7fa3d78319 Automatically replace kernel_(scno|ureg)_t with kernel_ulong_t
Remove temporary types created for transition from long
to kernel_ulong_t.

Automatically replace kernel_scno_t and kernel_ureg_t with
kernel_ulong_t using
$ git grep -El 'kernel_(scno|ureg)_t' |
  xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'

* kernel_types.h (kernel_scno_t, kernel_ureg_t): Remove.
All users updated.

Dr. David Alan Gilbert
5d1216a56b Decode UFFDIO_* ioctls
Decode the ioctls associated with the userfaultfd fd.
Note that they tend to read from and also return result in it's data
structure.

* configure.ac (AC_CHECK_HEADERS): Add linux/userfaultfd.h.
* userfaultfd.c [HAVE_LINUX_USERFAULTFD_H]: Add ioctl decoder.
* defs.h (uffdio_ioctl): New prototype.
* ioctl.c (ioctl_decode) [HAVE_LINUX_USERFAULTFD_H]: Wire in
uffdio_ioctl.
* xlat/uffd_*.in: Create flag xlat for all the IOCTLs.

38a34c9349 Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't.  This
change fixes the inconsistency by adding missing copyright headers.

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
