I figured out a solution to my problem: It seems I need to mem_map_reserve all pages which I kmalloc. Once I do this, they are mappable to user space.

I've also tried look at the phys > addr (offset from 0x1f1f0000) and that too is zeros. Have a look at the process /proc/<pid>/maps on the host to see what it has mapped in at 0x404e9000. The offset column is the offset into the VM file, which is the physical address mapped in to that virtual address.
