Linux Kernel Memory Map . Memory Mapping Implementation (mmap) in Linux Kernel PPT Linux memory management subsystem is responsible, as the name implies, for managing the memory in the system 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.

Allocates size bytes, and returns a pointer to the allocated memory Bits 63 through to the most-significant implemented bit are sign extended
Understanding the Linux Kernel [Detailed Guide] Linux Magazine Bits 63 through to the most-significant implemented bit are sign extended Behind every vmalloc'ed area there is at least one unmapped page. The allocated pages are mapped to the virtual memory space behind the 1:1 mapped physical memory in the kernel space

In the Linux kernel it is possible.
