Hm, that's weird - s390 does not build kernel/softirq.o? Hm, it does
- softirq.o is an obj-y object.
s390 does build kernel/softirq.o. However it's anything but obvious to
me how the tracepoint infrastructure works. Too many #ifdefs, #define's
and #undefine's...
I would expect that struct __tracepoint_softirq_entry somehow gets
defined via one of the TRACE_FORMAT macros, no?
Today's next tree also has this failure. Any solution for this problem ?
Thanks
