From 490741ab1beb9c9f6580e30c7cd91b17a7560369 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 7 Jun 2020 21:42:52 -0700 Subject: module: move the set_fs hack for flush_icache_range to m68k flush_icache_range generally operates on kernel addresses, but for some reason m68k needed a set_fs override. Move that into the m68k code insted of keeping it in the module loader.
