From 8745808fda84c638e45cc860c8fb600bf4b0a2a6 Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Wed, 15 Nov 2017 17:34:22 -0800 Subject: mm, arch: remove empty_bad_page* empty_bad_page() and empty_bad_pte_table() seem to be relics from old days which is not used by any code for a long time. I have tried to find when exactly but this is not really all that straightforward due to many code movements - traces disappear around 2.4 times. Anyway no code really references neither empty_bad_page nor empty_bad_pte_table. We only allocate the storage which is not used by anybody so remove them.
