    MIPS: Save MSA extended context around signals · bf82cb30
    Paul Burton authored
    It is desirable for signal handlers to be allowed to make use of MSA,
    particularly if auto vectorisation is used when compiling a program.
    The MSA context must therefore be saved & restored before & after
    invoking the signal handler. Make use of the extended context structs
    defined in the preceding patch to save MSA context after the sigframe
    when appropriate.
