From b08d4640a3dca68670fc5af2fe9205b395a02388 Mon Sep 17 00:00:00 2001 From: Mark Salter Date: Thu, 16 Jul 2015 18:58:53 +0100 Subject: arm64: remove dead code Commit 68234df4ea79 ("arm64: kill flush_cache_all()") removed soft_reset() from the kernel. This was the only caller of setup_mm_for_reboot(), so remove that also.
