Question on mmap(2) with kernel alocated memory

I am trying to mmap() into user space a kernel buffer and am having problems. I have a simple test example, can someone please tell me what I have got wrong ? In a driver I do: uint*kva; kva = (uint*)kmalloc(4096, GFP_KERNEL); *kva = 0x11223344; printk("Address: %p %lx %x\n"
