11 It bumps the limits to 128 PiB of virtual address space and 4 PiB of
12 physical address space. This "ought to be enough for anybody" ©.
27 == User-space and large virtual address space ==
29 On x86, 5-level paging enables 56-bit userspace virtual address space.
30 Not all user space is ready to handle wide addresses. It's known that
35 To mitigate this, we are not going to allocate virtual address space
38 But userspace can ask for allocation from full address space by
43 occupied, we look for unmapped area in *full* address space, rather than
51 to allocation from 47-bit address space.
