Matthew Wilcox f8d5d0cc14 xarray: Add definition of struct xarray
This is a direct replacement for struct radix_tree_root.  Some of the
struct members have changed name; convert those, and use a #define so
that radix_tree users continue to work without change.

Matthew Wilcox ebb9a9aedb tools: add WARN_ON_ONCE
Patch series "Radix tree patches for 4.10", v3.

Mostly these are improvements; the only bug fixes in here relate to
multiorder entries (which are unused in the 4.9 tree).

This patch (of 32):

The radix tree uses its own buggy WARN_ON_ONCE.  Replace it with the
definition from asm-generic/bug.h

Matthew Wilcox 1366c37ed8 radix tree test harness
This code is mostly from Andrew Morton and Nick Piggin; tarball downloaded
from http://ozlabs.org/~akpm/rtth.tar.gz with sha1sum
0ce679db9ec047296b5d1ff7a1dfaa03a7bef1bd

Some small modifications were necessary to the test harness to fix the
build with the current Linux source code.

I also made minor modifications to automatically test the radix-tree.c
and radix-tree.h files that are in the current source tree, as opposed
to a copied and slightly modified version.  I am sure more could be done
to tidy up the harness, as well as adding more tests.
