Revision	Date	Author	Comments
1.10	25-Oct-2023	riastradh	mremap(2): Use .Lk for links in text. .%U is only for links in reference sections.
1.9	03-Mar-2023	riastradh	mremap(2): Note MAP_REMAPDUP bug. XXX pullup-10, unless we fix the bug first
1.8	01-Mar-2023	riastradh	mremap(2): Fix example to use MAP_PRIVATE. It is a historical accident that MAP_PRIVATE is assumed when neither it nor MAP_SHARED is specified. XXX pullup-9 XXX pullup-10
1.7	03-May-2018	wiz	branches: 1.7.4; 1.7.12; Sort sections. Sort ERRORS. Remove trailing whitespace.
1.6	02-May-2018	christos	Add EXAMPLE and ERRORS section.
1.5	06-May-2017	joerg	branches: 1.5.8; Extend the mmap(2) interface to allow requesting protections for later use with mprotect(2), but without enabling them immediately. Extend the mremap(2) interface to allow duplicating mappings, i.e. create a second range of virtual addresses references the same physical pages. Duplicated mappings can have different effective protections. Adjust PAX mprotect logic to disallow effective protections of W&X, but allow one mapping W and another X protections. This obsoletes using temporary files for purposes like JIT. Adjust PAX logic for mmap(2) and mprotect(2) to fail if W&X is requested and not silently drop the X protection. Improve test cases to ensure correct operation of the changed interfaces.
1.4	28-Apr-2011	wiz	branches: 1.4.34; Sort sections.
1.3	16-Feb-2008	tnn	minor pedanticism about glibc. Suggested by Joerg.
