I know nothing about <asm/segment.h> but this generic statement is
simply not true.

There are perfectly valid uses of kernel headers from userspace. For
example if a program uses the netlink interface, it should include
<linux/netlink.h>. It's the interface definition after all.

Glibc headers also include <linux/*> and <asm/*> in quite few places.
