From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
[ Upstream commit d6e6a27d960f9f07aef0b979c49c6736ede28f75 ]
Commit 98e1385ef24b ("include/linux/radix-tree.h: replace kernel.h with
the necessary inclusions") broke the radix tree test suite in two
different ways; first by including math.h which didn't exist in the
tools directory, and second by removing an implicit include of
spinlock.h before lockdep.h. Fix both issues.
