Why: The old kmap_atomic() with two arguments is deprecated, we only
keep it for backward compatibility for few cycles and then drop it.
Who: Cong Wang <amwang@redhat.com>
+
+----------------------------
+
+What: get_robust_list syscall
+When: 2013
+Why: There appear to be no production users of the get_robust_list syscall,
+ and it runs the risk of leaking address locations, allowing the bypass
+ of ASLR. It was only ever intended for debugging, so it should be
+ removed.
+Who: Kees Cook <keescook@chromium.org>
