From 28be1b454c2bb60e317b3135211a378fa2718886 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 31 May 2017 10:12:39 +0200 Subject: [PATCH] x86/boot: Remove unused copy_*_gs() functions copy_from_gs() and copy_to_gs() are unused in the boot code. They have actually never been used -- they were always commented out since their addition in 2007: 5be865661516 ("String-handling functions for the new x86 setup code.") So remove them -- they can be restored from history if needed.
