Might be nicer to do something like this instead of a whole bunch of
__va() operations.  page_to_pfn() is slightly lighter-weight than
virt_to_page() (doesn't really matter at init-time, though).  

start_pfn = rtas_rmo_buf >> PAGE_SHIFT;
end_pfn = (rtas_rmo_buf + RTAS_RMOBUF_MAX) >> PAGE_SHIFT;
for (pfn = start_pfn; pfn < end_pfn; pfn++)
        SetPageReserved(page_to_pfn(pfn));
