[ 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.
