After using the `.L_xxx` lable instead of `.fixup`, we no longer place anything into a `.fixup` section, so we no longer need to place those sections into the `.text` section in the main kernel Image. Remove the use of `.fixup`. Signed-off-by: Youling Tang <tangyouling@loongson.cn> --- Using `irp` allows you to easily define multiple lables, provide convenience for implementing __{copy, clear}_user_fast in the future. arch/loongarch/kernel/vmlinux.lds.S | 1 - arch/loongarch/lib/clear_user.S | 14 +++++--------- arch/loongarch/lib/copy_user.S | 16 ++++++---------- 3 files changed, 11 insertions(+), 20 deletions(-)
