Hi Arun,
Thanks for that excellent explanation. It's more or less clear to me now.
However, quoting what you said:
Because we have plenty of kernel virtual
address(3GB) and can easily map 2GB of RAM in to it.
Why should we have to map the whole RAM into the KVA? Shouldn't it be only
LOW_MEM?

I have two more questions from your replies:
I thought I had understood HIGH_MEM and LOW_MEM, but it appears I was wrong.
Does the concept of high memory/low memory correspond to physical
Thank you guys!
I have two more questions from your replies:
- I thought I had understood HIGH_MEM and LOW_MEM, but it appears I was
wrong. Does the concept of high memory/low memory correspond to physical
address space or virtual address space? Also, does LOW_MEM always have to
be 1
Hello,
This is my first mail on this list, so please let me know if I'm erring.
I'm reading Bovet and Cesati's Understanding the Linux Kernel,
specifically the chapter Memory Addressing, sub-section Kernel Page
Tables. Here they describe how Linux initializes its page tables for
various RAM
