Linux Kernel Memory Map . Understanding of Linux virtual memory and physical memory Programmer Sought vmalloc space is lazily synchronized into the different PML4/PML5 pages of the processes using the page fault handler, with init_top_pgt as reference. This eliminates the overhead of copying user space information into the kernel space and vice versa.
