I tried to build mips:allnoconfig with the following binutils versions.
They all fail with the same errors.
	2.22 (from Poky version 1.3)
	2.22 (kernel toolchain, gcc 4.6.3)
	2.24 (kernel toolchain, gcc 4.9.0)
	2.26.1 (buildroot toolchain, gcc 5.4.0)

Bisect points to commit c4cf8e3a3e8f as the culprit.

Details are available at http://kerneltests.org/builders.
Unfortunately, just reverting this one patch doesn't work.
Reverting

f1ece3b9dd5e MIPS: Fix build with binutils 2.24.51+
f8547d2f97c8 MIPS: init upper 64b of vector registers when MSA is first used
c4cf8e3a3e8f MIPS: save/restore MSACSR register on context switch

fixes the problem, at least for an allnoconfig build with binutils 2.24.
