Documentation/arm64: Add ptdump documentation
ptdump is a debugfs interface used to dump the kernel page tables. It
provides a comprehensive overview about the kernel's virtual memory
layout, page table entries and associated page attributes. A document
detailing how to enable ptdump in the kernel and analyse its output has
been added.
Changes in V2:
- Corrected command to cat /sys/kernel/debug/kernel_page_tables
