Subject[PATCH v3 01/29] x86: boot/copy, remove unused functions
Date
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 5be865661516 ("String-handling functions for the new x86
setup code.") in 2007. So remove them -- they can be restored from
history if need be.
