From d6e6a27d960f9f07aef0b979c49c6736ede28f75 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 30 Nov 2021 14:13:16 +0000 Subject: tools: Fix math.h breakage 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.

These are all unused after the liblockdep code was removed in commit 7246f4dcaccc ("tools/lib/lockdep: drop liblockdep"). Note that there are still headers that were originally created for liblockdep, that still have liblockdep references, but they are used by other tools/ code at this point.
