Thread-topic: Dealing with RAM not starting at 0x00000000
Hi All,

I am working towards porting 2.6.10 kernel on a mips 4kec based board
which has physical memory starting at 0x14000000.
What is the best way to overcome the "hole" from 0x00000000 to
0x14000000 without incuring a huge memory overhead.
(For exception handling there is 4k of RAM kept at 0x00000000 also - but
I guess linux paging need need not be aware of this small RAM)

Any suggestions/pointers are greatly appreciated. 

Thanks,
Sekhar
