asm-generic: introduce asm/bitsperlong.h

2009-06-11T19:02:14Z

This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms. Signed-off-by: Remis Lima Baima Signed-off-by: Arnd Bergmann

asm-generic/int-ll64.h: always provide __{s,u}64

2008-07-25T17:53:27Z

Several compilers offer "long long" without claiming to support C99. Considering how frequent __s64/__u64 are used our userspace headers are anyway unusable without __s64/__u64 available. Always offer __s64/__u64 to non-gcc non-C99 compilers - if they provide "long long" that makes the headers compiling and if they don't they are anyway screwed. Signed-off-by: Adrian Bunk Acked-by: H.

types: add C99-style constructors to

2008-05-02T23:18:42Z

Add C99-style constructor macros for fixed types to . Since Linux uses names like "u64" instead of "uint64_t", the constructor macros are called U64_C() instead of UINT64_C() and so forth. These macros allow specific sizes to be specified as U64_C(0x123456789abcdef), without gcc issuing warnings as it will if one writes (u64)0x123456789abcdef. When used from assembly, these macros pass their argument unchanged. Signed-off-by: H. Peter Anvin

types: create

2008-05-02T23:18:19Z

This creates two generic files with common integer definitions; one where 64 bits is "long" (most 64-bit architectures) and one where 64 bits is "long long" (all 32-bit architectures and x86-64.)
