Review Note

What isis Kernel KAISER?page-table isolation (KPTI) (formely KAISER?)

Kaiser hasis a strong linux kernel isolation. This means that KAISER uses a shadow address space to isolate kernel and user space separately. There is also a shadow page table that keep tracks of the bare minimum memory addresses used for context switching. Since the kernel memory is not mapped into the memory that the user can access, meltdown will not be possible.
