Having asm/cmpxchg.h pull in linux/bug.h is problematic because this ends up pulling in the atomic bitops which themselves may be built on top of atomic.h and cmpxchg.h. Instead, just include build_bug.h for the definition of BUILD_BUG. Signed-off-by: Will Deacon <redacted> --- arch/arm64/include/asm/cmpxchg.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
