Merge branch '4.1-fp' of git://git.linux-mips.org/pub/scm/ralf/upstream-sfr into kvm_mips_queue

MIPS FP/MSA fixes from the MIPS tree. Includes a fix to ensure that the
FPU is properly disabled by lose_fpu() when MSA is in use, and Paul
Burton's "FP/MSA fixes" patchset which is required for FP/MSA support in
KVM:

> This series fixes a bunch of bugs, both build & runtime, with FP & MSA
> support. Most of them only affect systems with the new FP modes & MSA
> support enabled but patch 6 in particular is more general, fixing
> problems for mips64 systems.
