Manfred please be much more careful next time.
You broke the sparc32 build (missing linux/cpu.h includes), and
you skipped over sparc64 entirely.
I checked in a fix for the sparc32 build failure and the following
sparc64 patch to my sparc-2.6 tree to fix this stuff.
And I'll push this off to Linus shortly.
sparc64: Add missing notify_cpu_starting() call.
Commit e545a6140b698b2494daf0b32107bdcc5e901390 ("kernel/cpu.c: create
a CPU_STARTING cpu_chain notifier") added a notify_cpu_starting()
notifier event, and hit every arch except sparc64.
Fix that missed case.
