From d3c251ab95b69f3dc189c4657baeac1b4c050789 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 28 Jun 2021 19:42:55 -0700 Subject: arch, mm: remove stale mentions of DISCONIGMEM There are several places that mention DISCONIGMEM in comments or have stale code guarded by CONFIG_DISCONTIGMEM. Remove the dead code and update the comments.
