    s390: add support for vector extension · 80703617
    Martin Schwidefsky authored
    The vector extension introduces 32 128-bit vector registers and a set of
    instruction to operate on the vector registers.
    The kernel can control the use of vector registers for the problem state
    program with a bit in control register 0. Once enabled for a process the
    kernel needs to retain the content of the vector registers on context
    switch. The signal frame is extended to include the vector registers.
    Two new register sets NT_S390_VXRS_LOW and NT_S390_VXRS_HIGH are added
    to the regset interface for the debugger and core dumps.
