- * Original kernel header comment:
- *
- * Kernel pointers have redundant information, so we can use a
- * scheme where we can return either an error code or a normal
- * pointer with the same return value.
- *
- * This should be a per-architecture thing, to allow different
- * error and pointer decisions.
- *
- * Userspace note:
- * The same principle works for userspace, because 'error' pointers
- * fall down to the unused hole far from user space, as described
- * in Documentation/x86/x86_64/mm.txt for x86_64 arch:
- *
- * 0000000000000000 - 00007fffffffffff (=47 bits) user space, different per mm hole caused by [48:63] sign extension
- * ffffffffffe00000 - ffffffffffffffff (=2 MB) unused hole
- *
- * It should be the same case for other architectures, because
- * this code is used in generic kernel code.
