Hi,

I have a very basic question -- When describing physical memory to the kernel in
prom_init(), should we describe the physical memory region where kernel is loaded or leave it out?  We are using add_memory_region() call to describe physical memory to the kernel.  If we do describe the memory region where kernel is loaded, how will kernel know not to use these pages for User processes?

We are using 2.6.16 on Cavium/Octeon based platform.

Thanks,
JJ
