In order to break a header dependency between lockdep and task_struct,
I need per-cpu stuff from lockdep.
Including <asm/percpu.h> 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.
