From: "Luis R. Rodriguez" <mcgrof@kernel.org>

Add a userspace sandbox to allow easy experimentation and
test extensions with linker tables, section ranges and the
new section core definitions.

The userspace sandbox tries to mimic the Linux kernel development
flow as much as possible, it however relies on and uses libc. Support
is currently only provided to x86_64.

v4: this patch is new in this series -- added to the kenrel as
    suggested by Boris, as otherwise it'd be really hard to keep
    an external userspace repository in sync.

Aren't a bunch of these files exact duplicates of the headers in include/linux?
