From a809d46066d5171ed446d59a51cd1e57d99fcfc3 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sun, 30 Mar 2014 13:20:10 +0200 Subject: MIPS: Fix gigaton of warning building with microMIPS. With binutils 2.24 the attempt to switch with microMIPS mode to MIPS III mode through .set mips3 results in *lots* of warnings like {standard input}: Assembler messages: {standard input}:397: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension during a kernel build. Fixed by using .set arch=r4000 instead. This breaks support for building the kernel with binutils 2.13 which was supported for 32 bit kernels only anyway and 2.14 which was a bad vintage for MIPS anyway.
