Subject: Question about output of kmalloc()

Hello,

Below code snippet in the .ko:

unsigned long *p = (unsigned long *)kmalloc(sizeof(*p), GFP_KERNEL);
printk("Addr of p = 0x%p\n", p);

The output is:
Addr of p = 0x0000000018606ce7

In my mind, during the early day, the p should be 0xfffff...., can
anybody give some tips why the output looks like it's a physical
address?
