Actually, if anything we should move the *non* __KERNEL_STRICT_NAMES out
of <linux/types.h> into something else, or completely deep-six them.  I
don't know of any libc which wants these anymore, and I think they're
just residual libc5 cruft.

However, if we want <linux/extra_types.h> that's fine with me; but
<linux/types.h> really should be clean, which means doing what
__KERNEL_STRICT_NAMES does now.
