    MIPS: Tidy up FPU context switching · 1a3d5957
    Paul Burton authored
    Rather than saving the scalar FP or vector context in the assembly
    resume function, reuse the existing C code we have in fpu.h to do
    exactly that. This reduces duplication, results in a much easier to read
    resume function & should allow the compiler to optimise out more MSA
    code due to is_msa_enabled()/cpu_has_msa being known-zero at compile
    time for kernels without MSA support.
