Hi<div>I think it also can mean that there is a 1-1 mapping in the kernel(except for high mem) as there cannot be any page-faults in the kernel. So for memory allocated in kernel, a physical memory mapping exists, thus lessening the available physical memory.</div>

Hi,<br>
<br>
i was going through the Linux Kernel Development book. It mention the following:<br>
<br>
"Additionally, kernel memory is not pageable.Therefore, every byte of<br>
memory you consume is one less byte of available physical memory."<br>
<br>
What is the meaning of 'Kernel memory is not pageable'? Anyone can<br>
give details would help me in understanding.<br>
<br>
Thanks,<br>
Vijay<br>
