We currently get three build failures on linux-next, all on MIPS, and
caused by the same patch series from Paul Burton if I read this right:

Apparently caused by dc2dd0508e19 ("MIPS: Move r4k FP code from
r4k_switch.S to r4k_fpu.S")

Same for jmr3927_defconfig, both caused by 4e967a53718f ("MIPS: Move r2300
FP code from r2300_switch.S to r2300_fpu.S").

I have no idea what exactly causes the problem. Paul, can you have a look?

My name may not be Paul but I fixed it anyway :)
