These header files are typically copied from an existing architecture into any new one, slightly modified and then remain untouched until the end of time in the name of ABI stability. To make it easier for future architectures, provide a sane generic version here. In cases where multiple architectures already use identical code, I used the most common version. In cases like stat.h that are more or less broken everywhere, I provide a version that is meant to be ideal for new architectures.
