#ifndef __BITS_PER_LONG
* In order to keep safe and avoid regression, only unify uapi
* bitsperlong.h for some archs which are using newer toolchains
* that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.
* See the following link for more info:
#if defined(__CHAR_BIT__) && defined(__SIZEOF_LONG__)
#define __BITS_PER_LONG (__CHAR_BIT__ * __SIZEOF_LONG__)
* There seems to be no way of detecting this automatically from user
* space, so 64 bit architectures should override this in their
* bitsperlong.h. In particular, an architecture that supports
* both 32 and 64 bit user space must not rely on CONFIG_64BIT
* to decide it, but rather check a compiler provided macro.
