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

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.

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.)Signed-off-by: H. Peter Anvin
