From 13d1b9575ac2c2da143cd2236b6cf0fc314570f8 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 25 Nov 2014 13:31:46 +0100 Subject: ARM: 8221/1: PJ4: allow building in Thumb-2 mode Two files that get included when building the multi_v7_defconfig target fail to build when selecting THUMB2_KERNEL for this configuration. In both cases, we can just build the file as ARM code, as none of its symbols are exported to modules, so there are no interworking concerns. In the iwmmxt.S case, add ENDPROC() declarations so the symbols are annotated as functions, resulting in the linker to emit the appropriate mode switches.
