Including from lockdep.h gives a build error, this patch cures that, but results in the following warning: ../arch/sparc/include/asm/percpu_64.h:7:24: warning: call-clobbered register used for global register variable register unsigned long __local_per_cpu_offset asm("g5"); But i've no idea how to fix that :/ but it does build.
