Hmm... it works. I never paid attention to type casting, because I supposed
it worked fine.

But I have a bigger concern, that strange PF. Anyway, that's what crashes
the kernel.

I do have a "workaround". I can modify the second argument of /*
init_page_allocator() */,
which indicates max_pfn for the allocator. I hardcode max_pfn, and
it's through.
/* periodic_thread */ starts and I get output from serial port.

I am not satisfied with that workaround. Maybe I have to start from /*
start_xen */ so that
I can have an overview of how xen rolls.

Thanks for your advice.
