I think this should _actually_ be ready to go this time, the buildbot found
some errors in arches that I didn't test for.

Changes since v4 (<1446579994-9937-1-git-send-email-palmer@dabbelt.com>)

 * #9 was changed to work on arm by moving the enum to an in-kernel header
   file.

 * #13 was added, this fixes a problem on blackfin.

Changes since v3 (<1442271047-4908-1-git-send-email-palmer@dabbelt.com>)

 * #4 is very different: rather than defining a canonical value for
   MAP_UNINITIALIZED, it just punts on the problem and lets arch maintainers
   deal with it.  There's still an #ifndef MAP_UNINITIALIZED in there, but that
   shouldn't get triggered by anything because the arch headers should set it
   to whatever they actually want.

 * #11 defines MAX_RAW_MINORS to 2^20 instead of 2^16.

 * #13 moves the variable around a bit so it gets initialized.  I forgot I was
   in perl and not C :).

Changes since v2 (<1441832902-28993-1-git-send-email-palmer@dabbelt.com>)

 * Patch set renamed.

 * #2 is rewritten to use sys_ni.c instead of an #ifdef

 * #3, #6, #8, #9, #10, and #11 no longer use "#ifdef __KERNEL__" but
   have instead moved the offending lines to the correct, kernel-only
   files.

 * #4 has been rewritten to always define MAP_UNINITIALIZED to
   non-zero, rather than defining it to zero when in userspace.

 * #5 got a whole lot longer -- rather than just always hiding these
   fields from userspace, there is now a second "struct
   elf_fdpic_prstatus" structure.  This should allow userspace to
   parse core dumps correctly.

 * Rebased onto 9c488de24f7264f08d341024bffdd637b4d04c96.

Changes since v1 (<1441152610-22566-1-git-send-email-palmer@dabbelt.com>)

 * All patches but #1 were added.
