5 | * There seems to be no way of detecting this automatically from user | |
6 | * space, so 64 bit architectures should override this in their | |
7 | * bitsperlong.h. In particular, an architecture that supports | |
8 | * both 32 and 64 bit user space must not rely on CONFIG_64BIT | |
9 | * to decide it, but rather check a compiler provided macro. | |
