)(x)) #define __be32_to_cpu(x) ((__force __u32)(__be32)(x)) -#define __cpu_to_be16(x) ((__force __be16)(__u16)(x)) -#define __be16_to_cpu(x) ((__force __u16)(__be16)(x)) +#define __cpu_to_be16(x) ((__force __be16)(uint16_t)(x)) +#define __be16_to_cpu(x) ((__force uint16_t)(__be16)(x)) =20 static inline __le64 __cpu_to_le64p(const __u64 *p) { @@ -52,13 +52,13 @@ static inline __u32 __le32_to_cpup(const { return __swab32p((__u32 *)p);

In swab.h the casting of constants is done away with as well - I simply don't see what the respective comment is concerned about in our environment (sizeof(int) >=3D 4, sizeof(long) >=3D {4,8} depending on architecture, sizeof(long long) >=3D 8). The comment is certainly relevant in more general cases. Excess parentheses are dropped as well, ___swab32()'s local variable is renamed, and __arch__swab32()'s is dropped as being redundant with ___swab32()'s. The masking operation is also dropped from __fswab64(). Signed-off-by: Jan Beulich Reviewed-by: Frediano Ziglio --- I'm unconvinced of the need of the separate ___constant_swab32().

In swab.h the casting of constants is done away with as well - I simply don't see what the respective comment is concerned about in our environment (sizeof(int) >=3D 4, sizeof(long) >=3D {4,8} depending on architecture, sizeof(long long) >=3D 8). The comment is certainly relevant in more general cases. Excess parentheses are dropped as well, ___swab64()'s local variable is renamed, and __arch__swab64()'s is dropped as being redundant with ___swab64()'s. Excessive casts compared to ___{,constant_}swab{16,32}() are also dropped. Much like excessive ones in __fswab64(). Signed-off-by: Jan Beulich Reviewed-by: Frediano Ziglio --- I'm unconvinced of the need of the separate ___constant_swab64(). I'm also unconvinced of the need for some of said constants (that even had casts on them). --- a/xen/include/xen/byteorder/big_endian.h +++ b/xen/include/xen/byteorder/big_endian.h @@ -12,37 +12,37 @@ #include =20 #define __constant_cpu_to_le64(x) ((__force __le64)___constant_swab64((x))) -#define __constant_le64_to_cpu(x) ___constant_swab64((__force __u64)(__le6= 4)(x)) +#define __constant_le64_to_cpu(x) ___constant_swab64((__force uint64_t)(__= le64)(x)) #define __constant_cpu_to_le32(x) ((__force __le32)___constant_swab32((x))) #define __constant_le32_to_cpu(x) ___constant_swab32((__force uint32_t)(__= le32)(x)) #define __constant_cpu_to_le16(x) ((__force __le16)___constant_swab16((x))) #define __constant_le16_to_cpu(x) ___constant_swab16((__force uint16_t)(__= le16)(x)) -#define __constant_cpu_to_be64(x) ((__force __be64)(__u64)(x)) -#define __constant_be64_to_cpu(x) ((__force __u64)(__be64)(x)) +#define __constant_cpu_to_be64(x) ((__force __be64)(uint64_t)(x)) +#define __constant_be64_to_cpu(x) ((__force uint64_t)(__be64)(x)) #define __constant_cpu_to_be32(x) ((__force __be32)(uint32_t)(x)) #define __constant_be32_to_cpu(x) ((__force uint32_t)(__be32)(x)) #define __constant_cpu_to_be16(x) ((__force __be16)(uint16_t)(x)) #define __constant_be16_to_cpu(x) ((__force uint16_t)(__be16)(x)) #define __cpu_to_le64(x) ((__force __le64)__swab64((x))) -#define __le64_to_cpu(x) __swab64((__force __u64)(__le64)(x)) +#define __le64_to_cpu(x) __swab64((__force uint64_t)(__le64)(x)) #define __cpu_to_le32(x) ((__force __le32)__swab32((x))) #define __le32_to_cpu(x) __swab32((__force uint32_t)(__le32)(x)) #define __cpu_to_le16(x) ((__force __le16)__swab16((x))) #define __le16_to_cpu(x) __swab16((__force uint16_t)(__le16)(x)) -#define __cpu_to_be64(x) ((__force __be64)(__u64)(x)) -#define __be64_to_cpu(x) ((__force __u64)(__be64)(x)) +#define __cpu_to_be64(x) ((__force __be64)(uint64_t)(x)) +#define __be64_to_cpu(x) ((__force uint64_t)(__be64)(x)) #define __cpu_to_be32(x) ((__force __be32)(uint32_t)(x)) #define __be32_to_cpu(x) ((__force uint32_t)(__be32)(x)) #define __cpu_to_be16(x) ((__force __be16)(uint16_t)(x)) #define __be16_to_cpu(x) ((__force uint16_t)(__be16)(x)) =20 -static inline __le64 __cpu_to_le64p(const __u64 *p) +static inline __le64 __cpu_to_le64p(const uint64_t *p) { return (__force __le64)__swab64p(p);
