I agree, but as of now, I do not have any better solution. If & when  
I will implement kernel page table for memory above 2000_0000, I plan  
to give it a through mapping. That is to say, 4000_0000 physical  
mapped to 4000_0000 virtual. In that case the page.h __pa/__va macros  
stand a chance (^_^;)
If somebody has already done kernel page table implementation, could  
you please pass on the relevant patch? Thanks.
