<div>My kernel virtual memory lay out is like this,</div>

<div>&&</div>
<div>
<div>In the kernel command line i had put the "vmalloc=432MB" , to reserve the vmalloc area.</div></div>
<div> </div>
<div>My question is,</div>
<div>While in the kernel memory layout, lowmem is shown as 496MB,</div>
<div>in /proc/meminfo LowMEMtotal is only 231MB.</div>
<div>Why is the difference between the two?</div>
<div> </div>
<div>How to increase the Lowmem size with reserving my vmalloc region memory(432MB)<br></div>
